  • Modern Standby support gives faster wake from sleep
  • Resonant LLC plus DC-to-DC delivers clean, stable power
  • ATX 500 W unit fits standard desktop builds

500W ATX Gold power supply

This KHACHIMO CRPS unit delivers 500 watts of continuous power through a standard ATX form factor. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion for stable voltage regulation. Modern Standby compatibility enables rapid wake-from-sleep transitions. A zero RPM fan mode stops the fan completely at low and medium loads.

Suited for efficient mainstream builds.

The 500 watt rating and Gold efficiency make this supply a strong match for mid-range desktop configurations that prioritise low power draw and quiet operation. Modern Standby support benefits users who rely on fast sleep and wake cycles. Builders planning multi-GPU arrangements, heavy overclocking, or workstations that demand substantially more headroom should look at higher-capacity units instead.

Fits standard ATX layouts; frees acoustic headroom

The ATX footprint allows installation in typical tower cases without special brackets. Zero RPM mode removes fan noise during everyday tasks, reducing overall system sound levels. LLC resonant topology with DC-to-DC conversion helps minimise coil whine, contributing to a quieter environment. Modern Standby readiness lets the platform enter deeper sleep states without compatibility concerns.

Perguntas sobre este artigo

Does the 500W ATX unit need a 24-pin ATX motherboard connector to power the board?

Yes, the supply uses the standard ATX form factor so it provides the 24-pin motherboard connector along with CPU and peripheral cables required for a typical build.

Will the 80 PLUS Gold certified 500W PSU work reliably with an older motherboard that only supports legacy sleep states?

The Resonant LLC topology with DC-to-DC conversion delivers clean power compatible with older boards, while Modern Standby support simply remains unused on legacy platforms.

How can I confirm the Zero RPM fan mode is active after installing the 500W unit?

At low and medium loads the cooling fan stops completely; listen for silence and verify fan RPM reads zero in your monitoring software or BIOS hardware monitor.
