KHACHIMO

KHACHIMO 460W 1U 80 Plus Gold Power Supply

SKU CH-X7P3-99362

A 460 W 1U ATX power supply with 80 Plus Gold efficiency, Modern Standby support, zero-RPM fan mode and LLC resonant topology for clean, quiet power delivery

  • TypeATX
  • 80 PLUS Gold certified for lower power consumption and cooler operation
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and reduces coil whine
  • Modern Standby compatible for extremely fast wake-from-sleep times and better low-load efficiency
  • 460 W output in a 1U form factor fits compact server and workstation chassis

1U Gold Efficiency for Rack Builds

This KHACHIMO 460W unit fits a standard 1U rack form factor and carries 80 PLUS Gold certification. It targets system integrators and IT professionals who need reliable, efficient power in dense server or workstation chassis. The ATX design supports modern standby for rapid wake-from-sleep behaviour.

Replaces 350W and 601UG Units

The supply is listed as a direct replacement for FSP350-60LK, FSP460-601UG and FSP460-601U models. The upgrade is worthwhile when a chassis demands higher continuous output or Gold-level efficiency to reduce operating cost and thermal load. Resonant LLC topology with DC-to-DC conversion delivers cleaner power rails for sensitive components.

460W Continuous with Silent Low-Load Operation

At full rating the unit delivers 460W of continuous power for multi-drive arrays and multi-core CPUs. Zero RPM fan mode stops the fan completely at low and medium loads, eliminating noise in idle or light-workload scenarios. Headroom diminishes when multiple high-draw GPUs or heavy peripheral loads are added beyond the rated capacity.

Questions about this item

What chassis depth and form factor does this 1U 460W unit require?

The supply is a 1U ATX form-factor module; it fits standard 1U server or rackmount chassis that accept a 1U PSU.

Which cables must be connected during installation to enable Modern Standby fast wake?

Connect the 24-pin ATX main connector, the 4- or 8-pin CPU power cable, and ensure the motherboard’s 5 V standby rail is wired; the PSU’s Modern Standby support then handles low-load wake automatically.

What component should be monitored over time to keep Zero RPM mode working?

The internal cooling fan — if bearing noise appears or the fan fails to spin up under load, the fan assembly will need replacement to restore silent operation.
