Pros
- 12+4 power stages with alloy chokes and a ProCool II connector feed high core-count Ryzen chips
- Dual M.2 slots each with their own heatsink, plus a passive chipset heatsink with no fan to whine
- 2.5 Gb LAN alongside Intel Gigabit Ethernet gives two wired ports for gateway teaming
- WiFi 6E and Bluetooth 5.2 built in, freeing the PCIe slot a wireless card would take
- Front-panel USB 3.2 Gen 2 Type-C header plus rear Type-A and Type-C connectors
Cons
- AM4 socket only, so Ryzen 7000 series and later AM5 processors will not fit
- Display outputs are HDMI 2.0 and DisplayPort 1.2, dated standards for anyone running an APU without a graphics card
- Full ATX footprint needs a full-size case; there is no Micro-ATX version of this board
This is the refreshed X570S revision, and the changes concentrate on power delivery and cooling rather than on layout.
- 12+4 power stages with alloy chokes, durable capacitors and the ProCool II CPU power connector
- Passive chipset heatsink, so there is no small chipset fan to age and buzz
- VRM heatsink with an 8 mm heatpipe tying the two banks together
- Dual on-board M.2 heatsinks plus a dedicated water pump header
- PCIe 4.0 across the primary slot and both M.2 sockets
The passive cooling is the point of the S revision. Earlier X570 boards used an active chipset fan that sat under the graphics card and became a known noise source over time; removing it changes the acoustic character of the whole build.
Socket support is broad within AM4, which is what makes this board a sensible base for either a new build or a drop-in upgrade.
- Ryzen 5000 and 5000 G-Series, the final and fastest AM4 generation
- Ryzen 4000 G-Series, 3000 and 3000 G-Series also supported
- Ryzen 2000 and 2000 G-Series covered as well, though a BIOS update may be needed on older stock
- AMD StoreMI for tiering a fast drive in front of a larger one
Check the case first: this is a full ATX board and it wants seven expansion slots and standard ATX standoffs. Also confirm your supply has the eight-pin plus four-pin CPU leads the ProCool II arrangement expects before ordering.
The networking and storage side is where this board still holds up against newer platforms.
- WiFi 6E on 802.11ax with MU-MIMO adds the 6 GHz band, which is far less congested than 5 GHz in flats and shared houses
- 2.5 Gbps LAN pairs with the Intel Gigabit port, so a NAS and a router can be served separately
- Two PCIe 4.0 M.2 drives can run without stealing bandwidth from the graphics slot
The honest ceiling is the socket. AM4 ends with the Ryzen 5000 series, so the upgrade room here is in storage, memory and graphics rather than in processors. If you want a platform that will take several more CPU generations, this is the wrong socket to start on.
Pros
- 12+2 teamed power stages with alloy chokes and a ProCool connector hold steady under a 16-core AM4 chip
- On-board Wi-Fi 6E pairs with Intel 2.5 Gb Ethernet, so both wireless and wired clear gigabit
- Dual M.2 slots with the primary wired PCIe 4.0 x4 for 7,000 MB/s class drives
- BIOS Flashback rewrites firmware from a USB stick with no CPU or memory installed
- HDMI 2.1 and DisplayPort 1.2 outputs drive a display straight from a G-series APU with no graphics card fitted
Cons
- AM4 is a closed socket, so any future CPU jump means replacing the board as well
- The chipset only feeds PCIe 3.0, so the second M.2 and the lower slots run at half the bandwidth of the primary pair
- No rear Thunderbolt or USB4 port on the back panel
This is a full ATX board built around the AMD B550 chipset and the AM4 socket.
- The VRM uses 12+2 teamed power stages with alloy chokes and durable capacitors, which is generous headroom for a 105W part and leaves room for a manual overclock.
- A ProCool solid-pin power connector replaces the usual hollow-pin header, cutting contact resistance where the 8-pin EPS lead meets the board.
- Heatsinks cover the VRM and both M.2 positions, with no fan on the chipset.
