  • Four SATA connectors support multiple storage drives in 1U chassis

Compact 1U server power supply

This 400W 1U ATX switching power supply fits server and industrial chassis where rack height is limited. It delivers up to 400W output for desktop or server workloads. The unit targets builders who need a slim form-factor PSU for advertising machines or similar embedded systems.

Non-modular cable set with active PFC

Active PFC corrects the power factor across a 100-264V input range. The fixed harness provides four SATA connectors, three D-type connectors, one 20+4Pin motherboard connector and one 4+4Pin CPU connector. Dual 4cm fans with temperature control manage airflow inside the 1U enclosure.

Replaces bulkier ATX units in 1U racks

The supply upgrades from standard-height PSUs that cannot fit a 1U slot while still covering 251-300W rated loads. The jump is worth it when rack density demands the 1U SSI Ver2.3 profile and the connector mix matches the board. Buyers who need modular cabling or higher rated wattage should look elsewhere.
