450W ATX power supply for mainstream builds

The KHACHIMO HK550-35FP delivers 450 watts of continuous power through a standard ATX form factor. It targets builders assembling office PCs or entry-level gaming rigs that do not demand high-wattage headroom. The unit carries an 80 PLUS Gold certification for efficient energy conversion.

Fits standard ATX cases with modern standby support

The supply uses resonant LLC topology with DC-to-DC conversion to provide clean voltage rails for modern components. Modern Standby compatibility enables extremely fast wake-from-sleep transitions and improved low-load efficiency. Zero RPM fan mode stops the fan entirely at low and medium loads for silent operation.

Sustained output at Gold efficiency

Under continuous load the Gold-rated design keeps power draw lower and temperatures reduced compared to lower-rated units. The resonant LLC topology and DC-to-DC conversion maintain stable voltages while minimising coil whine. The fan remains off until higher thermal thresholds are reached.
