KHACHIMO POE S5720 500W ATX Power Supply

This 500W ATX power supply is built for modern desktop PCs that prioritise quiet, efficient operation. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep transitions. The resonant LLC topology with DC-to-DC conversion delivers stable, clean power to all components. A Zero RPM fan mode keeps the unit silent at low and medium loads.

Ideal for quiet workstations and modern sleep states

System builders who value low noise and high efficiency at typical desktop loads will appreciate the Gold-rated platform and fan-stop behaviour. Modern Standby support makes it a strong match for PCs that frequently enter and exit low-power sleep. Buyers who need more than 500W of continuous output for high-end multi-GPU configurations should consider higher-capacity units.

500W continuous output rating

The single specification that determines suitability is the 500W maximum continuous power rating. This figure defines the total load the unit can sustain across all rails. Verify that the combined power draw of your CPU, GPU, drives and peripherals stays within this limit before purchasing.

Questions about this item

What case clearance is needed for an ATX power supply of this length?

The unit follows the ATX form factor, so any chassis with a standard ATX PSU bay and enough depth for the cables will accept it.

How do I enable the Zero RPM fan mode during installation?

Zero RPM activates automatically at low and medium loads; no BIOS or software setting is required — just connect the 24-pin ATX, CPU and PCIe cables securely.

How often should dust be cleared from the fan intake to keep Zero RPM effective?

A quick blast of compressed air through the rear grille every six to twelve months prevents dust build-up that could stop the fan spinning down.