- An addressable Gen 2 RGB header plus Aura Sync ties case lighting to the board.
Layout follows the usual pattern with the primary M.2 sitting between the socket and the top graphics slot, so drives there run warmer than the lower position under sustained writes.
The AM4 socket accepts Ryzen 3000 and 5000 series desktop chips plus 4000 and 5000 G-series APUs. Older 2000 series parts are not supported by B550 boards.
- Fit a G-series APU and the HDMI 2.1 and DisplayPort 1.2 outputs work directly, so the machine can be built and tested before a graphics card arrives.
- Bluetooth v5.2 and Wi-Fi 6E come from the on-board module, with the antenna screwing onto the rear panel.
- As a standard ATX board it needs a case with nine mounting standoffs; microATX chassis will not take it.
If the CPU you have chosen is newer than the board revision on the shelf, use BIOS Flashback first. It updates firmware with no processor installed, which avoids the classic dead-on-arrival boot loop.
Upgrade headroom on this platform splits cleanly in two.
- Storage and graphics stay open. The primary M.2 and the top x16 slot both run PCIe 4.0 from the CPU, so a current graphics card and a fast NVMe drive are fully fed.
- The CPU path is finite. AM4 ended with the Ryzen 5000 series, so the ceiling is fixed - a 5800X3D or 5950X is as far as it goes, and anything beyond that means a new board, memory and processor together.
Networking ages well here: 2.5 Gb Ethernet and Wi-Fi 6E both outlast the socket. The sensible way to read this board is as the final stop on a mature platform - excellent if you already own AM4 memory and a chip, less appealing as the base for a machine you plan to grow for another five years.
Pros
- 12+2 phase digital VRM with DrMOS under an enlarged heatsink, sized for 12 and 16 core AM4 processors
- Two PCIe 4.0 x4 M.2 sockets, each sitting under its own thermal guard
- Four DDR4 DIMM slots running dual channel non-ECC unbuffered memory
- Intel dual-band 802.11ac Wi-Fi with Bluetooth 4.2 alongside Intel Gigabit LAN with cFosSpeed
- Q-Flash Plus rewrites the firmware from a FAT32 USB stick with no processor, memory or graphics card fitted
Cons
- Wi-Fi is 802.11ac with Bluetooth 4.2, both a generation behind current Wi-Fi 6 boards
- The X570 chipset uses an active fan, which adds a moving part and a potential noise source to the build
- AM4 and DDR4 only, so a move to Ryzen 7000 means replacing the board and the memory together
Two areas separate a serious X570 board from a basic one, and both are addressed here.
- 12+2 phase digital VRM with DrMOS, enough current delivery to hold clocks on a 12 or 16 core AM4 processor rather than throttling under a sustained all-core load
- An enlarged heatsink across the VRM area, which is what keeps that delivery stable in a warm case
- Two PCIe 4.0 x4 M.2 sockets, each with its own thermal guard. High-speed NVMe drives throttle when they get hot, so the heatspreaders are functional rather than decorative
PCIe 4.0 is the reason to choose X570 over the older chipsets, since it doubles available bandwidth to both the graphics slot and the M.2 drives. Audio uses high-quality capacitors with a noise guard and an LED trace path that isolates the audio section from the rest of the board.
The socket is AM4, and the supported processor list is broad within that family.
- AMD 3rd Gen Ryzen, 2nd Gen Ryzen, 2nd Gen Ryzen with Radeon Vega graphics, plus earlier Ryzen with Vega parts
- Ryzen 5000 series chips are supported after a firmware update, which is where Q-Flash Plus earns its place
- Four DDR4 DIMM slots in dual channel, non-ECC unbuffered
Fill slots two and four first for dual channel if you are using two modules, as the manual specifies. Memory speed above the JEDEC default requires enabling the XMP profile, otherwise a fast kit will idle at a conservative base speed. If a board arrives on older firmware and you plan to fit a Ryzen 5000 chip, flash it before installing that processor rather than after.
