MSI PRO B650M-P Motherboard Review UK 2026

Pick the wrong motherboard and you’ll spend the next five years dealing with BIOS crashes, random reboots, and USB ports that work when they fancy it. I’ve seen enough botched builds to know this firsthand. The MSI PRO B650M-P sits at the absolute bottom of the AM5 pricing ladder, which makes it either a brilliant budget find or a false economy waiting to happen. After several weeks of testing with everything from a Ryzen 5 7600 to a power-hungry 7900X, I can tell you exactly what you’re getting for under £120.

The B650 chipset is AMD’s mainstream option, which means you get CPU overclocking support (unlike Intel’s locked B-series chipsets) and proper DDR5 memory overclocking. No PCIe 5.0 for storage, but honestly? That’s not a real-world problem yet. PCIe 4.0 NVMe drives are still faster than anything most people will ever need.

What you’re getting here is the GPU running at full PCIe 5.0 x16 speed (from the CPU directly), which matters for future graphics cards. Storage and everything else runs through PCIe 4.0, which is still plenty fast. The board supports EXPO memory profiles, which is AMD’s version of Intel’s XMP. Works exactly the same way.

Right, let’s talk about what actually matters. This board uses an 8+2+1 phase design with 50A power stages. That’s eight phases for the CPU cores, two for the SOC, and one for memory. Not impressive on paper, but MSI’s done something clever here. They’ve actually put a proper heatsink on the VRM instead of the decorative aluminium foil you see on some budget boards.

During testing with a Ryzen 7 7700X (105W TDP), VRM temperatures stayed around 68°C under sustained Cinebench loads. That’s perfectly acceptable. Push it with a 7900X and you’re looking at mid-70s, which is warm but not dangerous. I wouldn’t run a 7950X on this board long-term, though. You can, but why stress the components?

The heatsink makes contact with all the power stages. I’ve seen budget boards where the heatsink is just decorative plastic. This one actually does its job. There’s no heatpipe connecting to the chipset (because there isn’t really a chipset heatsink), but the B650 chipset barely gets warm anyway.

One thing that annoyed me: the 8-pin EPS power connector is right at the top edge of the board, which is good, but there’s no second 4-pin connector. You don’t need one for mid-range CPUs, but it would’ve been nice for people who upgrade later. Then again, at this price point, you’re not buying this for a 7950X3D.

This is where MSI pulls ahead of some competitors. The BIOS is the same Click BIOS 5 interface you get on their premium boards. It’s not dumbed down or missing features. You get proper fan curve control, easy EXPO profile selection, and a search function that actually finds settings.

Fan control deserves specific mention because most budget boards completely botch this. You get four fan headers total (one CPU, three chassis), and you can set individual curves for each. The curves are responsive too. Set a 60°C target and the fans actually ramp at 60°C, not 65°C like some boards I’ve tested.

Memory overclocking works but don’t expect miracles. EXPO profiles loaded fine with my DDR5-6000 kit. Manual tuning is possible but the board isn’t going to push DDR5-7000+ like premium boards do. For 99% of users, enabling EXPO and forgetting about it is the right move anyway.

BIOS updates are straightforward. MSI’s M-Flash utility works from a USB stick, no Windows installation required. I updated to the latest AGESA firmware without issues. The board shipped with an older BIOS but it supported my 7700X out of the box.

The board officially supports up to DDR5-6400 with overclocking, but I had no problems running DDR5-6000 EXPO profiles. That’s the sweet spot for Ryzen 7000 anyway. Going faster gives you maybe 2-3% more performance while costing significantly more. Not worth it.

One quirk: the DIMM slots don’t have the reinforced metal shields you see on premium boards. They’re standard plastic. I’ve never actually seen a DIMM slot break from normal use, but if you’re the type who rams components in without reading the manual, be gentle here.

Storage is where budget boards make their compromises, and this one’s no different. You get two M.2 slots, both PCIe 4.0 x4. No PCIe 5.0 storage support, but as I said earlier, that’s not a real limitation yet. Both slots have basic heatsinks. They’re thin aluminium but they do drop temperatures by about 8-10°C compared to running bare.

Here’s the annoying bit: the second M.2 slot shares bandwidth with the bottom PCIe slot and two of the SATA ports. Use the second M.2 and you lose SATA ports 3 and 4. Use a card in the bottom PCIe slot and the second M.2 drops to x2 speed. This is chipset lane sharing and it’s normal for budget boards, but you need to plan your storage layout.

Four SATA ports is adequate for most builds. If you’re running multiple mechanical drives for storage, you’ll need to be strategic about which M.2 slots you use. For a typical gaming build with one NVMe boot drive and maybe one SATA SSD for games, you’re fine.

The rear I/O is functional but nothing special. You get one USB-C port (10Gbps), which is the minimum acceptable in 2026. Two more USB 3.2 Gen 2 Type-A ports for fast peripherals. Then two USB 3.2 Gen 1 and two USB 2.0 ports for mice, keyboards, and other low-speed devices.

No WiFi. You’ll need a PCIe card or USB adapter if you can’t run ethernet. The 2.5GbE port is Realtek, which works fine but isn’t as low-latency as Intel NICs. For gaming it makes no practical difference.

Audio is Realtek ALC897, which is MSI’s polite way of saying “basic audio codec”. It’s fine for headphones and desktop speakers. If you’re running studio monitors or expensive headphones, you’ll want a DAC. But most people won’t notice the difference from premium codecs.

The ASUS PRIME B650M-A costs more but adds WiFi 6 (in the AX variant) and ASUS’s BIOS, which some people prefer. The VRM is similar, connectivity is similar. If you need WiFi, the ASUS makes sense. If you don’t, you’re paying for a feature you won’t use.

Compared to stepping up to a B650 board with better VRMs and more features, you’re looking at £150-180. That extra money gets you better power delivery for high-end CPUs, more USB ports, sometimes WiFi 6E, and PCIe 5.0 M.2 support. Worth it if you’re running a 7900X or want maximum future-proofing. Not worth it for a Ryzen 5 or 7600X build.

The 24-pin power connector is in the middle-right of the board, which means your cable will stretch across the motherboard in most cases. Not ideal for aesthetics but functionally fine. The 8-pin EPS is top-left, which is standard.

M.2 installation is tool-free, which I appreciate. You slide the drive in, push down the little plastic retention clip, and you’re done. The heatsinks are held on with small screws and thermal pads are pre-applied. Don’t lose the screws.

One minor annoyance: the CMOS clear jumper is tucked between the bottom PCIe slot and the edge of the board. If you need to clear CMOS with a GPU installed, you’ll need to remove the GPU first. There’s also a CMOS clear button on the rear I/O, which partially solves this.

The question with any budget board is: what did they cut to hit this price? With the MSI PRO B650M-P, the cuts are sensible. No WiFi (add your own if needed). Only two M.2 slots (most people use one). Basic audio codec (fine for 90% of users). VRM that’s adequate for mid-range CPUs but not flagship chips (which is exactly what budget builders are running).

What they didn’t cut: BIOS quality, VRM cooling, USB-C support, or build quality. The PCB feels solid, components are properly mounted, and nothing feels like it’ll fail in 18 months. That’s what separates a good budget board from a false economy.

Compared to Intel’s B760 boards at similar prices, you’re getting CPU overclocking support (which Intel locks behind Z790) and a platform with a longer promised support window. AMD’s committed to AM5 through 2027, so you can drop in a Ryzen 8000 or 9000 series chip when you’re ready to upgrade.
