Compact 1U ATX supply for rack builds

The KHACHIMO ST-250UP is a 1U form-factor ATX power supply rated at 250W. It targets system integrators and IT professionals assembling rack-mount servers or slim workstations where vertical space is limited. Buyers who need higher wattage for multi-GPU configurations or full-tower builds should look elsewhere.

Tested unit with standard thermal profile

Each unit is test working before shipment, confirming that the 250W output reaches specification under load. The 1U chassis uses an internal fan to move air through the narrow enclosure, producing audible airflow typical of rack-density power supplies. Power draw at the wall will reflect the 250W DC rating plus normal conversion losses.

No extra cables or software included

The package contains only the power supply itself; no modular cables, mounting rails or monitoring utilities are bundled. Installers must provide ATX leads and 1U rack screws suited to their chassis. First listed by the manufacturer in March 2024, the unit carries no additional firmware or management features.

Questions about this item

How do I mount the 1U 250W ATX unit in a standard rack and which orientation avoids blocking the exhaust?

Slide the 1U chassis into the rack rails, secure the front flange screws, and ensure the rear fan blows toward the hot aisle so heated air exits the cabinet.

Which component inside the 250W supply is most likely to need replacement after continuous operation?

The internal cooling fan is the primary wear item; its bearings degrade first under 24/7 load.

At what sustained load does the 250W ATX supply hit its thermal limit first?

Continuous output near the 250W rating causes internal temperatures to reach the protection threshold before any voltage rail drops out of spec.
