ATX board for AM4 Ryzen CPUs with dual M.2 slots, PCIe 4.0 support, WIFI 5 and 1 Gb Ethernet
Option PRIME B550-PLUS AC-HES
The ASUS PRIME B550-PLUS AC-HES is an ATX motherboard built for AMD Ryzen 3000, 4000G, 5000 and 5000G series processors. It delivers PCIe 4.0 graphics and storage support when paired with Ryzen 3000 or 5000 series CPUs. Integrated WIFI 5 and 1 Gb Ethernet provide network connectivity out of the box.
This board suits builders who need dual M.2 slots, six SATA ports, rear USB 3.2 Gen 2 Type-C and front-panel USB 3.2 Gen 1 Type-C headers. Users requiring more than 1 Gb Ethernet or additional PCIe 4.0 lanes from the chipset should consider other chipsets.
The top M.2 socket accepts 2242, 2260, 2280 and 22110 drives and runs at PCIe 4.0 x4 with Ryzen 3000 or 5000 series CPUs, dropping to PCIe 3.0 x4 with Ryzen 4000G or 5000G series. This single specification determines whether your SSD achieves its rated throughput.

같은 제품군에서 메모리·쿨러·클럭이 다릅니다 — 결정 전에 비교해 보세요.
Align the board's nine mounting holes with the case standoffs, fasten all screws, then connect the 24-pin ATX and 8-pin EPS power cables before adding any expansion cards.
Clean dust from the VRM heatsink, PCH heatsink, and fan headers every few months using compressed air; check that all fan cables stay seated in the hybrid headers so Fan Xpert 2 can regulate speeds.
The 8+1 DrMOS power stages and alloy chokes set the practical ceiling for CPU current delivery; if VRM temperatures rise, Fan Xpert 2 will spin the hybrid headers faster to protect the capacitors.