Networking, front panel connections and firmware recovery are the day-to-day features here.
- Intel dual-band 802.11ac Wi-Fi and Bluetooth 4.2 on board, with an Intel Gigabit LAN port carrying the cFosSpeed traffic shaper
- A front USB 3.1 Gen2 Type-C header, so a modern case front panel connects properly rather than through an adapter
- RGB Fusion 2.0 with multi-zone addressable lighting and headers for both addressable and standard strips
- Smart Fan 5 with several temperature sensors and hybrid fan headers that support fan stop
Q-Flash Plus is the standout. Copy the file to a FAT32 USB stick, rename it GIGABYTE.bin, insert it in the marked rear port, connect the 8-pin and 24-pin power leads and press the button. No processor, memory or graphics card is required.
Pros
- Digital twin 12+2 power phase design with premium chokes for steady delivery to Ryzen 5000 chips
- Two M.2 sockets, one on PCIe 4.0 with a thermal plate and one on PCIe 3.0
- Q-Flash Plus writes firmware from a USB stick with no CPU or memory installed
- 2.5 GbE wired networking alongside Wi-Fi 6 for machines that move between cable and radio
- Front-panel USB 3.2 Gen 1 Type-C header plus five rear Type-A ports across two speed grades
Cons
- AM4 ended at Ryzen 5000, so there is no path to a Ryzen 7000 or newer chip on this socket
- The second M.2 socket runs at PCIe 3.0, halving throughput for a Gen 4 drive
- Rear panel lists Type-A ports only, with the Type-C connector reserved for a front-case header
An ATX board on the AMD B550 chipset for socket AM4, built around Ryzen 5000, 4000 and 3000 series desktop chips.
- Power: digital twin 12+2 phase with premium chokes and capacitors
- Memory: four DDR4 slots with Extreme Memory Profile support
- Expansion: PCIe 4.0 x16 with reinforced armour on the slot
- Storage: one PCIe 4.0 M.2 socket and one PCIe 3.0 M.2 socket
- USB: two rear 3.2 Gen 2 Type-A, three rear 3.2 Gen 1 Type-A, one front Gen 1 Type-C header
An advanced VRM heatsink and an M.2 thermal guard handle the two hottest areas, and the integrated I/O shield removes the fiddly step of clipping a loose plate into the case first.
Q-Flash Plus is the feature worth knowing about, because it lets a board shipped with older firmware accept a newer Ryzen chip without borrowing a processor to boot with.
- Download the firmware file for this exact model from the maker website
- Uncompress it, copy it to a FAT32 or FAT16 USB stick and rename it GIGABYTE.bin
- Insert the stick in the white USB port on the rear panel
- Connect the CPU 8-pin and the 24-pin main power, then press the Q-Flash Plus button
- Wait two to three minutes until the indicator stops flashing
No CPU, memory or graphics card needs to be installed for this to work. Afterwards, install the hardware normally and load the default profile before switching the memory profile on.
Treat this as the end station for an AM4 build rather than a launch pad. The socket closed with Ryzen 5000, so the strongest chips available are already on the market, and moving to a newer generation means a new board, new memory and a new cooler mount.
What can still grow: the PCIe 4.0 x16 slot takes any modern graphics card the case will hold, the Gen 4 M.2 socket accepts a fast NVMe drive, and the 2.5 GbE port keeps up with multi-gig home wiring.
Memory is the sticking point. DDR4 kits stay with this platform, since the following generation moved to DDR5 modules with a different notch and a different voltage design.
