Silver 1U rack power supply unit with rear fan grille and IEC inlet

KHACHIMO

KHACHIMO I610-G10 1U 600W Power Supply PWS-605P-1H

SKU CH-RC8C-FHZ4Y

A 1U ATX unit delivering 600W with 80 PLUS Gold efficiency, zero-RPM fan mode for silent low-load operation, and resonant LLC topology with DC-to-DC conversion for clean power

  • Product typeATX
  • Modern Standby compatible for extremely fast wake-from-sleep
  • 80 PLUS Gold certified for lower power consumption and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads
  • Resonant LLC topology with DC-to-DC conversion reduces coil whine
  • 600W ATX power supply in a 1U form factor

Compact 1U 600W ATX power supply

This 1U form-factor unit delivers 600W of continuous power in a height suited to rack-mount and shallow chassis builds. It targets system integrators and enthusiasts assembling dense servers, workstations or compact PCs where vertical space is at a premium. The ATX electrical layout keeps cabling compatible with standard motherboards and backplanes.

80 PLUS Gold efficiency with Zero RPM mode

Gold-rated efficiency reduces waste heat and lowers operating cost across typical load ranges. Below medium load the fan stops completely, eliminating acoustic noise during idle or light compute tasks. Resonant LLC topology paired with DC-to-DC conversion tightens voltage regulation and suppresses coil whine for cleaner power delivery.

Modern Standby sleep-state support

The platform enables rapid wake-from-sleep transitions and deeper low-power states supported by Modern Standby hardware. Builds that rely on legacy S3 sleep or that lack firmware support for the newer sleep protocol will not benefit from the fast-resume capability. The 1U height also limits use in towers that require full-height PSU brackets.

Questions about this item

Will the fan need replacement if the Zero RPM mode cycles on and off repeatedly?

The Zero RPM Fan Mode stops the fan at low and medium loads, reducing mechanical wear compared to constant spinning.

What limits sustained output before protection triggers?

The unit delivers up to 600 W; sustained loads at or near that level will hit the over-power protection threshold first.

How loud and hot does it run during all-day operation?

80 PLUS Gold efficiency keeps waste heat low, and Zero RPM mode keeps noise near zero at typical loads.
