Expanding Your Rig With the ASUS PRO WS W790-ACE Intel W790 LGA 4677 DDR5 SSI CEB Workstation Motherboard

High-end rendering and machine learning setups demand vast graphics and accelerator bandwidth. This board features five full-length PCIe 5.0 x16 slots. Because PCIe 5.0 doubles the bandwidth of previous generations, multiple GPUs or high-speed capture cards run without bottlenecks. In practice, this setup allows smooth multi-GPU scaling for rendering farms and deep learning development rigs.

Robust Memory Architecture for Intensive Datasets

Large-scale computational tasks consume massive amounts of system memory. This motherboard offers eight DDR5 DIMM slots arranged in a quad-channel layout. It supports up to 2 TB of ECC memory with speeds reaching up to 6800 MHz. Error-Correcting Code memory prevents silent data corruption during days-long renders. As a result, your critical data remains secure and stable throughout uninterrupted rendering sessions.

High-Speed Local Storage and RAID Protection

Fast access to large assets is vital for professional media production and data analysis. The board provides two onboard M.2 slots alongside four SATA III ports. You can configure hardware storage arrays using integrated RAID 0, 1, 5, and 10 modes. Therefore, you can configure fast scratch disks or redundant data pools directly on the motherboard.

Enterprise Networking and Peripheral I/O

Modern studios move vast project archives across local area networks daily. Dual onboard Ethernet ports deliver 10 Gigabit and 2.5 Gigabit connectivity. Consequently, network transfers finish rapidly without requiring supplementary add-in cards. For external devices, the rear panel provides USB 3.2 Gen 2×2 Type-C alongside multiple USB 3.2 Gen 2 ports.

Critical Build Verification

  • Confirm your PC chassis supports the SSI CEB form factor (305 mm x 277 mm).
  • Confirm your CPU is an Intel Xeon W-3400 or W-2400 series processor.
  • Confirm your power supply includes dedicated 8-pin EPS and 24-pin ATX connections.
  • Confirm your operating system environment runs 64-bit Windows 10 or Windows 11.