Pros
- 12-phase digital VRM (10+2 configuration) with Intersil digital PWM gives steadier power delivery under sustained CPU loads
- Dual M.2 NVMe slots support PCIe 4.0/3.0 x4 drives, each under its own thermal guard
- Four DDR4 DIMM slots run in dual channel and accept ECC or non-ECC unbuffered memory
- Stainless steel PCIe Armor reinforces the primary graphics card slot against heavy GPU sag
- Realtek GbE 8118 LAN pairs with onboard bandwidth management for prioritizing network traffic during gaming
Cons
- Built for AMD Ryzen 3000/2000 series sockets only, so it will not accept Intel processors
- HDMI output is capped at version 2.0b, a step behind the 2.1 spec found on newer boards
- Onboard audio uses the Realtek ALC887 codec, a mid-tier chip rather than the higher-end ALC1220 found on premium boards
Built in the full ATX form factor, the X570 Gaming X centers on a 12-phase digital VRM (a 10+2 configuration using Intersil digital PWM controllers) designed to keep voltage stable to the CPU under sustained load. Four DDR4 DIMM slots run in dual channel and accept either ECC or non-ECC unbuffered memory modules.
- Form factor: ATX
- VRM: 12-phase digital (10+2), Intersil PWM
- Memory: 4x DDR4 DIMM, dual channel, ECC/non-ECC unbuffered
- Audio: Realtek ALC887 codec with dedicated audio capacitors and noise guard
A one-piece stainless steel PCIe Armor shield reinforces the primary expansion slot, adding resistance to the physical stress that heavier graphics cards place on the slot over time.
The board is built around the AMD X570 chipset and supports 3rd Gen Ryzen, 2nd Gen Ryzen, and Ryzen processors with Radeon Vega graphics, covering the AM4 socket lineup available at the time of its release. PCIe 4.0 lanes run to both the primary graphics slot and the dual M.2 NVMe storage slots, each of which includes its own thermal guard to manage drive temperatures.
- Socket support: AMD AM4 (3rd/2nd Gen Ryzen, Ryzen with Vega graphics)
- Expansion: PCIe 4.0/3.0 slots
- Storage: dual M.2 NVMe PCIe 4.0/3.0 x4
- Networking: Realtek GbE 8118 LAN with bandwidth management
Because the socket is AM4-specific, this board is not an option for Intel-based builds, and older BIOS versions may need updating via Gigabyte's Q-Flash Plus system before newer Ryzen 5000-series CPUs will boot.
Dual M.2 NVMe slots give room to add a second high-speed drive later without giving up a PCIe expansion slot, and the four DIMM slots leave headroom to grow from a 2-module memory kit up to a denser 4-module configuration. RGB Fusion 2.0 headers also allow lighting peripherals to be added incrementally as a build evolves.
- Storage headroom: second M.2 NVMe slot available
- Memory headroom: up to 4 DIMMs total
- Lighting: RGB Fusion 2.0 addressable headers
- BIOS: Q-Flash Plus for CPU-less firmware updates
Because Gigabyte has released BIOS updates extending support toward Ryzen 5000-series processors, checking the current firmware version before an upgrade prevents a compatible CPU from failing to post on outdated BIOS.
Pros
- 10+3 phase digital VRM design with premium chokes and capacitors for stable power under sustained Ryzen loads
- Supports DDR4 memory up to 4733 MT/s across 4 DIMM slots with AMD EXPO profile support
- Dual M.2 slots plus a PCIe 4.0 x16 slot give room for a fast NVMe boot drive and a second storage drive
- Built-in Wi-Fi 6 and Gigabit LAN cover both wireless and wired networking without an add-in card
- PCIe EZ-Latch and pre-installed I/O armor speed up graphics card installation and rear-panel assembly
Cons
- Limited to DDR4 memory, so it cannot use newer DDR5 modules as those become the default standard
- AM4 socket only supports Ryzen 3000/4000/5000 series, with no upgrade path to AMD's newer AM5 platform
- Single PCIe 4.0 x16 slot means no dual-GPU or multi-card expansion beyond the primary graphics slot
The B550 Eagle WIFI6 runs a 10+3 phase digital VRM design built with premium chokes and capacitors, paired with enlarged VRM heatsinks and 5 W/mK thermal pads to keep power delivery stable under sustained CPU loads.
