  • Product typeATX
  • Faster wake from sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Zero RPM fan mode stops the fan at low loads
  • Resonant LLC and DC-to-DC topology delivers cleaner power

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.

Questions about this item

What does the 80 PLUS Gold certification mean for the Power85's efficiency in practice?

The 80 PLUS Gold rating means the Power85 meets high efficiency standards at typical loads, reducing power waste, heat output, and fan noise compared to lower-rated units.

What physical space and mounting does the Power85 require in a case?

The Power85 uses the standard ATX form factor, so it fits any case with an ATX power supply bay and mounts with four screws at the rear.

How do I install the Power85 and enable its Zero RPM fan mode?

Mount the unit, connect the 24-pin motherboard and CPU power cables, then plug in the AC cord; Zero RPM mode activates automatically at low and medium loads.
