Khachimo VX300 300W ATX Power Supply

This Khachimo VX300 is a 300 W ATX power supply rated for 400 W peak output. It carries 80 PLUS Gold certification and uses resonant LLC topology with DC-to-DC conversion for stable voltage delivery. Modern Standby compatibility enables fast wake times and improved low-load efficiency. The unit targets compact or entry-level builds that need efficient, quiet power.

Zero RPM Fan Mode for Silent Operation

The Zero RPM fan mode stops the cooling fan completely at low and medium loads, making it suited for noise-sensitive environments such as home offices or media PCs. Builders who need higher continuous wattage for discrete graphics cards or multi-drive arrays should consider a higher-capacity model instead.

300 W Continuous / 400 W Peak Rating

The single specification that determines fit is the 300 W continuous rating with a 400 W peak limit. Verify that the total system draw under full load stays within 300 W before selecting this unit.
