Does it support Ryzen 5000 out of the box?

Newer stock ships with a BIOS that supports Ryzen 5000. Older boards may need a BIOS update first, which requires a compatible older CPU.

Is the VRM good enough for a Ryzen 9?

It works, but the VRM is basic and heats up under sustained all-core loads. A Ryzen 5 or Ryzen 7 is a better match.

How many M.2 drives can I install?

Two. The top slot is PCIe 4.0 with a heatsink; the lower slot is PCIe 3.0 and bare.

No. There is no wireless card, so you need an Ethernet cable or a separate Wi-Fi adapter.

What memory does it take?

Four DDR4 DIMM slots, up to 128GB, with overclocking support through the BIOS.

Is it ATX or micro-ATX?

It is full ATX, so it needs an ATX or larger case.

Our take on the ASRock B550 Phantom Gaming 4 AM4 AMD B550 SATA 6Gb/s ATX AMD Motherboard

The ASRock B550 Phantom Gaming 4 is a full-size ATX motherboard for AMD's AM4 socket, built on the B550 chipset. It runs Ryzen 3000, 4000G and 5000 series CPUs and gives you PCIe 4.0 to the graphics card and one M.2 slot, which the older B450 boards do not. It is a budget-minded board: the VRM is modest, there is no Wi-Fi and no USB-C header, and the second M.2 slot runs at PCIe 3.0. It suits builders who want a plain black ATX board with PCIe 4.0 and will not push a high-core CPU hard.

PCIe 4.0PraisedBuyers value the PCIe 4.0 graphics slot and first M.2 slot at this tier.
ConnectivityCriticisedNo Wi-Fi, no Bluetooth and no USB-C front-panel header, so add-ons cost extra.
