MSI PRO X870E-P WIFI Motherboard Review: High-Performance AMD AM5 Platform

Building a Ryzen 9000 system means choosing between 47 different AM5 motherboards. Each manufacturer claims theirs is the one you need. After testing the MSI PRO X870E-P WIFI for three weeks alongside competing boards, I’ve got the numbers that actually matter. The X870E chipset promises full PCIe 5.0 support and USB4 connectivity, but whether MSI’s implementation delivers at this price point is what we’re here to determine.

The X870E chipset is AMD’s current flagship platform controller. Unlike B650 boards that often compromise on PCIe lane allocation, X870E guarantees full PCIe 5.0 support for both your primary GPU slot and at least one M.2 slot. MSI’s implementation here provides two PCIe 5.0 M.2 slots, which matters if you’re running Samsung 990 PRO drives or planning to upgrade when PCIe 5.0 SSD prices drop.

The mandatory USB4 support on X870E boards is where things get interesting. MSI provides two USB4 Type-C ports on the rear I/O, each capable of 40Gbps throughput. I tested this with a Thunderbolt 4 dock and an external NVMe enclosure. The dock worked flawlessly with daisy-chained displays and USB peripherals. The NVMe enclosure hit 3.2GB/s read speeds, which is proper fast for external storage.

But here’s the thing about X870E versus B650E: you’re paying roughly £50-70 more for USB4 and guaranteed dual PCIe 5.0 M.2 slots. If you don’t need USB4 and one PCIe 5.0 M.2 slot is enough, B650E boards offer better value. The MSI MAG B650 TOMAHAWK WIFI costs significantly less and handles the same CPUs just fine.

MSI’s gone with Renesas RAA229131 PWM controller paired with sixteen 80A power stages for the CPU VCore. That’s 1280A of theoretical current delivery, though real-world Ryzen 9 9950X power draw tops out around 230W (roughly 190A at 1.2V) even when hammered with Prime95. The headroom here is massive.

I tested VRM thermals with a Ryzen 9 9950X running Cinebench R23 for 30-minute loops at stock settings, then with PBO enabled pushing 230W package power. Stock configuration saw VRM temperatures peak at 52°C. With PBO maxed out, the VRM heatsink reached 61°C. Both figures are excellent. The heatsink design uses a thick aluminium block with proper surface contact across all MOSFETs, and there’s actual airflow from the rear I/O area.

The 8+4 pin CPU power connector configuration is standard for high-end AM5 boards. You need both connectors populated if you’re running a 16-core chip with PBO enabled. I initially tested with just the 8-pin connected and the system refused to POST with PBO settings saved. Fair enough.

Memory power delivery uses a dedicated 2-phase circuit with 80A stages. This matters for DDR5-6400 and beyond, where DIMM voltage can climb to 1.4V or higher. I tested with G.Skill Trident Z5 RGB DDR5-6400 CL32 (two 32GB modules) and the board handled EXPO profiles without complaint. Manual tuning to DDR5-6800 CL34 worked but required 1.45V DRAM voltage, and the memory VRM stayed below 55°C throughout stability testing.

Right, let’s talk about MSI’s BIOS because this is where I get frustrated with them. Click BIOS 5 looks modern with its graphical interface and mouse support, but the menu organisation is proper messy. Finding specific settings requires remembering which of the seven main categories they’re buried under. Want to adjust CPU loadline calibration? That’s under OC settings, not CPU configuration. Memory subtimings? Hidden three levels deep in the DRAM configuration menu.

The EZ Mode is fine for basic users. It shows CPU temperature, fan speeds, boot priority, and EXPO profile selection. You can enable EXPO and adjust fan curves without touching Advanced Mode, which is genuinely useful for straightforward builds.

Fan control offers six headers total: one CPU fan, one CPU optional/AIO pump, and four system fan headers. Each header supports PWM or DC mode with customisable curves. But here’s the annoying bit: the curve editor only allows five points, and the temperature source options are limited. You can’t set chassis fan curves based on chipset temperature, which would be useful for the bottom fan header near the M.2 slots. ASUS boards have offered this for years.

