Modern Standby ATX Power Supply

This KHACHIMO ATX power supply supports Modern Standby for extremely fast wake-from-sleep times and improved low-load efficiency. It is intended for desktop builders who want a new unit that meets 80 PLUS Gold efficiency requirements. The product is sold new and fits standard ATX chassis.

80 PLUS Gold Efficiency Rating

The single specification that determines suitability is the 80 PLUS Gold certification, which guarantees high efficiency operation for lower power consumption, less noise and cooler temperatures. Units without this rating cannot deliver the same verified efficiency at typical loads. Buyers who need a lower efficiency standard should choose a different model.

Sustained Load Behaviour

Under sustained load the resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine for quieter operation. The zero RPM fan mode keeps the cooling fan off entirely at low and medium loads for near-silent operation. This combination maintains stable output and low acoustic noise during extended use.

  • 80 PLUS Gold certification cuts power draw and heat output

Questions about this item

What does the 80 PLUS Gold rating mean for everyday power draw?

It certifies the unit runs at high efficiency across typical loads, so less electricity is wasted as heat and the system stays cooler and quieter.

Which ATX standard does this supply follow and what does that limit?

It follows the ATX form factor, which defines the physical dimensions and connector layout that determine whether it fits a standard case and motherboard.

What clearance do I need inside my case for this power supply?

The ATX form factor sets a standard width and height, so any case with a regular ATX PSU bay will accept it; check your case spec for maximum depth.
