Compact 1U rackmount server chassis

The Supermicro CSE-512L-200B is a 1U rackmount server chassis that fits a maximum 12" x 9.6" ATX motherboard and supports a single Intel or AMD processor. It ships with a 200W multi-output power supply and a 10cm PWM blower fan rated at 3,800 RPM. The 14" depth makes it suitable for shorter rack cabinets.

Two fixed 3.5″ drive bays and one expansion slot

The chassis provides two internal 3.5" drive bays fixed in place, with the manufacturer recommending SAS or enterprise SATA hard drives only. A single full-height half-length expansion slot is available but requires a separate riser card to install an add-in card. Front-panel controls include power and reset buttons plus five status LEDs.

Verify motherboard size

Confirm your motherboard does not exceed the 12" x 9.6" ATX maximum, as larger boards will not fit the 1U form factor. Ensure you have SAS or enterprise SATA hard drives, since consumer SATA drives are not recommended for this chassis. Check that a compatible riser card is sourced if you plan to use the expansion slot.

Questions about this item

When will the 10 cm 3800 RPM PWM blower fan need replacement?

The 10 cm 3800 RPM PWM blower fan is the only active cooling component; plan to replace it when bearing noise increases or airflow drops below what the chassis requires.

Which limit appears first during sustained loads — the 35 °C operating temperature ceiling or the 200 W power supply capacity?

The 200 W multi-output supply will reach its rated output before the 35 °C ambient limit becomes the constraining factor.

How loud and hot does the chassis get when the 10 cm blower runs continuously at 3800 RPM?

The single 10 cm 3800 RPM PWM blower moves enough air for the 200 W supply and two 3.5″ drives, but sustained operation at full speed produces noticeable airflow noise and exhaust heat within the 5 °C–35 °C operating range.
