ATX Power Supply for Modern Standby Systems

The KHACHIMO DS-KAA8402-Y is an ATX power supply built for PCs that use Modern Standby sleep states. It suits builders who want efficient, quiet power delivery for daily computing and light workloads. Its 80 PLUS Gold rating confirms high efficiency across typical loads.

Zero RPM Fan Mode and Resonant LLC Topology

At low and medium loads the cooling fan stops completely, removing audible noise during office work or media playback. The resonant LLC topology with DC-to-DC conversion supplies clean, consistent power and reduces coil whine, while also supporting deeper, more energy-efficient sleep states.

ATX Form Factor with Gold-Certified Efficiency

The unit follows the standard ATX form factor for broad case compatibility. Gold-certified efficiency lowers power draw, heat output and fan activity under load. No modular cabling or specialised connectors are listed, so cable routing follows the fixed harness supplied.

Questions about this item

Will the fan bearing on the DS-KAA8402-Y need replacement after years of continuous use?

The Zero RPM Fan Mode keeps the fan off at low and medium loads, reducing bearing wear and extending the interval before any replacement might be needed.

What limit appears first when the DS-KAA8402-Y runs at full load for hours?

The 80 PLUS Gold efficiency rating caps waste heat, so thermal limits inside the resonant LLC topology are reached before the unit hits its maximum output capability.

How much noise and heat does the DS-KAA8402-Y produce during an all-day workload?

Zero RPM mode silences the fan at typical loads, while 80 PLUS Gold efficiency and DC-to-DC conversion keep heat output low even under sustained operation.
