ATX power supply with 80 PLUS Gold efficiency

The KHACHIMO PQ60120QEB25NNH is an ATX power supply built for desktop PCs that demand efficient and quiet operation. It carries 80 PLUS Gold certification, meaning it converts mains power with high efficiency to reduce waste heat and lower running costs. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power and helps reduce coil whine.

Zero RPM fan mode and silent cooling

At low and medium loads the cooling fan stops completely, providing near-silent operation during everyday tasks. This Zero RPM mode works alongside the high-efficiency design to keep temperatures down without audible fan noise. The resonant LLC topology with DC-to-DC conversion further reduces coil whine, contributing to a quieter overall system. These features combine to create a power supply that remains unobtrusive in noise-sensitive environments.

Suited for quiet, efficient desktop builds

This unit suits builders who prioritise low noise and high efficiency in a standard ATX form factor. Modern Standby support benefits users who frequently put their systems to sleep and expect instant resume. Buyers needing a different wattage rating or a non-ATX form factor should look at other models. The 12 V 25 A output configuration is fixed, so systems requiring alternative rail distributions will need a different design.

Questions about this item

How often will the 12 V 25 A fan bearing need replacement under continuous load?

The fan stops completely at low and medium loads via Zero RPM mode, so bearing wear is minimal until higher loads engage active cooling.

Which protection triggers first when the 12 V rail runs at 25 A for hours?

Over-temperature protection engages before current limits, as 80 PLUS Gold efficiency keeps heat lower during sustained high-output operation.

How loud is the unit when the 12 V 25 A output runs all day in a warm case?

Zero RPM mode keeps the fan off at low and medium loads, while resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter sustained operation.
