A low-cost alternative for Ryzen systems to the high-calibre but higher-cost motherboards is the B350 range. Today we are testing the ASRock AB350 Gaming K4 motherboard, coming in under the radar just below $100. It offers almost everything its bigger cousins provide except SLI, but single GPU users can find a home with a motherboard like this one. Our aim today is to ascertain whether the ASRock AB350 Gaming K4 can be a top value proposition with the B350 chipset in play.

With the ASRock AB350 Gaming K4, as the name seems to imply, ASRock wants it two ways: a competitive gaming motherboard in the B350 chipset space. No idea why it is called the 'AB350', that's just something ASRock seems to do, but the goal of the board here is to target the gaming crowd. That means having a relatively fully black PCB, a set of red aluminium heatsinks, and a full-length PCIe slot for graphics that has extra reinforcement to take the toughest pixel pushing PCIe powerhouses. The top full-length slot runs in PCIe x16 mode from the CPU, while the second slot also from the CPU, but is limited to PCIe x4, and shares bandwidth with one of the M.2 slots.
