Silver 4U rackmount server chassis with front drive bays and redundant power supplies

ASRock Rack

ASRock Rack 4U4G-WRX80/2T barebone server, sWRX8, 4 GPU

SKU CH-2CTZ-8DYZG MPN 4U4G-WRX80/2T

4U rackmount barebone with 1600 W platinum power supply, single sWRX8 socket for Threadripper PRO processors, eight memory slots.

  • 1+1 80-PLUS Platinum 1600W CRPS ensures redundant power
  • Single sWRX8 socket supports AMD Ryzen Threadripper PRO 5000WX/3000WX processors
  • 8 DIMM slots accept ECC and non-ECC memory modules
  • 4 FHFL dual-slot PCIe 4.0 x16 or 7 single-slot cards
  • 2 hot-swap 2.5" SATA bays plus 2 M.2 slots
  • Dual 10GbE RJ45 via Intel X710-AT2 with IPMI remote management

4U Rackmount Barebone for Four Dual-Slot GPUs

This 4U server barebone fits a single AMD Ryzen Threadripper PRO processor in the sWRX8 LGA 4094 socket. It delivers 1600 W of 80-PLUS Platinum redundant power and four full-height full-length dual-slot PCIe 4.0 x16 slots. Eight DIMM channels and two hot-swap 2.5" SATA bays complete the platform.

Suited for Compute-Dense GPU Workloads

The chassis targets users who need four double-width accelerators in a standard rack depth with IPMI remote management. Two onboard 10GbE ports by Intel X710-AT2 handle high-throughput networking. Builders requiring more than two internal SATA drives, more than eight memory modules, or single-slot GPU density beyond seven cards should evaluate other form factors.

Four Dual-Slot PCIe 4.0 x16 Slots Decide Fit

The backplane allocates either four dual-slot or seven single-slot PCIe 4.0 x16 lanes directly from the CPU. That fixed lane budget determines whether your accelerator count and width match the system. Verify your GPU quantity and slot width against this limit before purchase.

Questions about this item

Should I choose the four dual-slot or seven single-slot GPU configuration?

The chassis fits 4 FHFL dual-slot PCIe 4.0 x16 cards or 7 FHFL single-slot PCIe 4.0 x16 cards; pick dual-slot for maximum per-GPU bandwidth, single-slot for higher card count.

What does the 1600 W 80-PLUS Platinum rating deliver in a live rack?

The 1+1 redundant CRPS units supply up to 1600 W at 80-PLUS Platinum efficiency, powering the CPU, memory, drives and up to four dual-slot GPUs simultaneously.

How does the PCIe 4.0 x16 interface cap GPU throughput?

Each full-height slot runs at PCIe 4.0 x16, so GPU data moves at the full lane width the platform provides without down-negotiation.
