Workstation board for Xeon W-3400 and W-2400
The ASUS Pro WS W790-ACE is a CEB workstation motherboard built around the Intel W790 chipset and LGA 4677 socket. It targets professionals who need reliable 24/7 operation with up to 2TB of ECC DDR5 memory across eight 288-pin slots running in quad-channel mode.
Sustained load with 12+1+1 power stages
A 12+1+1 power-stage design feeds the CPU through an 8-pin PCIe connector while massive VRM, chipset and M.2 heatsinks dissipate heat during long render or compute sessions. Five PCIe 5.0 x16 slots maintain x16, x16, x16, x0/x8 or x16/x8 bandwidth configurations so multiple GPUs or accelerators keep full throughput without throttling.
Straightforward install if the case fits CEB
The board follows the CEB form factor so a compatible chassis is required; standard ATX holes will not align. Front and rear USB 3.2 Gen 2x2 Type-C headers are clearly labelled, and the two M.2 slots (2242/2260/2280/22110 and 2280) use tool-free latches. SlimSAS cables for the three SlimSAS ports are not included and must be sourced separately.

Questions sur cet article
Does this board fit a standard E-ATX case?
The Pro WS W790-ACE uses the CEB form factor, which is wider than E-ATX. Check your chassis specifications for CEB support before purchasing.
Can I run four DDR5 RDIMMs at the rated 6800 MT/s?
The board supports DDR5 6800 (OC) via Intel XMP 3.0. Achieving that speed depends on the specific memory kit and the Xeon processor installed.
How many PCIe 5.0 x16 slots are wired for full x16 bandwidth?
Three slots run at x16 simultaneously; the fourth and fifth share lanes in x0/x8 or x16/x8 configurations depending on the CPU.
