  • TypeATX
  • Fast wake-from-sleep and better low-load efficiency with Modern Standby compatibility
  • High efficiency operation lowering power consumption, noise and temperatures via 80 PLUS Gold certification
  • Near-silent operation at low and medium loads as the fan stops completely in Zero RPM mode

FSP 4U 500W Replacement Unit

This KHACHIMO power supply is built to replace the FSP500-60WSA-5K in 4U server or workstation chassis. It delivers 500 W of continuous power through a standard ATX form factor. The unit is new and carries 80 PLUS Gold certification for high efficiency across typical loads.

Suited for Modern Standby systems.

The Modern Standby compatibility and Zero RPM fan mode suit systems that prioritise fast wake times and quiet low-load operation. Builds requiring more than 500 W or non-ATX form factors should look at other units.

80 PLUS Gold efficiency at 500 W

The Gold-rated efficiency curve reduces power draw, heat output and fan noise under normal workloads. Resonant LLC topology with DC-to-DC conversion further tightens voltage regulation and limits coil whine.

Questions about this item

What form factor does the 500W FSP500-60WSA-5K use for mounting in a chassis?

It follows the ATX form factor, so it fits standard ATX mounting holes and cut-outs in compatible cases.

Which cables must be connected during installation, and which step is most often missed?

Attach the 24-pin ATX main cable and the 4+4-pin CPU power cable; the CPU power lead near the socket is the one most frequently forgotten.

What ongoing maintenance does the Zero RPM fan mode require?

Periodically clean dust from the fan intake and exhaust vents so the semi-passive cooling can still move air when the fan spins up.
