ASUS TUF GAMING X870-PLUS WIFI Review UK 2026

Motherboards fail in two ways. Either they die spectacularly within the first six months, or they quietly limit your system for years without you realising it. The difference comes down to VRM quality, chipset capabilities, and whether the manufacturer cut corners where it matters. After testing the ASUS TUF Gaming X870-PLUS WiFi for about a month with various Ryzen 9000 CPUs, I’ve got data on which category this board falls into.

The X870 chipset is AMD’s current flagship offering, and it’s basically two X670 chipsets linked together. Sounds wasteful, but it gives you proper USB4 support and more PCIe lanes than B650. Here’s what that actually means in practice.

The CPU provides 24 PCIe 5.0 lanes directly. Sixteen go to your graphics card, four go to the primary M.2 slot, and four connect to the chipset. The X870 chipset then provides twelve PCIe 4.0 lanes for the remaining M.2 slots, SATA ports, and additional USB controllers. It’s a sensible setup that doesn’t force you to choose between storage and expansion cards.

One thing worth noting: X870 mandates USB4 support, which is why this board has a proper 40Gbps USB4 port on the rear I/O. Most B650 boards skip USB4 entirely. Whether you need 40Gbps USB is debatable, but if you’re connecting fast external SSDs or Thunderbolt peripherals, it’s there.

Let’s talk numbers. The VRM uses sixteen 80A power stages for the CPU VCore, two stages for the SoC, and one for VDDIO. ASUS partnered with their usual suppliers (likely Vishay SiC840 or equivalent MOSFETs based on the thermal performance I measured). The heatsinks are chunky aluminium with proper thermal pad contact.

I tested VRM thermals with a Ryzen 9 9950X running Cinebench R23 multi-core for 30 minutes in a case with mediocre airflow (two intake fans, one exhaust). Ambient temperature was 22°C. VRM temperatures stabilised at 62°C. That’s excellent. For context, budget boards with 10-phase VRMs hit 85-90°C under the same load.

The 16-phase design means each stage handles roughly 10.6A when the 9950X pulls 170W (assuming 1.2V VCore). With 80A rated stages, you’re running at 13% of maximum capacity per phase. This matters for two reasons: efficiency peaks at low load percentages, and component longevity increases dramatically when you’re not pushing limits.

I also tested with PBO (Precision Boost Overdrive) enabled, letting the 9950X pull up to 230W during all-core workloads. VRM temps climbed to 68°C. Still well within safe operating range. The heatsinks never got hot enough to warrant additional cooling, though having a case fan blowing across the VRM area obviously helps.

One detail I appreciate: ASUS positioned the 8-pin and 4-pin CPU power connectors at the top-left edge of the board. Easy cable routing, no interference with RAM or coolers. Sounds basic, but I’ve tested boards where the connectors are positioned like the engineer never actually built a PC.

The BIOS uses ASUS’s standard UEFI interface. It’s not the ROG BIOS with all the overclocking features, but it’s competent. EZ Mode gives you the basics (boot order, EXPO/XMP, fan curves). Advanced Mode provides access to voltage controls, PBO settings, and memory timing adjustments.

Fan control deserves specific mention because ASUS historically made this unnecessarily complicated. The TUF Gaming X870-PLUS WiFi lets you set custom curves for each header using a simple graph interface. You can base curves on CPU temperature, motherboard temperature, or specific sensor readings. It works as it should. Finally.

Memory overclocking is where the BIOS shows its mid-range positioning. EXPO profiles up to DDR5-6000 loaded instantly on my G.Skill Trident Z5 kit. Manual tuning is possible but you don’t get the extensive sub-timing controls that ROG boards offer. For most builders, this doesn’t matter. If you’re chasing DDR5-7200+ with manually tuned timings, you’re probably looking at ROG boards anyway.

BIOS updates are handled through EZ Flash 3, which lets you update from a USB drive or download directly via internet connection. I updated to BIOS version 1403 (released December 2025) without issues. The update added improved memory compatibility and refined PBO behaviour for Ryzen 9000X3D chips.

I tested three memory kits: G.Skill Trident Z5 DDR5-6000 CL30 (32GB), Corsair Vengeance DDR5-6400 CL32 (32GB), and Kingston Fury Beast DDR5-5600 CL36 (32GB). All three loaded their EXPO profiles without requiring manual intervention. The G.Skill kit ran at its rated 6000MHz with 30-38-38-96 timings and 1.35V. Zero stability issues during memory stress testing with TM5 and OCCT.

Maximum capacity is 192GB using four 48GB modules. That’s relevant if you’re running virtual machines or doing serious content creation work. For gaming, 32GB (2x 16GB) is the sweet spot. Populate slots A2 and B2 (the second and fourth slots from the CPU) for optimal memory performance with two modules.

One quirk: Ryzen 9000 chips prefer DDR5-6000 with a 1:1:1 memory controller ratio (MCLK:FCLK:UCLK all synchronised). Running faster memory often requires decoupling the Infinity Fabric clock, which can hurt performance in some workloads. The BIOS handles this automatically when you enable EXPO, but it’s worth understanding if you’re manually tuning.

Four M.2 slots is generous for this price bracket. The primary slot (M.2_1) connects directly to the CPU with PCIe 5.0 x4 bandwidth. That’s 128Gbps theoretical, though no consumer SSDs saturate that yet. The remaining three M.2 slots run PCIe 4.0 x4 through the chipset.

