W790 WS, Intel® W790 Chipset, LGA 4677, 2 x Thunderbolt™ 4, E-ATX Motherboard

The advanced cooling system of the composite VRM heatsink provides efficient heat dissipation, which means users can enjoy high-performance computing without having to worry about thermal issues. The triple EBR cooling fans, XXL aluminum-alloy heatsink, aluminum fin array, and heat pipe work together to maintain optimal temperature levels for the system, ensuring smooth and stable operation even under heavy workloads.
The server grade PCB prevents PCB bending and improves signal integrity, giving higher PCIe 5.0 and memory performance as well as system stability, giving a reliable and long-lasting system without any compromise.
Unlike traditional motherboards that use analog power, this motherboard uses a next generation digital PWM (Pulse-Width Modulation) design, which provides CPU Vcore voltage more efficiently and smoothly, so that the stability and lifespan of the motherboard is greatly enhanced.