- 2x M.2 slots for NVMe storage alongside a PCIe 4.0 x16 graphics slot
- 4x DDR4 DIMM slots supporting speeds up to 4733 MT/s with AMD EXPO
- USB 3.2 Gen 2 and USB 3.2 Gen 1 Type-C ports on the rear I/O
- Built-in Wi-Fi 6 and Gigabit LAN for wired or wireless networking
The thermal armor and pre-installed I/O shield are aimed at reducing build time for a full system assembly.
This ATX board uses the AM4 socket and is built to run AMD Ryzen 5000, Ryzen 4000, and Ryzen 3000 series processors, giving builders a range of CPU generations to choose from on a single platform.
- 4 DDR4 DIMM slots support AMD EXPO memory profiles for tuned memory speeds
- PCIe 4.0 x16 slot is compatible with current and previous-generation graphics cards
- 2x M.2 slots accept NVMe or SATA-based M.2 drives depending on model
Because it is DDR4-only, memory bought for this board will not carry over to a future DDR5 platform, something to weigh for builders planning a longer-term upgrade path.
The AM4 socket sits at the end of its processor lifecycle, meaning Ryzen 3000 through 5000 series chips are the ceiling for CPU upgrades on this board rather than newer AM5-based Ryzen processors.
- Dual M.2 slots allow adding a second NVMe drive later without replacing the board
- PCIe EZ-Latch and EZ-Latch WiFi simplify swapping a graphics card or Wi-Fi module during future upgrades
- RGB Fusion header support lets builders add or change lighting accessories over time
It suits a build meant to run its full lifecycle on AM4 rather than one intended to carry forward to a next-generation AMD platform.

Pros
- 14+2+2 power stage design rated for 80A per stage, supporting demanding multi-core AM5 processors
- Four M.2 slots plus PCIe 5.0 support give substantial storage expansion room
- Integrated WiFi 7 with Q-Antenna and 2.5G LAN cover both wireless and wired high-speed networking
- USB Type-C port with 20Gbps transfer speed handles fast external drives and docks
- AMD AM5 socket supports Ryzen 7000, 8000, and 9000 series processors without a new socket change
Cons
- B850 chipset trims some PCIe lanes and features found on higher-tier X870E boards, a trade-off for the lower chipset tier
- WiFi 7 benefits require a WiFi 7-capable router; older routers fall back to WiFi 6 or lower speeds
- ATX form factor needs a full-size case, ruling out small-form-factor builds
The board runs a 14+2+2 power stage design rated for 80A per stage, delivered through an 8+8-pin ProCool power connector, high-quality alloy chokes, and durable capacitors — a power delivery design built for sustained multi-core loads on Ryzen 9000, 8000, and 7000 series processors on the AM5 socket. DDR5 memory support includes ASUS AEMP for tuned memory profiles without manual timing adjustments.
Storage runs through four M.2 slots with PCIe 5.0 support for the fastest NVMe drives, and networking covers WiFi 7 with a Q-Antenna design plus 2.5G wired LAN. A 20Gbps USB Type-C port rounds out the external I/O for high-speed peripherals and docks.
Confirm any AM5 Ryzen 7000, 8000, or 9000 series processor before buying, since the socket doesn't support older AMD platforms. DDR5 is required — this board has no DDR4 option — so plan for DDR5 memory kits if upgrading from an older system.
- Verify your case supports full ATX boards before purchase
- Check your router supports WiFi 7 to get the full wireless speed benefit
- Pair the 8+8-pin power connector with a PSU that has matching cables
ASUS AI Networking II and AI Advisor are meant to simplify initial setup by auto-tuning network and system settings, reducing the manual BIOS tweaking usually needed to get a new build stable.
Because the AM5 socket is shared across three processor generations so far, this board gives a runway to upgrade the CPU later without replacing the motherboard, as long as future BIOS updates keep supporting new releases. The four M.2 slots with PCIe 5.0 support mean storage can be expanded significantly before running out of NVMe bandwidth.
