Silver 2U rackmount server chassis with redundant power supplies

ASRock Rack

ASRock Rack 2U1G-B650/EVAC barebone server AM5 LGA 1718 EPYC 4005 4004 Ryzen 9000 8000 7000 DDR5 1200W

SKU CH-WKY2-6E2HW MPN 2U1G-B650/EVAC

2U rackmount barebone with 1200 W 80-PLUS Platinum redundant power, AM5 socket for EPYC 4005/4004 and Ryzen 9000/8000/7000 CPUs, four DDR5 ECC UDIMM slots, one full-height PCIe 5.0 x16 slot.

  • Redundant 1200W 80-PLUS Platinum power supply
  • Single AM5 socket supports EPYC 4005 and 4004 processors
  • Four DDR5 DIMM slots accept ECC or non-ECC UDIMM
  • One full-height PCIe 5.0 x16 slot plus one PCIe 4.0 x4 slot
  • Dual Intel i210 1GbE ports with two M.2 slots

2U barebone with 1200 W CRPS

This 2U rackmount barebone includes a redundant 1+1 CRPS power supply rated at 1200 W with 80-PLUS Platinum efficiency. The chassis provides one full-height dual-slot PCIe 5.0 x16 slot and one full-height half-length PCIe 4.0 x4 slot. Two 1 GbE RJ45 ports are driven by an Intel i210 controller.

Processor support scope

The single AM5 socket accepts AMD EPYC 4005 or 4004 processors and AMD Ryzen 9000, 8000 or 7000 series CPUs. Four DDR5 UDIMM slots support ECC and non-ECC memory in a 2DPC layout. Builders who need multi-socket configurations or registered DIMM support should look elsewhere.

Redundant power and PCIe 5.0 slot

The 1200 W 1+1 CRPS unit delivers Platinum-class redundancy for continuous operation. The single PCIe 5.0 x16 slot limits the system to one full-length accelerator or GPU; workloads requiring multiple double-width cards cannot be accommodated.

Highlights

  • Redundant 1200W 80-PLUS Platinum power supply
  • Single AM5 socket supports EPYC 4005 and 4004 processors
  • Four DDR5 DIMM slots accept ECC or non-ECC UDIMM
  • One full-height PCIe 5.0 x16 slot plus one PCIe 4.0 x4 slot
  • Dual Intel i210 1GbE ports with two M.2 slots

Questions about this item

How loud or hot does the 1200W 80-PLUS Platinum CRPS supply get when the server runs continuously?

The redundant 1200W CRPS units are 80-PLUS Platinum rated, so they run efficiently and generate less waste heat under sustained load.

Which processor and memory must I supply to complete this barebone?

You need an AMD EPYC 4005 or 4004, or a Ryzen 9000, 8000 or 7000 series CPU for the AM5 socket, plus DDR5 ECC or non-ECC UDIMMs for the four DIMM slots.

Will my existing PCIe 4.0 add-in cards work in the expansion slots?

Yes, the FHHL PCIe 4.0 x4 slot accepts PCIe 4.0 cards directly, and the FHFL PCIe 5.0 x16 slot is backward compatible with PCIe 4.0 devices.
