Power delivery for high-end CPUs

This MAXSUN motherboard accessory is built for builders who want a robust 12+2+1 phase DrMOS design rated at 50A per stage. Dual EPS 8-pin connectors feed up to 300W to the socket, giving Ryzen 9 9950X3D and similar high-end processors the stable current they demand under heavy loads.

PCIe 5.0 M.2 capacity

The board provides two PCIe 5.0 x4 M.2 slots plus one PCIe 4.0 x2 slot, so storage throughput scales with the latest drives. Four DDR5 DIMM slots accept up to 192GB of memory and support overclocked speeds beyond 8000MHz, while a single PCIe 5.0 x16 slot handles modern graphics cards directly from the CPU.

Thermals and power in normal use

Premium 8-layer PCB construction and heatsinks on the VRM and M.2 areas keep temperatures controlled during sustained workloads. Integrated MediaTek MT7922 Wi-Fi 6E, Bluetooth 5.2 and Realtek 2.5GbE LAN add minimal power draw, and fan headers let the system tune airflow for quiet operation.
