§ Shortlist

The three worth arguing about

01
01 / 08

01 / Our pick

ASUS Prime B850-PLUS Wifi AMD B850 Socket AM5 ATX

  • Wi-Fi 6E and 2.5Gb Ethernet included as standard at a budget price point, beating most competing boards in this bracket
  • PCIe Gen 5 support for both the primary GPU slot and M.2 storage provides meaningful future-proofing over B650 alternatives
  • 6-layer PCB construction rather than the 4-layer design that some budget boards use, improving signal integrity and thermal performance

Where it gives up

VRM phase count and MOSFET specifications are not publicly documented, making it difficult to assess suitability for high-end Ryzen 9 chips under sustained load. Not well suited to serious manual overclocking, as B850 lacks the full overclocking toolkit reserved for X870 boards.

Rated 4.4 by 37 owners. Our review scores it 8.0.

What the numbers mean

You can, and you should. What follows is the part a sheet can’t do: the working between what these products have and what your desk actually needs, kept word for word.

Finding the right motherboard without overspending is genuinely tricky, especially with ASUS offering so many options across their PRIME, TUF, and ROG lines. We put together this guide to the Best ASUS Motherboards Under £300 UK 2026 | 6 Tested to cut through the noise and give you honest, practical advice. Whether you're building a fresh AM5 system or squeezing more life out of an AM4 platform, there's something here for you. We've looked at 12 boards in total, covering everything from a sub-£55 bare-bones option to a feature-packed X870 board sitting just under the £240 mark. Here's what actually matters.

12. MSI B650M PROJECT ZERO Back-Connect Micro-ATX

Price: £212.49 | Rating: ★★★★☆ (4.4)

MSI B650M PROJECT ZERO Back-Connect Micro-ATX Motherboard

Here's what makes this one different: the connectors live on the back of the board rather than the front. MSI's PROJECT ZERO design routes the 24-pin, fan headers, and the rest around the rear, so with a compatible case you get a genuinely tidy build with almost no visible cabling. It's built on AMD's B650 chipset with the AM5 socket, supports Ryzen 9000 chips, and squeezes all of that into a compact Micro-ATX form factor.

The VRM is a direct 10+2 power design, which is more than respectable for a board this size, and it'll happily run a Ryzen 9 without thermal drama. Memory support goes up to DDR5 6400+MHz with overclocking, and you get two Gen4 M.2 slots for storage. WiFi 6E is onboard, so wireless is quick out of the box, and there's a single PCIe 4.0 x16 slot for your graphics card.

The back-connect approach is genuinely clever, but there's a catch worth flagging: you need a case designed for it. Drop this into a standard chassis and those rear connectors have nowhere to go. So factor that into your budget and planning before you commit. If you're building fresh and buying a matching case anyway, it's a non-issue.

For a Micro-ATX build where looks matter as much as performance, this is a smart pick. It's not the board for someone who wants four M.2 slots or PCIe 5.0, but the clean-build payoff is real, and the pricing sits comfortably under our cap. If you've never seen a back-connect build in the flesh, the cable-free result is worth the extra planning.

Pros

  • Back-connect design for a properly clean build
  • Direct 10+2 VRM handles Ryzen 9000 chips well
  • Two Gen4 M.2 slots and WiFi 6E included
  • Compact Micro-ATX form factor
  • DDR5 6400+MHz memory support with OC

Cons

  • Needs a back-connect compatible case to work
  • PCIe 4.0 rather than 5.0 for the GPU slot
  • Only two M.2 slots, fewer than larger ATX rivals

Buying Guide: What to Look For in the Best ASUS Motherboards Under £300 UK 2026 | 6 Tested

Socket and Platform First

This is the most important decision you'll make. AM5 (for Ryzen 7000 and 9000 series) is the current AMD platform and the one to choose for new builds in 2026. AM4 (for Ryzen 1000 through 5000 series) is mature and well-supported, but it's not getting new CPU releases. LGA1151 (Intel Z370) is effectively a dead platform. If you're building new, go AM5. If you're upgrading an existing system, match your current socket.

Chipset Matters

On AM5, the chipsets rank roughly like this: A620 (basic, no overclocking) sits at the bottom, then B650, then B850, then X670, then X870 at the top. For most people, B850 hits the sweet spot. It offers PCIe 5.0 for both GPU and M.2, decent USB connectivity, and a reasonable price. X870 adds more PCIe lanes and better USB options, which matters if you're running multiple high-speed storage devices.

