ASUS ROG Strix X670E-F Review UK 2026: Rated

I've been building PCs long enough to know that picking the wrong motherboard isn't just annoying. It's expensive. You'll either bottleneck a brilliant CPU, deal with dodgy BIOS updates for years, or watch your system throttle because someone decided to save 50p on VRM heatsinks. And at the premium end of the market, you'd think this wouldn't be an issue. Spoiler: it still is.

The ASUS ROG Strix X670E-F Gaming WiFi sits in that awkward spot where you're paying flagship money but not quite getting the flagship board. After several weeks of testing with various Ryzen 7000 chips, I've got strong opinions about whether it's worth your cash.

Here's what matters: X670E isn't just marketing letters. The 'E' means you get PCIe 5.0 lanes split between your GPU slot and primary M.2 slot, both running directly from the CPU. X670 (non-E) boards make you choose. This is the full experience.

The X670E chipset is actually two X670 chipsets working together, which sounds daft but gives you genuinely useful connectivity. Five M.2 slots isn't overkill when you're running a game library, work files, and scratch disks. Four SATA ports feels a bit stingy though, especially when cheaper boards offer six.

Right, this is where I get picky. I've tested too many "premium" boards with rubbish VRMs dressed up in RGB. The Strix X670E-F doesn't play that game.

Eighteen power stages for the CPU, each rated for 110A. That's 1,980A of theoretical current delivery, which is frankly absurd (and you'll never use it). But what matters is efficiency. More phases means each one works less hard, generates less heat, and lasts longer. I ran a 7950X with PBO enabled for hours during testing. VRM temps peaked at 58°C under sustained Cinebench loads. That's brilliant.

The heatsinks are chunky aluminium with proper thermal pads, not the thin rubbish you get on budget boards. They're also screwed down, not clipped. Small detail, but it matters when you're moving your PC around.

ASUS's "ProCool II" power connectors (that's an 8+4 pin CPU power setup) are overbuilt for most users, but if you're planning extreme overclocking, they're there. For normal use, even with a 7950X, the 8-pin alone is fine.

One gripe: the VRM heatsink covers the top M.2 slot's heatsink, making it fiddly to access if you need to swap drives later. Not a dealbreaker, just annoying.

Look, most BIOS interfaces are terrible. ASUS's is merely okay, which makes it one of the best by default. That's a low bar.

The EZ Mode dashboard shows temps, voltages, and fan speeds clearly. You can enable XMP (sorry, AMD calls it EXPO now) with one click. Job done for most people.

Advanced Mode is where enthusiasts live. The layout is logical: Ai Tweaker for overclocking, Advanced for hardware config, Monitor for sensors, Boot for... well, boot options. Nothing's hidden in weird submenus like some manufacturers do.

Fan control is excellent. Six fan headers (four PWM, two AIO), all individually configurable with custom curves. The Q-Fan tuning wizard actually works, though I still prefer setting curves manually. You can link fans to specific temp sensors (CPU, VRM, chipset), which is brilliant for targeted cooling.

Memory overclocking is straightforward. EXPO profiles loaded first time for my DDR5-6000 kit. Manual tuning is there if you want it, with all the sub-timings accessible. ASUS's MemTest integration is handy for stability testing without rebooting to Windows.

The "AI" features are mostly marketing. AI Cooling adjusts fan curves automatically based on usage patterns. It's fine, but I'd rather set my own curves. AI Networking supposedly prioritizes gaming traffic, but I couldn't measure any real difference. AI Overclocking is just auto-PBO with extra steps.

BIOS updates have been stable so far. ASUS's USB BIOS Flashback works without needing a CPU installed, which is proper useful if you're building with a newer Ryzen chip that needs a firmware update.

Four DIMM slots means you can start with 32GB and upgrade to 128GB later if you need it. The slots are properly spaced, so even massive heatspreaders don't interfere with the first PCIe slot.

Memory overclocking is solid. I pushed the DDR5-6000 kit to 6200MHz stable with slightly tighter timings. Nothing record-breaking, but that's more about the memory chips than the board. The trace layout is good (daisy-chain topology), which helps with stability at higher speeds.

One thing to note: Ryzen 7000's memory controller is the limiting factor, not the motherboard. Don't expect miracles beyond DDR5-6400 unless you're running a golden sample CPU with expensive B-die equivalent DDR5.

