Gigabyte B650 Gaming X AX V2 Motherboard Review UK 2026

Look, I’ve tested a lot of motherboards. And I mean a lot. But here’s what most reviews won’t tell you: specs on a box don’t mean anything if the board throttles your CPU because the VRM is rubbish, or if the BIOS makes you want to throw your keyboard through the window. So when I got my hands on the Gigabyte B650 Gaming X AX V2, I wasn’t interested in just running benchmarks. I wanted to know if this thing actually holds up when you’re building a proper system that needs to work reliably for the next five years.

Here’s where AMD gets it right. Unlike Intel’s habit of changing sockets every other generation, AM5 is actually a platform you can build on. I’ve installed both Ryzen 7000 and newer 8000 series chips on this board during testing, and everything just works. No BIOS gymnastics, no compatibility headaches.

The B650 chipset sits in that sweet spot where you get the features that actually matter without paying for stuff you’ll never use. You get PCIe 5.0 support for your primary M.2 slot (which is brilliant for future storage upgrades), CPU overclocking support, and proper memory overclocking with both AMD EXPO and Intel XMP profiles.

What you don’t get is the extra PCIe 5.0 lanes for your GPU that X670E boards offer. But honestly? There’s not a single GPU on the market in 2026 that saturates PCIe 4.0 x16, so you’re not losing anything practical.

Right, this is where I get picky. Because VRM quality is the difference between a motherboard that lasts five years and one that thermal throttles after eighteen months.

Gigabyte has gone with an 8+2+2 direct phase design here. That’s eight phases for the CPU cores, two for the SOC, and two for memory. Each phase uses 60A power stages, which gives you 480A of total current capacity for the CPU. For context, even a power-hungry Ryzen 9 7950X draws around 230A under full load. You’ve got headroom.

But here’s what matters more than the numbers: the heatsink design. Gigabyte has used a chunky aluminium heatsink with proper surface contact on the MOSFETs. It’s not just a decorative piece of metal screwed on top. During my testing with a Ryzen 7 7800X3D running Cinebench R23 loops, the VRM temps stayed impressively cool.

Tested with Ryzen 7 7800X3D, Noctua NH-D15, 22°C ambient temperature. Extended stress testing (30-minute Cinebench loops) showed zero throttling. VRM temps are excellent for this price bracket.

I’ve seen boards in the mid-range segment hit 80°C+ under similar conditions. That’s when you start getting voltage droop and potential long-term reliability issues. 62°C is proper thermal management.

I’m not going to lie to you. Gigabyte’s BIOS isn’t as polished as ASUS’s or as feature-rich as MSI’s. But you know what? It works, and it doesn’t get in your way.

The Easy Mode gives you the basics: boot priority, fan speeds, EXPO/XMP profiles. That’s all most people need. Switch to Advanced Mode and you get access to voltage controls, LLC settings, and all the overclocking options without the interface trying to be clever.

Fan control is straightforward. You get individual curves for each header, and they actually respond properly. I set up a custom curve for my case fans that keeps things quiet at idle and ramps up under load. No weird behaviour, no fans spinning up and down constantly like some boards do.

Where it falls short is advanced memory tuning. If you’re the type who wants to manually tweak subtimings and play with VSOC voltage, you’ll find the options a bit limited. For most people running EXPO profiles though? It’s fine. I tested with Corsair Vengeance DDR5-6000 and G.Skill Trident Z5 DDR5-6400, both worked perfectly with their EXPO profiles enabled.

The board officially supports up to DDR5-6400 with overclocking, but I’ve seen people push DDR5-7200 kits on this board with the right memory ICs. Your mileage will vary depending on your CPU’s memory controller quality (it’s a lottery with Ryzen chips) and your RAM kit.

During testing, I ran DDR5-6000 CL30 without any issues. That’s the sweet spot for Ryzen 7000 series anyway. You get the 1:1 Infinity Fabric ratio and good performance without paying silly money for faster kits that don’t deliver proportional gains.

