BIOS configuration is incredibly easy and not at all hard to understand. This motherboard also has access to β€œEZ Debug LEDs” which are great for diagnosing problems during boot. This is probably the best value AM4 motherboard at the moment, and it looks great in all-black builds. I would definitely recommend this motherboard ### ⭐⭐⭐⭐⭐ Best Value B550 Motherboard *by on Reviewed in the United Kingdom 24 April 2021* I wanted a good looking motherboard for my Black and White themed build. I didn't want an X570 as I would have to deal with annoying chipset fans. I then came across this motherboard. It had all the features I wanted. 6 system fan headers, POST Debug LED's, PCIe Gen 4 (only on the the first M.2 and PCIe x16 slots), M.2 heat sink with a Thermal Pad. The VRM's are solid and are easily handling with my Ryzen 7 5800X. Didn't need to update the BIOS using BIOS Flashback as it is April 2021 and all AMD 500 series Motherboards should have the new BIOS update if it was manufactured before the Zen 3 launch (November 2020). I am using a PCIe 4.0 M.2 NVMe SSD and a crystal disk mark run shows that I am getting Gen 4 speeds, even with a PCIe 3.0 GPU. I haven't touched any slot configuration settings. The BIOS also allows you to use voltage control on 3 pin fans. This was really god as the fans that came with my case are only 3 pin (Be Quiet Pure Base 500DX). The only "problem" I had with this board was that the grounding tabs on I/O shield weren't properly bent, so they went inside of the USB 3.1 and Ethernet ports. I tried to bend them back but ended up cutting my finger so I took unscrewed the Motherboard and moved it across slightly just enough so I could take out the I/O shield and bend it back properly. I accidentally broke one of the legs on the tab for the USB 3.1 port but the other one was still intact. This problem wasn't a huge deal but I recommend that you make sure that all the tabs on your I/O shield are bent properly. It wasn't necessary to bend it back but I did it anyway.Overall this is an excellent AMD B550 Motherboard with loads of features. Only cost me Β£130!!! ### ⭐⭐⭐⭐⭐ Great motherboard, no issues at all *by on Reviewed in the United Kingdom 8 January 2026* Amazing motherboard and works perfectly with no issues. Setup was straightforward and everything worked out of the box.Build quality feels solid, BIOS is easy to use, and it’s been stable with no crashes or problems so far. Great option for a Ryzen build and definitely worth the money. ## Frequently Bought Together - MSI B550-A PRO Motherboard ATX - Supports AMD Ryzen 3rd Gen Processors, AM4, DDR4 Boost (4400MHz/OC), 1 x PCIe 4.0/3.0 x16, 1 x PCIe 3.0/3.0 x16, 1 x M.2 Gen4 x4, 1 x M.2 Gen3 x4, HDMI, Gigabit LAN - AMD Ryzensets 5 5600X Processor (6 Cores/12Threads, 65W TDP, AM4 Socket, 35MB Cache, up to 4.6 GHz Max Boost, Wraith Stealth Cooler) - Corsair VENGEANCE LPX DDR4 RAM 32GB (2x16GB) 3200MHz CL16 Intel XMP 2.0 Computer Memory - Black (CMK32GX4M2E3200C16) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/212706243-msi-b550-a-pro-motherboard-atx-ryzen-3rd-gen-am4](https://www.desertcart.gr/products/212706243-msi-b550-a-pro-motherboard-atx-ryzen-3rd-gen-am4) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-17*