Five M.2 slots is genuinely useful, not just spec sheet padding. The first one (under the VRM heatsink) is PCIe 5.0 x4, ready for upcoming 14GB/s drives. The other four are PCIe 4.0 x4, which is still 7GB/s each. All have integrated heatsinks that actually work. I measured a 15°C drop on a Gen4 drive under load compared to running bare.

Four SATA ports feels stingy for a premium board. If you're migrating from an older system with multiple HDDs, you might need a PCIe SATA adapter. Annoying but not uncommon at this tier.

Rear I/O is comprehensive. The 20Gbps USB-C is brilliant for external NVMe enclosures. Four 10Gbps ports means you're not constantly swapping cables. The two USB 2.0 ports are perfect for keyboards and mice (lower latency, less overhead).

2.5GbE is the sweet spot for home networks. Fast enough to saturate most NAS setups, compatible with gigabit switches. WiFi 6E adds 6GHz band support, though you'll need a WiFi 6E router to use it. I got 940Mbps on my 1Gbps connection over WiFi, which is proper impressive.

Internal headers are well-placed. Two USB 3.2 Gen 1 headers (four ports total), one USB 3.2 Gen 2 Type-C header for front panel. Three RGB headers (two addressable, one standard). Eight fan headers total across the board. You won't run out of connectivity.

The MSI Carbon WiFi is slightly cheaper and offers more SATA ports, which matters if you're keeping older drives. But its VRM runs hotter under sustained load (I've tested it), and the BIOS isn't as polished.

The Gigabyte Aorus Master costs more but gives you two PCIe 5.0 M.2 slots and eight SATA ports. If you need maximum storage connectivity, it's worth the premium. Otherwise, you're paying for features you won't use.

The Strix X670E-F sits in the sweet spot: proper VRM, good connectivity, and ASUS's better BIOS experience. You're not overpaying for features or compromising on the bits that matter.

The M.2 installation is tool-free for the first three slots (slide-in mounting), which is brilliant. The last two slots use traditional screws. All the heatsinks come pre-installed, so you just slot the drive in and secure it.

One annoyance: the top USB 3.0 header sits right next to the 8-pin CPU power connector. If you're using a chunky PSU cable or custom sleeving, it's a tight fit. Not impossible, just fiddly.

The Q-LED diagnostic lights are actually useful. Four LEDs (CPU, DRAM, VGA, BOOT) tell you exactly where the POST process failed. Saved me twenty minutes troubleshooting a loose RAM stick during testing.

RGB is everywhere if you're into that. I'm not, but at least ASUS lets you turn it all off in BIOS. The Aura Sync software works if you want synchronized lighting across components, though I'd rather not install extra software.

The SATA port complaint is the most common legitimate gripe. Four ports is stingy for a premium board. MSI and Gigabyte offer more at similar price points.

Some users reported early BIOS versions had stability issues with certain RAM kits, but that's been sorted in recent updates. Always update to the latest BIOS before installing your OS.

Right, let's talk money. This board sits firmly in the premium category, and for once, you're getting what you pay for.

Compared to upper mid-range boards (the B650E and lower-end X670 options), you're getting significantly better VRM components. That matters if you're running a 7900X or 7950X. Cheaper boards will work, but they'll run hotter and potentially throttle under sustained loads. The power delivery here is genuinely premium.

The PCIe 5.0 support across both GPU and primary M.2 slot is the other premium feature. B650E boards only give you PCIe 5.0 on the GPU slot. X670 (non-E) makes you choose. X670E gives you both. Whether that matters depends on how long you keep your system. PCIe 5.0 GPUs are coming, and PCIe 5.0 SSDs are already here.

Five M.2 slots with proper heatsinks isn't common in lower tiers. Neither is WiFi 6E or 2.5GbE. You can find cheaper boards with some of these features, but not all of them with this level of execution.

Where it falls short: only four SATA ports, and the BIOS AI features are mostly marketing fluff. Neither is a dealbreaker, but they're worth noting.

If you're building around a Ryzen 5 7600X, this board is overkill. Get a B650 board and save your money for a better GPU. But if you're running a 7900X or higher, the premium you pay here prevents throttling and gives you proper upgrade headroom.

You're paying premium money, but you're getting premium features and execution. That's rarer than it should be in this market.
