Silver 1U rackmount server chassis with ten front 2.5″ drive bays

Supermicro

Supermicro SYS-111C-NR 1U barebone server, LGA-4677, C741, 16 DIMM DDR5, 10× 2.5″ bays, 860W redundant PSU

SKU CH-WY6B-BZTNN MPN SYS-111C-NR

1U barebone server with LGA-4677 socket, C741 chipset, 16 DDR5 DIMM slots and 10 hot-swap 2.5″ bays

  • 1U barebone fits dense racks with 111 mm height
  • 16 DDR5 DIMM slots reach 4800 MT/s
  • 10 front 2.5″ hot-swap bays accept SAS with controller
  • Redundant 860W Platinum PSU keeps system running
  • Dual PCIe 5.0 x16 slots plus dual AIOM for expansion

1U barebone for Xeon Scalable

The Supermicro SYS-111C-NR is a 1U server barebone built around the LGA-4677 socket and Intel C741 chipset. It supports a single 4th Gen Xeon Scalable processor with a thermal design power of up to 350W. Sixteen DIMM slots accept DDR5 memory running at up to 4800 MT/s. Redundant platinum-rated 860W power supplies are included.

Suits dense compute, not GPU farms

This platform suits workloads that need high memory capacity and fast front storage in a single rack unit. The ten hot-swap 2.5″ drive bays can be configured with optional NVMe support. Builders who require multiple double-width accelerators or more than two PCIe 5.0 x16 slots should evaluate larger chassis.

Sixteen DDR5 slots define memory ceiling

The maximum supported memory speed is 4800 MT/s across all sixteen slots, and the board accepts 3DS RDIMM modules. This DIMM count and speed combination sets the practical limit for in-memory datasets on this system.

Questions about this item

What maintenance or replacement will the redundant 860W power supplies need later?

The redundant 860W Platinum power supplies are hot-swappable, so a failed unit can be replaced without shutting down the server.

Which limit appears first under sustained load with a 350W TDP processor installed?

The 350W TDP ceiling of the LGA-4677 socket is the primary thermal limit; the 860W redundant PSUs provide headroom well above that figure.

How much noise and heat do the redundant 860W PSUs add when the system runs all day?

The Platinum-rated 860W redundant PSUs run at high efficiency, reducing waste heat and fan speed during continuous operation.
