400W ATX Gold Power Supply

The KHACHIMO FSP unit delivers 400 watts of continuous power in a standard ATX form factor. It targets system builders who need an efficient, low-noise supply for compact or mainstream desktop configurations.

Build quality and daily implications

80 PLUS Gold certification ensures high efficiency across typical loads, reducing waste heat and keeping internal temperatures lower. Zero RPM fan mode stops the fan completely at low and medium loads, providing near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while minimising coil whine.

Modern Standby and bundled benefits

Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency for systems that support the feature. The combination of Gold-rated efficiency, fan-stop behaviour and quiet topology reduces both noise and power draw without requiring additional software or accessories.
