150W ATX Power Supply

The KHACHIMO PS-150 PSA-1509U is a 150W ATX power supply built for compact or low-power systems. It suits office workstations, thin clients, or embedded builds that do not demand high wattage. The unit carries an 80 PLUS Gold certification for efficient energy use. Buyers needing more headroom for discrete graphics cards or multi-drive arrays should look elsewhere.

Build Integration && Efficiency

Its ATX form factor allows installation in standard chassis designed for this size. The resonant LLC topology with DC-to-DC conversion delivers clean power to modern components while supporting deeper sleep states. Modern Standby compatibility enables extremely fast wake-from-sleep times. The 80 PLUS Gold rating helps reduce overall system power draw and heat output.

Sustained Load Behaviour

Under continuous load the unit maintains stable output thanks to its resonant LLC design with DC-to-DC conversion. This topology reduces coil whine for quieter operation during extended sessions. The zero RPM fan mode keeps the cooling fan off at low and medium loads for near-silent running. At higher sustained loads the fan engages to manage temperatures effectively.