Four DIMM slots means you can start with 32GB (2x16GB) and expand later. The slots are properly spaced, so even with a massive CPU cooler like the NH-D15, you can access all four slots without removing the cooler. Small detail, but it matters when you’re actually building.

Three M.2 slots is the minimum I’d accept on a modern motherboard, and Gigabyte has configured them sensibly. The primary M.2 slot (closest to the CPU) is PCIe 5.0 x4, which means you’re ready for the next generation of SSDs that’ll actually saturate PCIe 4.0.

All three M.2 slots have thermal pads and heatsinks. The top slot has a chunky heatsink that’s properly mounted. I tested with a Samsung 990 Pro (PCIe 4.0 drive) and temps stayed at 54°C under sustained writes. That’s proper cooling, not just decorative metal.

You also get four SATA ports, which is becoming rare on modern boards. If you’ve got old HDDs or SATA SSDs lying around, you can still use them. The ports are sensibly placed at the board edge, so cable routing is straightforward.

The rear I/O is properly equipped. You get a good spread of USB ports including a Type-C port at 10Gbps. The WiFi 6E implementation uses a MediaTek MT7922 chip, which is solid. I tested wireless speeds and got consistent 900+ Mbps on my WiFi 6 router. Latency was stable for gaming.

The 2.5GbE ethernet is Realtek-based rather than Intel, which some people complain about. But in real-world testing, it works fine. I’ve had zero connection drops or stability issues during several weeks of testing.

The ASUS TUF is slightly cheaper and has ASUS’s excellent BIOS, but it’s only WiFi 6 (not 6E) and the VRM runs a bit warmer under sustained loads. For similar money, the Gigabyte offers better thermal performance.

If you’re looking at other options in the B650 space, the Gigabyte B650 Eagle AX is worth considering if you want to save a bit more, though you lose some connectivity. The B650 AORUS Elite AX sits above this in Gigabyte’s range with slightly better VRM cooling and more RGB headers if that matters to you.

The integrated I/O shield is a godsend. No more fiddly separate shields that fall out when you’re trying to mount the board. It’s already attached, properly aligned, and has decent padding so you don’t scratch your ports during installation.

Front panel headers (power button, reset, LEDs) are clearly labelled and positioned at the bottom right corner where they should be. The RGB headers are spread around the board, so you can route cables cleanly regardless of where your RGB stuff lives.

My only minor gripe is the USB 3.0 header placement. It’s functional, but if you’re using a chunky 24-pin power cable, you might need to route it carefully. Not a dealbreaker, just something to be aware of.

This is where the B650 Gaming X AX V2 really shines. It delivers the features that actually impact your daily experience (solid VRM, WiFi 6E, PCIe 5.0 storage, good connectivity) without wasting money on stuff that looks good in marketing but doesn’t matter in practice.

Compare it to budget boards in the under £120 segment, and you’ll find they typically use weaker VRMs that’ll struggle with higher-end CPUs, lack WiFi entirely, or only offer WiFi 5. Step up to upper mid-range boards above £180, and you’re mostly paying for extra M.2 slots you probably won’t use, premium audio codecs that sound identical to cheaper ones through most headphones, or elaborate RGB lighting systems.

For someone building a Ryzen 7 7700X or 7800X3D system with a mid-range GPU, this board gives you everything you need and nothing you don’t. That’s proper value.

If you’re building a Ryzen 7000 or 8000 series system and your budget sits in the mid-range bracket, this board should be on your shortlist. It’s not the cheapest option, but the extra money over budget boards buys you VRM quality and features that’ll matter for years. It’s not the most expensive either, which means you’re not paying for premium features you’ll never use.

The over 2,600 verified reviews averaging 4.5 stars tell you this isn’t just my opinion. People are building with this board, and it’s working reliably. That’s what matters.