Power Delivery

Look at the power stage count and amperage rating. For a Ryzen 9 chip or serious overclocking, you want at least 12 power stages with 60A or higher DrMOS components. For mainstream Ryzen 5 or 7 builds at stock speeds, 10 to 12 stages is fine. The TUF boards in this roundup generally have stronger power delivery than PRIME boards at similar prices.

M.2 Slots

One M.2 slot is the minimum. Two is comfortable for most builds (OS drive plus a secondary storage drive). Three or four slots are useful if you're running a NAS-style setup or need lots of fast storage. Check whether the M.2 slots support PCIe 5.0 or PCIe 4.0, as Gen 5 SSDs are becoming more common.

Connectivity

WiFi 6 is the minimum worth considering in 2026. WiFi 6E and WiFi 7 are better if your router supports them. For ethernet, 2.5Gb is the sweet spot. USB4 or Thunderbolt support is a bonus for high-speed peripherals. Check the rear I/O for USB-C ports, as these are increasingly important for modern peripherals.

Form Factor

ATX is the standard full-size format and offers the most expansion slots. Micro-ATX is smaller and fits in compact cases, but with fewer slots. Make sure your case supports your chosen form factor before buying.

Common Mistakes to Avoid

Don't buy an AM4 board for a new build in 2026 unless you have a specific reason. Don't overspend on a premium chipset if you're running a mid-range CPU. And always check that your chosen CPU is compatible with the board's BIOS version before assuming it'll work out of the box.

Best Overall Value

1. ASUS PRIME B850-PLUS WIFI AMD B850 Socket AM5 ATX

Price: £115.99 | Rating: ★★★★☆ (4.4)

Here's the thing: if you're building a new PC in 2026 and you want a board that won't feel outdated in two years, the ASUS PRIME B850-PLUS WIFI is where most people should start. It sits on AMD's B850 chipset with the AM5 socket, which means full DDR5 support, PCIe 5.0 for your GPU and M.2 storage, and a platform that AMD has committed to supporting well into the future.

The onboard WiFi is solid (WiFi 6E rather than the newer WiFi 7, but still plenty fast for most home setups), and the 2.5Gb ethernet means wired connections are properly quick. You get two M.2 slots, which is enough for most builds, and the rear I/O is well stocked with USB 3.2 Gen 2 ports. The BIOS is clean and easy to navigate, which matters if you're not an experienced builder.

Power delivery is decent for a PRIME-series board. You won't be pushing extreme overclocks here, but for Ryzen 7000 and 9000 series chips running at stock or mild overclocks, it handles things without breaking a sweat. The board looks clean too. No garish RGB by default, though Aura Sync is supported if you want to add some lighting later.

Honestly, at this price point, it's hard to find a meaningful fault. It's not the flashiest board in this roundup, and it won't win any awards for raw feature count. But for a reliable, future-proof AM5 foundation that doesn't cost a fortune, it's the one we'd recommend to most people without hesitation.

Pros

  • AM5 platform with long-term AMD support
  • PCIe 5.0 ready for future GPUs and SSDs
  • Clean BIOS, easy to set up
  • WiFi 6E and 2.5Gb ethernet included
  • Sensible price for the feature set

Cons

  • Only two M.2 slots (some rivals offer three)
  • WiFi 6E rather than WiFi 7
  • Limited overclocking headroom compared to TUF or ROG boards

Best Overall Value (Budget Pick)

2. ASUS TUF GAMING X870-PLUS WIFI AMD ATX motherboard, 16+2+1(80A) power stages, DDR5, PCIe 5.0 w/ full support for next-gen GPUs, 4 x M.2 slots, WiFi 7, USB4, front USB 20Gbps w/ PD Fast Charge

Price: £249.99 | Rating: ★★★★☆ (4.4)

Four M.2 slots. WiFi 7. USB4. Front USB at 20Gbps with fast charging. On an X870 chipset. Under £240. That's a proper spec sheet for the money, and it's why this board earns its place as our best budget pick in the Best ASUS Motherboards Under £300 UK 2026 | 6 Tested roundup.

The X870 chipset sits above B850 in AMD's lineup, offering more PCIe lanes and better USB connectivity. In practice, that means you can run more high-speed storage devices simultaneously without bandwidth bottlenecks. The 16+2+1 power stage setup with 80A DrMOS components is genuinely impressive at this price. It means this board can handle even the most demanding Ryzen 9000 series chips without thermal throttling the VRMs.

