KHACHIMO HK400-56FP 300W ATX Power Supply

300W ATX Power Supply

The KHACHIMO HK400-56FP is a 300 watt ATX power supply built for entry-level desktop builds and system upgrades. It targets users who need reliable power for basic components and modern standby sleep states. This unit suits home or office PCs where high-wattage output is not required.

80 PLUS Gold Efficiency

The single specification that decides fit is the 80 PLUS Gold certification, which guarantees high efficiency at typical loads. This rating means lower power draw, reduced heat, and quieter operation compared to lower-rated units. Buyers who need more than 300 watts for discrete graphics cards or multi-drive arrays should look elsewhere.

Straightforward ATX Installation

Installation follows standard ATX mounting and cabling, so it fits most chassis designed for this form factor. The Zero RPM fan mode eliminates noise at low and medium loads, while the resonant LLC topology with DC-to-DC conversion minimises coil whine. Ensure your build’s total power draw stays within the 300 watt limit to avoid instability.
