Does its job. 7/28/2020 12:30:57 PM

Overall Review: Let's be honest; you're buying this mobo because it's one of the most inexpensive B550 ATX boards and you'd rather not scrounge for an X470/B450 and get a loaner CPU. For that purpose alone, this hits the nail on the head. Really isn't equipped with bells and whistles but it's not shooting to anyway. Decent board.

Great price, solid motherboard. The review is for ASRock review rebate program 7/22/2020 1:40:14 PM

Pros: Rebate aside, the motherboard looks and feels like a decent build. Put it together with Ryzen 5 3600 and Sapphire Radeon 5600XT. Works as expected, no issues so far, and expected speeds. Enough expandability, especially for the price paid. I like having two M2 slots and usb type C

Cons: Could probably stand to have a larger heat sink. not that it runs hot, but just in case.

Overall Review: I would recommend this motherboard. Quality build, has most of what you need at this price range.