The trade-off against ASUS's higher-tier X870E boards is fewer total PCIe lanes and some feature trims tied to the B850 chipset, which matters most for multi-GPU or heavily expanded PCIe setups rather than typical single-GPU gaming builds. For most builders prioritizing a strong single-GPU system with room to add fast NVMe storage, the B850-A's lane allocation is unlikely to be a limiting factor.
Pros
- Dual M.2 slots, one wired for PCIe 4.0 x4 NVMe drives, allow two SSDs without an add-in card
- Built-in WiFi 6 (802.11ax) and 1Gb LAN cover both wireless and wired networking out of the box
- HDMI 2.1 output handles 4K video at 60Hz for onboard graphics setups
- VRM and PCH heatsinks plus hybrid fan headers give the board dedicated cooling zones beyond the CPU socket
- Supports AM4 Ryzen 5000, 5000G, 4000G and 3000 series desktop processors
Cons
- Micro ATX form factor limits expansion to fewer slots than a full ATX board on the same chipset
- Single PCIe 4.0 x16 slot means only one full-bandwidth graphics card can be installed
- RGB lighting relies on an onboard header for external strips, since no onboard LED array is built in
This micro ATX board pairs the AM4 socket with a PCIe 4.0 x16 slot for the graphics card and dual M.2 slots, one of which runs at PCIe 4.0 x4 for high-throughput NVMe storage. Display output includes HDMI 2.1 for 4K at 60Hz alongside D-Sub and DVI-D for older monitors.
- PCIe 4.0 x16 SafeSlot for the primary graphics card
- Dual M.2 slots, one at PCIe 4.0 x4
- HDMI 2.1, D-Sub and DVI-D video outputs
- USB 3.2 Gen 2 Type-A ports on the rear I/O
A stainless-steel reinforced rear I/O shield and dedicated VRM and PCH heatsinks round out a build focused on stable power delivery in a compact micro ATX footprint.
The board is built around the AM4 socket and supports 3rd Gen Ryzen, Ryzen 5000, Ryzen 5000G and Ryzen 4000G series desktop processors. Onboard WiFi 6 (802.11ax) and 1Gb LAN mean a network connection is available without a separate card.
- AM4 socket for 3000, 4000G and 5000-series Ryzen CPUs
- WiFi 6 (802.11ax) built into the board
- 1Gb Ethernet LAN port
- Onboard addressable RGB header for Aura Sync-capable strips
Because socket support stops at AM4, this board is not a path onto AM5 or Intel platforms — CPU upgrades are limited to the Ryzen generations listed for this socket.
ASUS OptiMem trace layout is designed to let RAM kits run at higher frequencies without needing extra voltage, useful when upgrading to faster memory later. Storage can grow through the second M.2 slot or SATA ports without touching the primary boot drive.
- ASUS OptiMem layout supports higher-frequency RAM kits
- Second M.2 slot available for adding storage post-purchase
- 5X Protection III covers overcurrent and overvoltage on expansion components
- Fan Xpert 2 utility remaps cooling as components are added
Because the board tops out at AM4 and micro ATX sizing, a future jump to a newer CPU socket or a multi-GPU layout will require a full motherboard swap rather than an in-place upgrade.
What Is PCIe 4.0 and Why It Matters on a Motherboard
PCIe 4.0 doubles the per-lane bandwidth of PCIe 3.0, moving from roughly 1 GB/s to about 2 GB/s per lane. On a motherboard, that extra headroom shows up mainly in two places: your M.2 SSD slots and your primary graphics card slot. A PCIe 4.0 NVMe drive can reach sequential speeds well beyond 7,000 MB/s, close to double what a typical PCIe 3.0 drive manages.
For gaming, the real-world frame rate gap between PCIe 3.0 and 4.0 graphics cards is usually small. The bigger win shows up in storage: faster level loads, quicker file transfers, and less waiting during large game installs. If you’re also shopping for a drive to match, our guide to the best PCIe 4.0 SSDs pairs well with any board on this list.
