KHACHIMO PA-2301-3 D17-300P2A 300W ATX power supply

300W ATX power supply for compact builds

The KHACHIMO PA-2301-3 D17-300P2A delivers 300 watts of continuous power in a standard ATX form factor. It targets system integrators and DIY builders who need reliable, efficient energy delivery for small-form-factor or office-oriented PCs. The unit supports Modern Standby for rapid wake-from-sleep behaviour.

80 PLUS Gold efficiency with Zero RPM fan mode

Gold certification means the supply runs at high efficiency across typical loads, reducing waste heat and lowering overall power draw. The Zero RPM mode stops the fan completely at low and medium loads, eliminating acoustic noise during light desktop work or media playback. Resonant LLC topology with DC-to-DC conversion further suppresses coil whine and improves voltage regulation.

Clean power headroom for mainstream components

The 300W rating comfortably handles modern mid-range CPUs, integrated graphics and a single discrete GPU with modest power requirements. It leaves enough reserve for several storage drives and USB peripherals. Builds demanding multiple high-end graphics cards, extreme overclocking or sustained loads well above 300 watts will exceed this unit's capacity.
