KHACHIMO 500W 80 Plus Bronze SS-500ET SS-500ES ATX Power Supply

500W ATX Power Supply

The KHACHIMO 500W ATX power supply delivers 500 watts of continuous power for desktop builds. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Builders prioritising quiet operation

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation. This suits systems where acoustic output matters and where Modern Standby sleep states are used. Buyers who need higher wattage for multi-GPU configurations or extreme overclocking should look at higher-capacity units. The ATX form factor fits standard chassis designs without special mounting requirements.

Sustained-load behaviour with Gold-rated efficiency

Under sustained load the 80 PLUS Gold rating keeps efficiency high, reducing waste heat and lowering overall power draw. The resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation during prolonged operation. Zero RPM mode remains inactive once load exceeds the medium threshold, so the fan spins to manage thermals during extended heavy workloads. Coil whine is minimised by the topology choice even when the unit runs continuously at significant output.
