The Snow Queen

ASRock B550 Steel Legend is one of the most balanced mid-price motherboards for AM4 processor socket. Made in white and decorated with built-in ARGB-backlight, which is synchronized with other PC components through the ASRock Polychrome application. She has an analogue in dark colours — ASRock B550 Extreme4.

cold metal

The processor power circuit consists of 14 phases (10 directly to the processor cores and 4 more to additional chip components). All mosfets, without exception, are covered with an aluminium radiator. Also, both M.2 disk slots are equipped with heatsinks, and the bottom one is combined with the chipset heatsink.

high speed interface

The top PCI-E x16 graphics card slot is metal-reinforced to support the weight of even a flagship graphics card and runs on the fast PCI-E 4.0 bus. The same applies to the upper M.2 (up to 64 Gbps). The lower M.2 is limited to only two PCI-E 3.0 lanes (up to 16 Gbps). But installing a second M.2 SSD does not disable half of the SATA3 connectors.

One piece construction

The rear interface panel plug is attached directly to the decorative casing — this is a panacea for both forgetfulness when assembling a PC and dust already during operation. The ASRock B550 Steel Legend audio path combines the top-end Realtek ALC1220 audio codec and Texas Instruments headphone amplifier. The network is represented by 2.5-gigabit Ethernet and an M.2 Key-E slot for Wi-Fi.