WiFi 7 is a nice touch. Most boards at this price still ship with WiFi 6 or 6E, so getting WiFi 7 here is a genuine bonus if you have a compatible router. The front panel USB at 20Gbps with Power Delivery fast charging is also a thoughtful addition for anyone who charges phones or external drives from their PC regularly.

The TUF Gaming aesthetic is understated. It's not trying to look like a spaceship, which some people will appreciate. Build quality feels solid throughout. If you're building a high-performance AM5 system and want to keep costs sensible, this is the board to beat at this price.

Pros

  • X870 chipset with excellent PCIe lane allocation
  • Four M.2 slots for serious storage expansion
  • WiFi 7 included
  • USB4 and 20Gbps front USB with fast charging
  • Strong 16+2+1 power delivery

Cons

  • Pricier than B850 options
  • TUF aesthetic won't appeal to everyone
  • X870 features may be overkill for basic builds

3. ASUS TUF GAMING B850-PLUS WIFI AMD ATX motherboard, 14+2+1 80A DrMOS power stages, DDR5, PCIe 5.0 Ready, 3xM.2 slots, Wi-Fi 7, Realtek 2.5Gb Ethernet, DisplayPort, HDMI, USB 20Gbps Type-C, Aura Sync

Price: £176.32 | Rating: ★★★★½ (4.5)

The TUF Gaming range has always been about durability first, features second. And on the B850-PLUS WIFI, that philosophy holds up. Military-grade components, reinforced PCIe and memory slots, and a 14+2+1 power stage setup using 80A DrMOS components. This board is built to last, and it shows.

You get three M.2 slots (one more than the PRIME B850), WiFi 7, and a rear USB Type-C running at 20Gbps. The DisplayPort and HDMI outputs are useful if you're running integrated graphics temporarily or want a secondary display without a dedicated GPU. Aura Sync RGB is present but tasteful.

At around £260, it's the most expensive board in this roundup. But if you're the kind of person who keeps a PC for five or six years and wants to know the hardware underneath won't let you down, the TUF B850-PLUS WIFI justifies the premium. It's the board we'd recommend to anyone who prioritises longevity over raw feature count.

Pros

  • Military-grade TUF components for long-term reliability
  • Strong 14+2+1 80A power delivery
  • WiFi 7 and 2.5Gb ethernet
  • Three M.2 slots
  • DisplayPort and HDMI for iGPU use

Cons

  • Most expensive board in this roundup
  • B850 chipset rather than X870 at this price
  • Overkill for basic or budget builds

Best for Enthusiasts (AM4)

4. ASUS ROG STRIX B550-F GAMING (Wi-Fi) AMD Ryzen AM4 ATX motherboard (PCIe® 4.0, 14 power stages, WiFi 6, 2.5 Gb Ethernet, dual M.2, ASUS OptiMem II, AI Noise-Canceling MIC, USB 3.2 Gen 2 and Aura Sync)

Price: £146.02 | Rating: ★★★★½ (4.5)

Look, the ROG STRIX B550-F is a genuinely excellent board. But we need to be upfront: it's AM4, which means DDR4 memory and an ageing platform. If you already have a Ryzen 5000 series chip and a stack of DDR4 RAM, this board makes a lot of sense. If you're building from scratch in 2026, it's harder to justify.

That said, the feature set is impressive. Fourteen power stages, WiFi 6, 2.5Gb ethernet, dual M.2, and ASUS OptiMem II for better memory stability. The AI noise-cancelling microphone input is a nice touch for streamers or anyone on regular video calls. Aura Sync RGB is well implemented and the board looks properly premium.

At around £192, it's not cheap for an AM4 board. But if you're committed to the platform and want the best B550 experience ASUS offers, this is it. Just go in with eyes open about the platform's future.

Pros

  • Premium ROG feature set on B550

5. ASUS Prime B550M-A WiFi II Motherboard Review UK 2025

Price: £89.99 | Rating: ★★★★☆ (4.4)

For anyone building their first PC and feeling a bit overwhelmed, the ASUS Prime B550M-A WiFi II is a genuinely friendly starting point. It's Micro-ATX, so it fits in smaller cases. It has WiFi built in, so you don't need to faff about with adapters. And the ASUS BIOS is about as approachable as motherboard firmware gets.

Specs are modest. You get a single M.2 slot, four SATA ports, and USB 3.2 Gen 2 on the rear. It's AM4, so compatible with Ryzen 3000 through 5000 series chips. Not a board for enthusiasts, but that's not the point. For a first build, a home office machine, or a basic gaming rig, it does everything you need without overwhelming you with options.

