SuperServer 2U barebone for Xeon LGA 4189
This Supermicro SuperServer SYS-520P-WTR is a 2U rackmount barebone built around the Intel C621A chipset and an LGA 4189 socket for Xeon processors. It ships without a CPU or memory installed, providing a chassis, motherboard and cooling foundation for custom integration. The platform targets organisations that assemble their own compute nodes from validated components.
Suits builders who need PCIe 4.0 expansion
The system offers two full-height full-length PCIe 4.0 x16 slots, one low-profile PCIe 4.0 x16 slot and a PCIe 3.0 x4 M-key slot for 2280 or 22110 modules. Dual Intel X550 controllers deliver two 10 Gigabit RJ45 ports plus a dedicated IPMI LAN interface. Buyers who require onboard GPU compute or single-thread frequency optimisation should evaluate alternative platforms.
Four 3.5-inch hot-swap bays accept NVMe
The front cage supports four 3.5-inch hybrid bays that each operate with NVMe or SATA 600 devices, backed by ten SATA ports and RAID 0, 1, 5 or 10 on the chipset. Maximum memory capacity reaches 2 TB with eight 256 GB DRAM DIMMs or 3 TB when four 512 GB persistent memory modules are combined with four 256 GB DRAM DIMMs. ECC is supported across all eight 288-pin slots.

Questions about this item
How much heat does the ASPEED AST2600 BMC generate when the SYS-520P-WTR idles in a closed rack all day?
The ASPEED AST2600 BMC is a low-power management controller; its heat output is negligible compared with the Xeon CPUs and drives you will install, so total thermal load depends on those components.
What CPU cooler mounting pattern does the SYS-520P-WTR require for the LGA 4189 socket?
The board uses the standard LGA 4189 square ILM, so any cooler rated for that socket — including Supermicro’s own 2U heatsinks — will mount without an adapter.
Can the four 3.5 NVMe hybrid bays on the SYS-520P-WTR accept my existing 3.5 SATA drives without a carrier change?
Yes, each hot-swap bay takes a 3.5 NVMe or SATA drive directly; the same carrier handles both interfaces, so your current 3.5 SATA drives slide in and work immediately.
