KHACHIMO 80Plus Gold 400W ATX Power Supply Power85

Efficient 400 W ATX Power Supply

This 400 W ATX power supply delivers 80 PLUS Gold certified efficiency for lower power draw, reduced heat and quieter running. It suits builders assembling office PCs, home-theatre systems or modest gaming rigs that do not demand high-wattage components. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. The unit is new and ready for immediate installation.

Resonant LLC Topology with DC-to-DC Conversion

Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine for quieter operation and enabling more energy-efficient sleep states. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running during everyday tasks. Standard ATX dimensions ensure straightforward mounting in most cases. Cabling follows the usual ATX connector layout.

Upgrade from Lower-Efficiency Units

Replacing an older or lower-efficiency supply with this Gold-rated model cuts energy waste, lowers system temperatures and reduces audible noise thanks to the fan-stop feature. The jump is worthwhile when building a Modern Standby system that requires fast wake times and stable low-load power delivery. It is not suited for configurations needing more than 400 W of continuous power or multiple high-end graphics cards. Builders requiring higher wattage should consider larger-capacity units.