Under £93 makes it accessible too. If you're new to PC building and want a board that won't fight you, this is a solid pick from our Best ASUS Motherboards Under £300 UK 2026 | 6 Tested selection.

Pros

  • Simple, beginner-friendly BIOS
  • WiFi included out of the box
  • Compact Micro-ATX form factor
  • Affordable price point

Cons

  • AM4 platform, limited future upgrade path
  • Only one M.2 slot
  • 1Gb ethernet rather than 2.5Gb
  • Limited overclocking support

6. Asustek computer PRIME A520M-K

Price: £51.73 | Rating: ★★★★½ (4.5)

The PRIME A520M-K is the no-frills option in this roundup. At around £54, it's the cheapest board here by some margin. And honestly, it shows. No WiFi, no 2.5Gb ethernet, no M.2 slot (just SATA storage), and the A520 chipset means no overclocking support at all. But here's the thing: for a basic office PC, a media centre, or a budget build where every pound counts, it does the job.

It's AM4, compatible with Ryzen 3000 through 5000 series chips. The BIOS is straightforward. Build quality is fine for the price. You're not getting anything exciting, but you're not paying for anything exciting either. If your use case is word processing, web browsing, and light media consumption, the A520M-K is perfectly adequate.

Just don't expect to game seriously on it or push any overclocks. It's a board for people who need a PC to work, not to impress.

Pros

  • Very affordable entry point
  • Compatible with Ryzen 3000 to 5000 series
  • Simple, reliable BIOS
  • Compact Micro-ATX form factor

Cons

  • No WiFi or Bluetooth
  • No M.2 slot
  • No overclocking support
  • 1Gb ethernet only
  • AM4 platform with no upgrade path

7. ASUS TUF GAMING B650M-PLUS AMD Ryzen AM5 Micro-ATX motherboard, 14 power stages, PCIe 5.0 M.2 support, DDR5 memory, 2.5 Gb Ethernet, USB4 support and Aura Sync

Price: £132.25 | Rating: ★★★★½ (4.6)

If you want AM5 in a smaller case, the TUF B650M-PLUS is the board to look at. Micro-ATX form factor, DDR5, PCIe 5.0 M.2 support, and USB4. That's a proper modern feature set squeezed into a compact package. The 14 power stages mean it can handle Ryzen 7000 and 9000 chips without issue, and the 2.5Gb ethernet is a welcome inclusion.

USB4 on a Micro-ATX board at this price is genuinely impressive. It opens up compatibility with Thunderbolt 4 peripherals and high-speed external storage. For a small form factor build that still needs to do serious work, this board delivers.

The main compromise is expansion. Fewer PCIe slots and M.2 slots than full ATX boards. But if you know you're building compact and don't need masses of storage, it's a smart choice from our Best ASUS Motherboards Under £300 UK 2026 | 6 Tested selection.

Pros

  • AM5 platform in Micro-ATX form factor
  • USB4 support
  • PCIe 5.0 M.2 ready
  • 14 power stages for solid performance

Cons

  • Fewer expansion slots than ATX boards
  • No onboard WiFi (check listing carefully)
  • B650 rather than B850 or X870

Best Mid-Range AM4

8. ASUS TUF Gaming B550-PLUS (WI-FI), AMD B550 (Ryzen AM4) ATX motherboard (PCIe 4.0, dual M.2, 10 DrMOS, DDR4 4400, Intel® WiFi 6, 2.5 Gb Ethernet, HDMI, DisplayPort, USB 3.2 Gen 2 Type-A and Type-C)

Price: £103.88 | Rating: ★★★★☆ (4.4)

The TUF B550-PLUS WiFi is a well-rounded AM4 board that hits a sensible price point. Ten DrMOS power stages, WiFi 6, 2.5Gb ethernet, dual M.2, and both HDMI and DisplayPort outputs. For anyone running a Ryzen 5000 series chip and not planning to upgrade the platform any time soon, it covers all the bases.

DDR4 support up to 4400MHz is decent for the platform. The TUF build quality is reassuring, and the BIOS is clean. It's not exciting, but it's reliable. At around £120, it's fair value for what you get, though the AM4 platform caveat applies here too.

Pros

  • WiFi 6 and 2.5Gb ethernet
  • Dual M.2 slots
  • HDMI and DisplayPort outputs
  • Solid TUF build quality

Cons

  • AM4 platform, limited future
  • DDR4 only
  • 10 power stages is modest for heavy overclocking

Best Aesthetics (AM4)

9. ASUS WAVE - ROG STRIX B550-A GAMING B550

Price: £119.99 | Rating: ★★★★½ (4.6)

The ROG STRIX B550-A GAMING is essentially a cleaner-looking version of the B550-F without the WiFi. If you're running a wired connection and want the ROG aesthetic without paying for wireless you won't use, this is the board. The styling is genuinely nice. Clean lines, subtle RGB, and the ROG branding that some builders specifically want in a windowed case.

