The ASRock B550 Phantom Gaming 4 is a full-size ATX board for AMD's AM4 socket, built on the B550 chipset. It covers the essentials for a mid-range Ryzen build: four DDR4 slots rated up to 4733 MHz, two M.2 slots, PCIe 4.0 on the main graphics and storage lanes, and four fan headers. It skips Wi-Fi, Bluetooth and USB-C, so it suits builders who use wired networking and a separate Wi-Fi card. Against pricier B550 boards it gives up premium audio, POST diagnostics and beefy VRM cooling, but it handles Ryzen 5 and Ryzen 7 chips without trouble.

Owners rate it highly as a no-frills B550 board that boots reliably and handles mainstream Ryzen chips. Complaints center on the missing wireless and USB-C features and on VRM heat with top-tier processors.
