  • TypeATX
  • Fast wake-from-sleep with Modern Standby support

  • Fan stops completely at low and medium loads
  • Resonant LLC topology with DC-to-DC reduces coil whine

500W ATX Gold PSU for modern builds

The KHACHIMO YM-7501B delivers 500W of continuous power through an ATX form factor with 80 PLUS Gold certification. Its Resonant LLC topology and DC-to-DC conversion supply clean, stable voltage rails for dependable system operation. Modern Standby compatibility ensures rapid wake-from-sleep response for supported platforms.

Sustained-load behaviour with silent operation

Under continuous demand the unit maintains high efficiency, reducing waste heat and keeping internal temperatures lower. The Zero RPM fan mode keeps the cooling fan stationary at low and medium loads, eliminating acoustic noise during typical desktop workloads. Resonant LLC design further suppresses coil whine for quieter long-running sessions.

Replaces older Bronze or non-Modern Standby units

This supply upgrades systems still running on lower-efficiency Bronze units or designs lacking Modern Standby support. The jump is worthwhile when faster sleep-wake cycles, quieter low-load operation and Gold-class efficiency are priorities. Builds that do not require Modern Standby or Zero RPM silence will not benefit from the added features.

Questions about this item

How much noise and heat does the 500 W unit produce when running all day?

The 80 PLUS Gold certification means high efficiency, which lowers power draw, reduces heat output and keeps fan noise down during extended use.

What must my system already have for the YM-7501B to work?

It is an ATX-type supply, so the chassis needs an ATX mounting space and the motherboard must accept ATX power connections.

Will the Zero RPM fan mode stay quiet with the older hardware I keep?

At low and medium loads the fan stops completely, giving near-silent operation regardless of the age of the other components.