Specs are solid for B550: PCIe 4.0, dual M.2, USB 3.2 Gen 2, and 2.5Gb ethernet. No WiFi is the obvious omission. At around £130, it's reasonable for what you get, though again, the AM4 platform question looms large for new builds in 2026.

Pros

  • Clean ROG aesthetic
  • 2.5Gb ethernet
  • Dual M.2 slots
  • Good USB connectivity

Cons

  • No WiFi
  • AM4 platform
  • ROG premium hard to justify in 2026 for AM4

Buy on Amazon£119.99

Best Compact AM4

10. 1200 ASUS TUF GAMING B550M-PLUS WIFI II

Price: £111.94 | Rating: ★★★★½ (4.6)

The TUF B550M-PLUS WIFI II is the compact AM4 option for anyone who wants TUF durability in a Micro-ATX package. WiFi is included, the power delivery is decent for a small board, and the B550 chipset means PCIe 4.0 support for your primary M.2 drive. It's a sensible choice for a small gaming build or a compact workstation running Ryzen 5000 series.

At around £127, it's not the cheapest Micro-ATX option, but the TUF build quality and WiFi inclusion justify the premium over the A520M-K. Just keep the AM4 platform limitations in mind.

Pros

  • Compact Micro-ATX with WiFi
  • TUF build quality
  • PCIe 4.0 M.2 support

Cons

  • AM4 platform
  • Fewer expansion options than ATX
  • Pricier than some alternatives

Best for Z370 Upgrades

11. ASUS ROG MAXIMUS XI HERO LGA1151 DDR4 DP HDMI M.2 Z370 ATX Motherboard - Black

Price: £199.00 | Rating: ★★★★½ (4.6)

We'll be straight with you: the ROG MAXIMUS XI HERO is a premium board for a platform (LGA1151, Z370) that Intel stopped supporting years ago. At £220, it's genuinely difficult to recommend for a new build. The only scenario where this makes sense is if you already have a compatible Intel 8th or 9th gen chip and want to upgrade your board without replacing the CPU.

The board itself is excellent quality. ROG MAXIMUS series has always been ASUS's flagship, and the build quality here is exceptional. But the platform is a dead end. For new builds in 2026, look at the AM5 options in this roundup instead. This one earns its place here purely for existing Z370 system owners.

Pros

  • Exceptional ROG build quality
  • Good for existing LGA1151 system upgrades
  • M.2 and full ATX feature set

Cons

  • Dead platform, no upgrade path
  • Expensive for what it is in 2026
  • DDR4 only, Intel LGA1151 only
  • Not recommended for new builds

Frequently Asked Questions

The ASUS TUF Gaming B550-PLUS offers the best overall value, with PCIe 4.0 support, dual M.2 slots, and solid VRM cooling. For those wanting the latest AM5 platform, the TUF Gaming B650-PLUS WIFI provides DDR5 support and built-in WiFi, making it ideal for future-proof gaming builds.

AM5 is the better choice for new builds in 2026, offering DDR5 support and a longer upgrade path. However, AM4 boards like the B550-PLUS remain excellent value if you already own compatible Ryzen CPUs or want to save money on DDR4 RAM. AM4 is essentially end-of-life but still performs brilliantly for gaming.

Only the B850 chipset boards (ROG Strix B850-E and B850-A) offer PCIe 5.0 x16 slots. The B550 and B650 models max out at PCIe 4.0, which is still more than adequate for current GPUs and NVMe drives. Unless you're planning to use cutting-edge PCIe 5.0 SSDs, PCIe 4.0 won't bottleneck your system.

ROG Strix boards typically offer better VRM designs, more premium aesthetics, enhanced RGB lighting, and additional features like better audio codecs. TUF Gaming focuses on durability and value, with military-grade components and solid performance at lower prices. For most gamers, TUF Gaming provides everything needed without the premium price tag.

Two M.2 slots cover most users comfortably (one for OS, one for games/storage). The B850 boards offer 4-5 M.2 slots, which is brilliant for content creators or those running multiple high-speed drives. Budget boards with 2 slots are perfectly adequate for gaming, and you can always add SATA SSDs if needed.