Memory overclocking tools are comprehensive. MSI includes AMD’s EXPO profile support (obviously) plus manual timing adjustment for every primary, secondary, and tertiary timing. The Memory Try It feature provides pre-tested overclocking profiles from DDR5-4800 through DDR5-8000, though anything beyond DDR5-7200 is silicon lottery territory.

BIOS updates are straightforward using M-Flash, MSI’s built-in updater. I updated from version 1.00 to 1.20 (released December 2025 with improved Ryzen 9000 series support) without issues. The update took roughly four minutes, and the board auto-rebooted twice during the process. No dramas.

I tested with two configurations: 2x32GB G.Skill Trident Z5 RGB DDR5-6400 CL32 and 4x16GB Corsair Vengeance DDR5-6000 CL30. The G.Skill kit ran its EXPO profile without adjustment, hitting DDR5-6400 at 1.35V with 32-38-38-96 timings. AIDA64 memory bandwidth measured 92.4GB/s read, 85.1GB/s write, 88.3GB/s copy, and 78.2ns latency. Those numbers align with what Ryzen 9000 series CPUs typically achieve.

The Corsair 4x16GB configuration required manual tuning. EXPO initially failed to POST at DDR5-6000. Dropping to DDR5-5600 worked immediately, which is expected behaviour when populating all four slots on AM5. The memory controller has to drive more DIMMs, which limits achievable frequencies. I manually tuned to DDR5-5800 CL30 at 1.38V, which remained stable through 12 hours of TM5 memory testing.

For manual overclocking enthusiasts, this board offers proper flexibility. I pushed the 2x32GB kit to DDR5-6800 CL34 at 1.45V, which required manual subtiming adjustments (tRFC from 560 to 480, tRRD_L from 8 to 6, tFAW from 32 to 24). This configuration passed four hours of TM5 but occasionally threw WHEA errors under heavy workloads. DDR5-6600 CL32 at 1.42V proved more reliable for daily use.

Five M.2 slots is generous for an ATX board at this price point. Two slots support PCIe 5.0 x4 (M2_1 and M2_2), whilst the remaining three run PCIe 4.0 x4. All five slots support M.2 2280 drives, and M2_1 through M2_3 also accommodate 22110 length drives. Each slot includes a dedicated heatsink with thermal pads.

I tested M.2 thermals with a Samsung 990 PRO 2TB in the M2_1 slot (top position, PCIe 5.0). During a 100GB sequential write test, the drive’s controller temperature peaked at 67°C with the heatsink installed. Removing the heatsink saw temperatures climb to 82°C under the same workload. The heatsinks work, though they’re basic aluminium blocks rather than the fancy finned designs on flagship boards.

SATA connectivity is limited to four ports, down from six on many competing boards. This is a deliberate cost-cutting measure on newer chipsets. If you’re running multiple SATA SSDs or mechanical drives, you’ll need to plan accordingly. I’d have preferred six ports given the board’s positioning, but MSI clearly expects users to prioritise M.2 storage.

The USB4 ports are the headline feature here. Each port delivers 40Gbps bandwidth with support for USB Power Delivery (up to 27W), DisplayPort Alt Mode, and PCIe tunnelling. I tested with a CalDigit TS4 Thunderbolt 4 dock, which worked perfectly despite Thunderbolt technically being an Intel technology. The dock powered two 4K displays via DisplayPort, charged my laptop at 96W, and provided full-speed USB 3.2 connectivity to attached peripherals.

The 2.5GbE networking uses Realtek’s RTL8125BG controller, which is standard for boards in this price range. I tested sustained network transfers over a 2.5GbE switch and achieved 2.35Gbps (293MB/s) throughput, which is within expected performance. The controller doesn’t support multi-gig speeds beyond 2.5GbE, so if you need 5GbE or 10GbE, you’ll want a PCIe network card.

