  • 80 PLUS Gold certification delivers high efficiency, lower consumption and cooler running
  • Zero RPM fan mode stops the fan at low and medium loads for silent operation
  • Resonant LLC topology with DC-to-DC conversion gives clean power and reduces coil whine

Compact 1U Server Power Unit

The KHACHIMO FSP400-701US is a 400W ATX power supply built to the 1U form factor for rack-mount servers and slim workstations. It suits system integrators who need efficient, reliable power in a shallow chassis where standard PSUs will not fit.

Installation Notes

The unit mounts with standard 1U screw spacing and uses a conventional ATX connector set, so no adapter cables are required. Zero RPM fan mode means the fan stays off at low and medium loads, reducing dust intake; ensure the chassis airflow path is unobstructed or the fan may spin up sooner than expected.

Pre-Order Checklist

Verify the case or rack shelf accepts a 1U-height supply and provides the correct mounting holes. Confirm the motherboard uses a standard 24-pin ATX main connector and the CPU power header matches the supplied cables. Ensure the total system draw stays within the 400W rating.

Perguntas sobre este artigo

How can I confirm the power supply is operating correctly after installation?

The unit is 80 PLUS Gold certified, so it should deliver high efficiency and run cooler under load. At low and medium loads the Zero RPM Fan Mode keeps the fan off for near-silent operation, and Modern Standby compatibility means the system should wake from sleep extremely quickly.

What comes in the box and what must I purchase separately?

The package contains the FSP400-701US 1U 400W ATX power supply unit itself. Standard ATX power cables for motherboard, CPU, GPU and drives are typically included, but any specialised connectors or mounting brackets for non-standard cases would need to be sourced separately.

Which version or capacity of this model should I choose?

This specific model is the FSP400-701US rated at 400W with 80 PLUS Gold efficiency. If your build requires more headroom for high-end graphics cards or heavy overclocking, you would need to look at a higher-wattage unit from a different product line.
