  • Near-silent operation at low loads through Zero RPM fan mode
  • Clean, stable power delivery using resonant LLC with DC-to-DC conversion
  • Reduced coil whine for quieter performance with advanced topology

Compact 1U ATX power supply

The KHACHIMO SP700-1R is a 1U form-factor ATX unit rated at 700W, designed for rackmount servers and slim workstations where vertical space is at a premium. It suits system integrators and IT teams who need standard ATX output in a single rack unit.

Compatibility checklist

Verify that your chassis accepts a 1U PSU and provides the required mounting points for this form factor. Confirm the motherboard uses a standard ATX 24-pin connector and that the cable lengths reach your board layout in a shallow case. Ensure the total system draw stays within the 700W rating.

Sustained-load behaviour

An 80 PLUS Gold rating means the unit maintains high efficiency across typical operating ranges, reducing waste heat during continuous operation. Resonant LLC topology with DC-to-DC conversion delivers stable voltage regulation under prolonged load while suppressing coil whine. The Zero RPM fan mode stays disengaged once thermal thresholds rise, so active cooling runs steadily during extended heavy workloads.