All four M.2 slots support drives up to 80mm length (M.2 2280 standard). Each slot includes an aluminium heatsink with thermal pad. During testing, my WD Black SN850X (PCIe 4.0 drive) maintained 62°C under sustained write loads in the M.2_2 position. That’s acceptable, though not exceptional. The heatsinks do their job.

The board also provides four SATA 6Gbps ports. That’s down from the six ports you’d find on older platforms, but realistically most builders are using M.2 drives now. Four SATA ports handles a couple of mechanical hard drives for bulk storage without issue.

PCIe slot layout is sensible. The primary x16 slot sits at the top (PCIe 5.0 from CPU). The second x16 slot (electrically x4, PCIe 4.0) sits three slots down, giving you proper clearance for dual-slot graphics cards plus a capture card or sound card. The single x1 slot sits at the bottom. No weird spacing issues that force you to choose between expansion cards.

The rear I/O is comprehensive. That single USB4 port delivers 40Gbps and supports DisplayPort Alt Mode plus USB Power Delivery up to 27W. Useful if you’re connecting Thunderbolt docks or fast external SSDs. The four USB 3.2 Gen 2 ports (the 10Gbps ones) handle most peripherals. I appreciate that ASUS included proper labelling on the I/O shield.

WiFi 7 uses Intel’s BE200 module. It’s proper WiFi 7 with 320MHz channel support and 5.8Gbps theoretical maximum. Real-world performance depends entirely on your router, but I measured 1.2Gbps download speeds on my WiFi 6E network (limited by my internet connection, not the WiFi module). The antennas mount via standard RP-SMA connectors if you want to upgrade them.

Network connectivity uses Intel’s I226-V 2.5GbE controller. It’s reliable and widely supported in Windows and Linux. If you’ve got a 2.5GbE switch or router, you’ll actually use that bandwidth. Otherwise, it’s backwards compatible with standard gigabit networks.

The MSI Tomahawk offers an extra M.2 slot (five total versus four) and MSI’s Click BIOS 5, which is genuinely the best BIOS interface currently available. But the VRM is slightly weaker (14-phase at 75A versus 16-phase at 80A). For most builds, this difference is academic. For sustained all-core workloads on a 9950X, the ASUS board runs 4-6°C cooler.

Gigabyte’s Aorus Elite WiFi typically costs slightly less and offers similar features on paper. The 16+2+2 VRM uses 70A stages, giving you 1,120A total versus the TUF’s 1,280A. The practical difference? About 5°C higher VRM temps under heavy load. Gigabyte’s BIOS is functional but less polished than ASUS or MSI. If you’re saving money, it’s a reasonable alternative.

Where the ASUS board pulls ahead: VRM thermal performance, build quality (the PCB feels more substantial), and the number of rear USB 10Gbps ports. Where it falls behind: BIOS sophistication compared to MSI, and it costs slightly more than the Gigabyte option.

The 24-pin ATX power connector sits at the right edge of the board where it belongs. The 8-pin and 4-pin CPU power connectors are at the top-left. Cable routing worked cleanly in every case I tested (Fractal Design Torrent, Lian Li Lancool 216, and Corsair 4000D). No awkward reaches or cables stretching across components.

Front panel headers are labelled directly on the PCB. The USB 3.2 Gen 1 header (the standard front panel USB 3.0 connector) sits at the bottom-right edge. The USB 3.2 Gen 2 front panel header (for cases with USB-C) sits just above it. RGB headers are positioned at the top and bottom edges. Sensible placement that doesn’t force you to route cables across the motherboard.

One minor annoyance: the second M.2 slot (M.2_2) sits directly under where most graphics cards end. If you’ve got a thick GPU installed and need to swap the M.2 drive in that slot, you’ll need to remove the graphics card first. Not a dealbreaker, but worth knowing.

The value proposition comes down to this: you’re getting VRM quality and connectivity that matches boards costing £80-100 more, but without the premium board tax for features like RGB everywhere, debug LEDs, and extreme overclocking support. If you’re building a Ryzen 9000 system and want WiFi 7, USB4, and four M.2 slots, you’d struggle to find better value in the X870 chipset range.

Compared to B650 boards in the mid-range bracket (£120-180), you’re paying extra for USB4, WiFi 7 instead of WiFi 6E, and better VRM cooling. Is that worth it? Depends on your build. If you’re running a Ryzen 5 or Ryzen 7 chip and don’t need WiFi 7, B650 boards offer identical gaming performance for less money. But if you’re building around a Ryzen 9 chip or want the connectivity features, the price difference is justified.

Against premium X870E boards (the enthusiast tier above £280), you’re missing features like additional PCIe 5.0 M.2 slots, 10GbE networking, and more elaborate BIOS options. For most builders, those features don’t translate to measurable performance differences. You’re paying for bragging rights and future-proofing that may never matter.

For Ryzen 9 9900X or 9950X builders who want WiFi 7 and USB4 built-in, this board makes sense. For budget Ryzen 5 builds, you’d be overpaying for features you don’t need. And for extreme overclockers, ROG boards offer more granular control. But for the majority of upper mid-range builds, the TUF Gaming X870-PLUS WiFi hits the right balance.
