Supermicro

Supermicro SYS-511E-WR barebone server, LGA-4677, 4th Gen Xeon, 300W TDP

SKU CH-GXK5-9Y8QH MPN SYS-511E-WR

1U barebone server for single 4th Gen Xeon up to 300W TDP with eight DDR5 slots, two PCIe 5.0 x16 slots and dual 1G LAN

  • Single Socket E (LGA-4677) for 4th Gen Xeon processors
  • Supports up to 300W TDP for demanding workloads
  • 8 DIMM slots for DDR5 memory up to 4800 MT/s
  • Two PCIe 5.0 x16 full-height slots for GPU or add-in cards
  • Intel i210 1G LAN plus dedicated IPMI LAN for management

Purpose-built 1U server barebone

The Supermicro SYS-511E-WR is a 1U barebone server designed for single-socket Intel Xeon Scalable processors in the LGA-4677 package. It targets virtualization, cloud computing and value IaaS deployments where dense compute is required. The platform supports CPUs up to 300W TDP and uses the Intel C741 chipset. It suits integrators building entry GPU servers or data-centre nodes.

Expansion slots and onboard I/O

Two full-height full-length PCIe 5.0 x16 slots provide high-bandwidth links for GPUs or accelerators. A low-profile PCIe 5.0 x8 slot wired in an x16 connector adds flexibility for networking or storage cards. An M.2 slot carries a PCIe 3.0 x2 NVMe interface for fast boot or cache drives. Dual onboard 1G LAN ports and a dedicated IPMI LAN handle management and data traffic.

Tool-less chassis and thermal limits

The 1U chassis uses tool-less drive trays and slide rails to speed rack installation and service. Eight DDR5 RDIMM slots support 3DS modules at 4800 MT/s, but memory population rules for high-capacity DIMMs can limit maximum reachable capacity. Cooling is rated for the 300W TDP ceiling; processors above that limit are not supported. Builders needing more than three add-in cards or higher CPU power must choose a different platform.

Questions about this item

Which memory modules will need replacing if I upgrade beyond 4800 MT/s DDR5?

The board has eight DIMM slots for 3DS DDR5 RDIMM running at up to 4800 MT/s; faster modules would require a platform change.

What thermal limit appears first when the 300W TDP Xeon runs continuously?

The single LGA-4677 socket is rated for up to 300W TDP, so the processor's own thermal ceiling is the first constraint under sustained load.

How loud do the fans get when both PCIe 5.0 x16 slots are fully loaded all day?

The 1U barebone uses high-speed system fans to cool a 300W TDP CPU and dual full-height PCIe 5.0 x16 cards, producing noticeable airflow noise in a rack.
