550W ATX Power Supply for Modern PCs

This KHACHIMO unit delivers 550 watts of continuous power in a standard ATX form factor. It is designed for desktop builders who need a reliable, gold-rated supply for a mid-range system. The new condition ensures full component life from first power-on.

80 PLUS Gold efficiency cuts heat and noise

The 80 PLUS Gold certification guarantees high efficiency across typical loads, lowering electricity draw and reducing waste heat. Resonant LLC topology with DC-to-DC conversion provides clean, stable power rails and minimises coil whine for quieter operation.

Modern Standby and Zero RPM simplify setup

Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency for supported motherboards. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running. Ensure the case has standard ATX clearance and that the motherboard supports the required sleep states.
