Good no-frills AM4 board
This is a decent budget board without fancy features, although I am disappointed that it doesn't have 2.5gbe, totally missed that in the product info.It's got plenty of fan headers, nice thick heatsinks on the VRMs and chipset.I am coming from an MSI Z490 so I'm already familiar with the BIOS, it's very easy to navigate.I used the flashback feature to update the BIOS without a CPU installed and it worked perfectly. I'm using a 5900xt on it and it's been good so far. It's got basic standard PBO feature for tweaking performance.

De las mejores placas madre en AM4
La MSI B550-A PRO V1 me ha salido excelente desde el primer día. La compré para un equipo con procesador AMD Ryzen y la instalación fue bastante sencilla, sin encontrar problemas durante el montaje o la configuración inicial. La calidad de construcción se siente muy buena y la placa se ve bastante sólida, especialmente por sus disipadores y el diseño general.En el uso diario ha funcionado de manera muy estable. He utilizado diferentes dispositivos y componentes sin experimentar problemas de compatibilidad, y las temperaturas se han mantenido bien. También me gusta bastante la cantidad de conex

MSI B550-A PRO V1 ProSeries
I battled this motherboard for the better part of three days before deciding that what I got is a lemon and that it's going back. On booting, instead of the normal logo splash screen, or what I assume is supposed to be a logo, I see a weird glitched screen that looks like a corrupt graphic file. That should've been a red flag and I should've stopped and sent the board back at that point. I would've saved myself a lot of time.Sometimes the board simply wouldn't turn on. Other times it would turn on but only if I held down the power for a few seconds. It needed me to add the memory sticks one at
