Retailing for around £100, the ASRock Fatal1ty AB350 Gaming K4 is targeting budget gamers who do not require multi-GPU capability. In doing so, ASRock offers up several tempting features, such as dual M.2 ports, RGB LED capability, and a 6+3-phase power delivery solution.

Aggressively targeting a £100 price point, ASRock's Fatal1ty AB350 Gaming K4 has managed to retain an impressive number of features associated with higher-end models. You get two M.2 slots, the second of which is intended for SATA devices but supports reduced speed PCIe operation, onboard red LED lighting, and USB Type-C (albeit at 3.0 5Gbps bandwidth).

A steel-reinforced PCIe slot sits alongside six SATA 6Gbps ports and four DIMM slots, so ample hardware expansion should be covered. How will the ASRock Fatal1ty AB350 Gaming K4 perform in our testing? Can it handle the strenuous demands of AMD's more power-hungry multi-core Ryzen processors?
