Is the motherboard in your Ryzen PC broken, or are you building a compact PC using a processor you already own? The Asus Prime B350M-A is a reliable Micro-ATX motherboard for AMD Ryzen on the AM4 socket. It fits into smaller cases and also supports the first Ryzen 1000 processors. This makes it a cost-effective replacement for a faulty motherboard in an older Ryzen PC.

Why this motherboard?

From Ryzen 1000 to 5000. The motherboard has the latest BIOS, so even a Ryzen 5000 will work straight away.
Compact. Micro-ATX fits into most cases, including smaller models.
Fast storage. 1 M.2 slot (PCIe 3.0 x4 or SATA) for an NVMe SSD, plus 6 SATA ports.
Up to 64GB of memory. 4 DDR4 slots.
3 video outputs. HDMI, DVI-D and VGA, for a Ryzen processor with integrated graphics. Handy if you still have an older monitor.

Will my processor work?

Yes, as long as it’s a Ryzen for the AM4 socket. The motherboard features the latest BIOS from Asus and therefore works straight away with Ryzen 1000, 2000, 3000 and 5000 series processors. You don’t need to update anything yourself.

Asus Prime B350M-A or ASRock B450 Pro4?

The Asus is compact and good value, and the best choice for repairing an older Ryzen PC. If you want more connectivity options for a new PC, go for the ASRock B450 Pro4 R2.0: larger ATX form factor, 2 M.2 slots, USB-C and more expansion slots.
