Target Workload and CPU Platform

The RS300-E8-PS4 is a 1U rackmount barebone server built for general-purpose workloads. It accepts Intel Xeon E3-1200 v3 processors in an LGA 1150 socket with the Intel C224 chipset. The system targets buyers who need a compact, single-socket platform for standard compute tasks rather than high-density virtualisation or GPU-heavy acceleration.

Sustained Load Behaviour and Expansion

ASUS specifies that the platform operates at up to 40°C ambient stress, indicating stable performance under continuous load. Expansion includes one PCI Express 3.0 x16 slot running at x8 link, one PCI Express 3.0 x8 slot at x4 link, and a dedicated PIKE slot for storage add-in cards. Dual-channel DDR3 1600/1333 memory scales to 32 GB across four 240-pin slots with ECC support.

Thermals, Noise and Power Delivery

A single 400 W 80PLUS Gold power supply handles conversion efficiency for typical rack environments. The Aspeed AST2300 BMC with 32 MB video memory provides out-of-band management via ASWM Enterprise and ASMB7-iKVM without taxing the main CPU. Quad Intel I210-AT controllers deliver four 1 GbE ports for redundant network connectivity. Buyers needing redundant power supplies or higher-wattage configurations will need a different chassis.

Questions about this item

How loud does the single 400W 80PLUS Gold supply get when the server runs at 40°C all day?

The 400W 80PLUS Gold unit is rated for continuous operation at up to 40°C ambient, so fan speed stays moderate under sustained load.

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

You need an Intel Xeon E3-1200 v3 family CPU for the LGA 1150 socket and DDR3 1600/1333 ECC UDIMMs, up to 32 GB across four 240-pin slots.

Will my older SATA 3 Gb/s drives work with the onboard SATA ports?

Yes, the board provides two SATA 300 and four SATA 600 ports, so legacy 3 Gb/s drives connect without adapters.
