SKU CH-AR1W-ZS36G

A 300 W ATX power supply with 80 PLUS Gold efficiency, Modern Standby support and a Zero RPM fan mode for silent low-load operation

  • Product typeATX
  • Modern Standby compatibility gives extremely fast wake-from-sleep times and better low-load efficiency
  • 80 PLUS Gold certification delivers high efficiency for lower power consumption, less noise, and cooler temperatures
  • Zero RPM fan mode stops the fan at low and medium loads for near-silent operation
  • Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine
  • DC-to-DC conversion enables more energy efficient sleep states

Compact ATX supply for 1U systems

This 300 W ATX unit fits the 1U form factor required by thin rack or slim desktop chassis. It targets builders who need a high-efficiency power source in a restricted vertical space and who value Modern Standby support for rapid wake times.

Gold efficiency with fan-stop mode

The 80 PLUS Gold rating means lower losses at typical loads, reducing both electricity draw and internal heat. A Zero RPM mode keeps the fan off at low and medium loads, so the supply runs silently during office work or idle periods.

Resonant LLC topology for clean power

Resonant LLC with DC-to-DC conversion delivers stable rails and suppresses coil whine, contributing to quieter operation. The design also enables deeper sleep states, so the system draws minimal power when suspended while still waking quickly.

Questions about this item

What does the 80 PLUS Gold certification mean for the KHACHIMO TURBO-COOL EDGE 300W?

It confirms high efficiency operation that reduces power consumption, lowers noise output and keeps temperatures cooler across typical load ranges.

What physical space is required to fit this 1U power supply?

It uses a standard 1U ATX form factor designed to mount in a single rack unit or compatible slim chassis with matching screw-hole spacing.

How is the Zero RPM fan mode activated on this unit?

The cooling fan stops automatically at low and medium loads; the step users miss is ensuring the motherboard and BIOS support the required sleep states for the feature to engage.
