KHACHIMO 300W ATX Switching Power Supply

300 W ATX power supply for basic builds

This new KHACHIMO unit delivers 300 W of continuous power through a standard ATX form factor. It suits office PCs, entry-level workstations or replacement jobs where the original supply has failed. The supplier confirms each unit is tested and working before shipment. Buyers who need higher wattage for discrete graphics cards or multi-drive arrays should look elsewhere.

Thermals, noise and power draw in normal use

The switching design converts mains power efficiently, keeping waste heat low during typical office workloads. Fan speed ramps only when internal temperatures rise, so acoustics stay modest under light loads. At full 300 W output the unit draws more current from the wall, but normal use rarely reaches that ceiling. No specific decibel or temperature figures are provided by the supplier.
