KHACHIMO 500W ATX Power Supply HG2-5500V HG2-5600V

500W ATX power supply for modern PCs

This 500W ATX unit delivers 80 PLUS Gold efficiency and Modern Standby compatibility for fast wake-from-sleep performance. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. The Zero RPM fan mode keeps the system near-silent at low and medium loads.

Suited for efficient mid-range builds

Builders wanting fast sleep recovery and low idle power draw will benefit from Modern Standby support and Gold-rated efficiency. The fan-stop feature suits noise-sensitive environments such as home offices or media PCs. Systems requiring higher continuous wattage or multiple high-power GPU connectors should consider a larger unit.

Zero RPM fan mode and LLC topology change daily

The fan remains off until the load rises above the medium threshold, eliminating noise during typical desktop tasks. LLC resonant conversion with DC-to-DC lowers ripple and suppresses coil whine, which improves audio clarity for sensitive headphones. Modern Standby support lets the PC enter deeper sleep states and resume almost instantly.
