With Ryzen and AM4 just around the corner, information on SFF-orientated AM4 motherboards has been scant. With only ATX leaked or shown so far, we were afraid that we’d see a LFF (large form factor) launch. Fear not though, with not one, but two boards from ASRock, the AB350M Pro4 and the AB320M Pro4.

The AB350M Pro4 appears to be a mid-range board, featuring AMD’s A350 chipset (go figure). From the information we have, the board has four DDR4 RAM slots, supporting speeds up to 2667MHz, two PCIex16 slots (x16 and not x16, the placard was incorrect), a single PCIex1 slot, a SATA M.2 slot, a PCIe x4 M.2 slot, and 4 SATA ports.
The AB variant supports overclocking.

The rear IO is relatively sparse, but includes a single USB Type-C connector. The board has moderately sized VRM heatsinks, which is a bonus!

Specs! ASRock has advised that this chart is incorrect in regards to slot specs, so take this with a grain of salt.

The same board, but in a more conventional rotation!

The lower specc’d A320M Pro4. The board features what appears to be an identical layout to the AB350M Pro4 above.

Identical rear I/O too.

And the spec list. Same goes for this, the PCIe lane info is not correct.

I’m excited, but we do need to see more AM4 SFF!