WiFi 6E via MediaTek MT7922 provides tri-band wireless with maximum theoretical speeds of 2400Mbps. Real-world testing with an ASUS RT-AXE7800 router positioned 5 metres away (one wall between) achieved 1.2Gbps download and 950Mbps upload on the 6GHz band. The 5GHz band managed 680Mbps down and 520Mbps up. Bluetooth 5.3 is included for wireless peripherals.

Internal USB headers include one USB 3.2 Gen 2 Type-C header (front panel), one USB 3.2 Gen 1 header (two ports), and two USB 2.0 headers (four ports total). That’s sufficient for most case configurations, though enthusiast cases with multiple front USB-C ports might need a hub.

Against the ASUS TUF GAMING X870E-PLUS WIFI, MSI’s board costs roughly £40 less whilst offering comparable VRM performance (actually higher amperage per phase) and identical PCIe 5.0 M.2 slot count. ASUS wins on WiFi (WiFi 7 versus WiFi 6E) and BIOS usability, but you’re paying extra for those improvements. If WiFi 7 doesn’t matter to you yet (and frankly, WiFi 7 routers are still expensive), the MSI board delivers better value.

The Gigabyte B650E AORUS ELITE X represents the budget alternative. It costs roughly £40-50 less than the MSI board but drops to B650E chipset (one PCIe 5.0 M.2 slot instead of two, no USB4), weaker VRM (14+2+1 phases with 60A stages), and no integrated WiFi. For Ryzen 5 or Ryzen 7 builds where USB4 isn’t needed, the Gigabyte board makes more sense. But if you’re building with a Ryzen 9 chip and want full platform features, the MSI board justifies its premium.

MSI’s own MAG X870 TOMAHAWK WIFI sits about £30 higher than the PRO X870E-P WIFI. The TOMAHAWK adds RGB lighting, slightly better audio (ALC4082 versus ALC4080), and a more robust VRM heatsink design. The core specifications are nearly identical otherwise. Unless you specifically want RGB integration or prefer the TOMAHAWK’s aesthetic, the PRO board offers better value.

Header labelling is clear with white text on black PCB. Even the tiny front panel headers (power switch, reset, LEDs) are marked legibly. The 24-pin ATX power connector sits in the standard mid-right position, and the 8+4 pin CPU power connectors are top-left where they should be.

M.2 installation requires removing the heatsinks, which attach via spring-loaded screws. The screws are captive, so you won’t lose them. Each heatsink includes a thermal pad already applied. I installed five M.2 drives during testing (mix of 2280 and 22110 lengths) and encountered no fitment issues.

The BIOS flashback button on the rear I/O is useful for updating firmware without a CPU installed. I didn’t need to use it (the board shipped with Ryzen 9000 support already enabled), but it’s there if you buy early stock with older firmware.

One minor annoyance: the Debug LED display is positioned near the 24-pin power connector rather than somewhere more visible. When troubleshooting POST issues, you’ll need to crane your neck or use a mirror to read the two-digit code. ASUS typically places these near the memory slots where they’re easier to see.

The X870E chipset commands a premium over B650E, and that premium needs justification. For this board, the value proposition depends entirely on whether you need USB4 and dual PCIe 5.0 M.2 slots. If you’re building with a Ryzen 9 processor, plan to use PCIe 5.0 storage, and have USB4 peripherals or docks, the extra cost makes sense. The VRM quality alone handles flagship CPUs without thermal concerns.

But if you’re building with a Ryzen 5 7600X or Ryzen 7 7700X, you’re overspending. A B650 board with decent VRM (10-12 phases) will handle those CPUs perfectly well, and you won’t use the additional PCIe 5.0 lanes or USB4 connectivity. Save £60-80 and put it toward a better GPU or more storage.

Against competing X870E boards, MSI’s pricing is competitive. The ASUS TUF GAMING X870E-PLUS WIFI costs more for WiFi 7 and better BIOS. The Gigabyte X870E AORUS ELITE costs similarly but offers weaker VRM. ASRock’s X870E boards tend to run cheaper but compromise on build quality and thermal solutions.