Chipset matters too. On AMD, B550 and X570 boards support PCIe 4.0, while older A320 and B450 boards do not. On Intel, PCIe 4.0 support started with 500-series chipsets and continues through B760 boards paired with 12th-, 13th-, and 14th-gen CPUs.
Key Features to Check Before Choosing a PCIe 4.0 Board
Not every board labeled “PCIe 4.0” delivers the same experience. A handful of specs decide whether you get a smooth build or a frustrating one.
Chipset and CPU Platform
Match the socket and chipset to your CPU first. AM4 boards fit Ryzen 3000 through 5000 chips, AM5 boards fit newer Ryzen processors with DDR5, and Intel’s LGA 1700 socket covers 12th- through 14th-gen chips on B760 boards. Buying the wrong socket is the single most common mistake first-time builders make.
VRM and Power Delivery
The VRM, or voltage regulator module, feeds clean power to your CPU. A board with weak VRM cooling can throttle under sustained load, especially with higher-core-count chips. Look for dedicated VRM heatsinks if you plan demanding workloads or any overclocking.
M.2 Slot Count and Layout
Most PCIe 4.0 boards include at least two M.2 slots, but placement matters as much as count. A slot sandwiched next to your GPU can run hotter, so check whether the board includes M.2 heatsinks before you add a second or third drive.
Networking and Connectivity
WiFi 6E and 2.5 Gb LAN are common on mid-range and higher boards now, and both make a real difference if you stream, transfer large files, or game online often. Budget boards sometimes drop one or both, so confirm what you actually need before you buy.
Best Motherboards with PCIe 4.0 for Every Build and Budget
Here’s how the 10 picks in this roundup break down by the situations they fit best, based on chipset, price, and feature set.
Best Overall
The ASUS ROG Strix B550-F Gaming WiFi II holds a 4.6-star rating across more than three thousand reviews, which says a lot about consistency at this price point. It pairs a solid VRM with WiFi 6E, 2.5 Gb LAN, and BIOS Flashback for firmware updates without a CPU installed. For most AM4 builders who want dependable PCIe 4.0 support without overspending, this is the board to start with.
Best Value Pick
If you want PCIe 4.0 without stretching your budget, the GIGABYTE B550 Eagle WIFI6 covers the essentials at a lower price than most competitors. It supports Ryzen 3000 through 5000 chips, includes dual M.2 slots, and still adds WiFi 6 and 2.5 Gb LAN. It’s the most affordable board here that doesn’t ask you to sacrifice core features.
Best for High-End Gaming Rigs
Builders chasing top-tier VRM headroom and premium connectivity should look at the ASUS ROG Strix X570-E Gaming WiFi II. Its 12+4 power stage design and passive PCH heatsink give it more thermal margin for high-core-count Ryzen chips than most B550 boards. It costs more, so it fits best once you’ve already picked a flagship CPU and want a board to match.
Best CPU and Motherboard Combo
New builders on a strict budget should consider the Micro Center AMD Ryzen 5 5500 with GIGABYTE B550M K combo, which bundles a capable CPU with a PCIe 4.0-ready board in a single purchase. It carries a perfect 5-star rating from early buyers, though the review count is still small. For anyone building a first PC from scratch, skipping separate CPU shopping simplifies the whole process.
Best Compact Micro-ATX Pick
Smaller cases call for smaller boards, and the ASUS Prime B550M-A WiFi II fits Micro-ATX cases while still supporting PCIe 4.0, WiFi 6, and HDMI 2.1. It skips some of the RGB and premium VRM cooling found on pricier boards, so it suits builders who prioritize size and price over overclocking headroom.
Best for Intel Builds
If you’re on Intel rather than AMD, the MSI PRO B760-P WiFi DDR4 supports 12th-, 13th-, and 14th-gen chips while keeping DDR4 memory costs down. It includes 2.5 Gbps LAN and WiFi 6E, matching most AM4 boards on connectivity. For a deeper look at Intel-specific options, our guide to the best Intel motherboards covers more chipsets and price points.
