Very good Motherboard works well and fits my pc perfectly

Amazing Motherboard

https://www.asus.com

Great budget mb. Runs flawlessly with 32gm ran and rtx3060 gpu

Very pleased

Good purchase would recommend for anyone looking to upgrade their setup

asus b550m a ac for the win

I have enjoyed this computer. for quite some time now. I haven't had any problems with it. It runs all my games and other Programs very well.

Not a bad deal.

easy setup I have had no issues with this board. Ryzen 5 3600 CPU and AMD Radeon RX 580 GPU with Deep Cool AK400 digital cooler, all installed with ease. Wifi and bluetooth both work excellent on this.

Bargain

Great board with ample features for the money.  IO is good and the ASUS BIOS as always is ez to navigate and use.  Made for a nice office PC paired with a 5600G.

A great board for the price

Excellent product would recommend for a friend……..

Great product

This is a great motherboard if your are building your first pc. It has all the features you need while being mini atx. Overall I just wish there were more ARGB headers but this is a solid board.

Great board!

io shield back plate is a cheap piece of bare metal, it could not fit because of the way the edges are folded

bare minimum excellence

Chantae

I really thought this bard was going to be able to OC with my ryzen 7 5800XT, I found that i can, but it was a struggle bus some. There was an excellent way that it installed, it just did it. I liked that. Armoury crate should have a monitoring tool overlay too

I was underwhelmed

Why do you make it so difficult to update the bios? It's impossible. This cap file cannot be opened. With Dell, you can have your system detected and have your bios and drivers updated automatically at a single website.

Difficult equipment

asus prime b550m-a ac micro atx motherboard, socket am4, amd b550 chipset front-facing micro ATX PCB with central AM4 CPU socket, four DDR4 DIMM slots to the right, dual PCIe expansion slots, SATA ports at lower right, silver VRM and chipset heatsinks, onboard 802.11ac antenna connectors and rear I/O including USB and HDMI; often used as a compact ATX-compatible build board for DIY PC systems.
