ASRock B550 Phantom Gaming-ITX/AX Review

Rating: 8.0.

B550 and mini-ITX can go hand-in-hand for AM4 buyers, so does the ASRock B550 Phantom Gaming-ITX/AX provide the necessary feature set and performance to make it a desirable option? The 8-phase power delivery solution, 8-layer PCB, and ample high-speed connectivity paint a positive picture, but let’s take a closer look.

Core to the ASRock B550 Phantom Gaming-ITX/AX is its passively cooled power delivery system. Built around an eight-phase solution, ASRock deploys six 90A DrMOS power stages for the CPU VCore portion specifically.

Added to the package are dual M.2 connectors, one of which runs with Gen 4 lanes and a cooling heatspreader. You also get 2.5 GbE from an Intel adapter and 802.11ax WiFi connectivity.

ASRock clearly ticks the main boxes with the B550 Phantom Gaming-ITX/AX, so let’s take a closer look at the motherboard itself.
