1U 350W ATX Power Supply for Compact Servers

The KHACHIMO IDC SO-350U is a 1U form-factor ATX power supply rated at 350W, designed for rackmount servers and space-constrained workstations. It delivers reliable power density for systems where vertical clearance is at a premium.

Verify 1U Clearance and ATX Connector Compatibility

Confirm your chassis accepts a 1U high unit and that your motherboard uses standard ATX power connectors. The unit’s switching topology requires adequate airflow through the rack enclosure for stable operation.

80 PLUS Gold Efficiency with Zero RPM Fan Mode

Certified 80 PLUS Gold efficiency reduces waste heat and operating costs while supporting modern standby sleep states. The Zero RPM fan mode stops the fan at low and medium loads, and resonant LLC topology with DC-to-DC conversion minimises coil whine for quieter racks.

Questions about this item

What cables or accessories come with the KHACHIMO SO-350U and what must I buy separately?

The unit itself is supplied; no cables, mounting hardware or adapters are listed in the specifications, so assume only the power supply is included.

Should I choose this 350 W model or look for a higher-wattage version?

At 350 W this supply suits compact systems with modest CPU and GPU power draw; select a higher-output model only if your build exceeds that budget.

What does the 80 PLUS Gold rating mean for daily operation of this 350 W unit?

It certifies high efficiency across the load range, so the PSU wastes less power as heat, runs cooler and keeps the Zero RPM fan off longer during light workloads.