Best for Next-Gen AM5 Builds
Builders ready to move past AM4 should look at the ASUS ROG Strix B850-A Gaming WiFi, which supports DDR5 memory and newer Ryzen chips while staying friendly with PCIe 4.0 peripherals alongside its faster PCIe 5.0 slot. It’s a forward-looking pick if you plan to keep the platform for several CPU generations. Our roundup of the best AM5 motherboards digs deeper into this newer platform if you want more comparisons.
AMD vs Intel: Which Platform Fits Your Build
AMD’s AM4 platform remains one of the most cost-effective ways into PCIe 4.0, especially now that B550 boards are widely discounted. AM5 costs more upfront but supports DDR5 and a longer CPU upgrade path. Intel’s B760 boards keep DDR4 compatibility, which can lower your total build cost if you already own memory.
Neither platform wins across every build. Choose AMD AM4 if you want the lowest entry price today, AM5 if you’re planning multiple CPU upgrades over the next few years, and Intel B760 if you already lean toward Intel or want to reuse existing DDR4 sticks. If gaming performance is your main concern regardless of platform, our guide to the best motherboards for gaming compares boards purely on gaming-focused features.
Common Mistakes to Avoid When Buying a PCIe 4.0 Motherboard
A few habits trip up buyers who are new to PCIe 4.0 shopping. Watching for these ahead of time saves you a return shipment or a bottlenecked build.
- Assuming every board on a PCIe 4.0-capable chipset runs every slot at full 4.0 speed. Secondary M.2 slots sometimes step down to PCIe 3.0 depending on how the board allocates lanes.
- Ignoring VRM cooling on higher-core-count CPU pairings, which can lead to thermal throttling under sustained loads.
- Buying a board with weak connectivity, then discovering later you need WiFi 6E or 2.5 Gb LAN for your setup.
- Overlooking BIOS Flashback support, which lets you update firmware before installing a CPU — handy for newer chips paired with older board revisions.
- Choosing based on RGB or looks alone rather than power delivery and expansion slots that actually match your build plans.
Frequently Asked Questions
Do all PCIe 4.0 motherboards support PCIe 4.0 SSDs and PCIe 4.0 GPUs equally?
Not always. The primary GPU slot usually runs at full PCIe 4.0 speed, but secondary M.2 slots or extra PCIe slots sometimes step down to PCIe 3.0 depending on how the board allocates lanes. Check the manual’s block diagram if you plan to use multiple high-speed devices at once.
Is PCIe 4.0 worth it over PCIe 3.0 for gaming?
For most games, the frame rate difference between PCIe 3.0 and 4.0 graphics cards stays small, often within a few percent. The bigger benefit comes from PCIe 4.0 storage, which loads levels and transfers files noticeably faster than older drives.
Can I use a PCIe 4.0 motherboard with an older CPU?
It depends on the platform. Many AM4 B550 boards support Ryzen 3000 chips, but PCIe 4.0 itself only activates with Ryzen 3000 or newer processors. Older Ryzen 1000 and 2000 series chips will still boot but run slots at PCIe 3.0 speeds.
Do I need WiFi built into my motherboard?
Only if you don’t plan to run an ethernet cable to your router. Built-in WiFi 6 or 6E adds convenience and shows up on mid-range boards now, but a wired connection is generally faster and more stable if it’s practical in your space.
How much should I budget for a solid PCIe 4.0 motherboard?
Capable boards start well under one hundred fifty dollars and cover the core features most builders need. Spend more only once you need premium VRM cooling for a high-core-count CPU, WiFi 6E, or a next-gen AM5 platform with DDR5 support.
Whichever board you land on, match it to your CPU platform first and your feature wishlist second. A well-chosen PCIe 4.0 motherboard should disappear into the background of your build, quietly handling power delivery and storage bandwidth while you focus on the parts you actually notice day to day. When you’re ready, compare specs and current pricing on the picks above before you finalize your parts list.
