KHACHIMO 300W ATX Gold PSU

The KHACHIMO 300W ATX power supply delivers 80 PLUS Gold certified efficiency for desktop systems. It features Modern Standby compatibility for extremely fast wake-from-sleep transitions and improved low-load efficiency. A Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine. The unit suits builders wanting efficient, quiet operation in a standard ATX form factor.

Ideal for quiet, efficient desktop builds

This unit suits builders who prioritise low noise and high efficiency in a 300W ATX power supply. Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. Buyers needing more than 300 watts of continuous power should look at higher-capacity units. Systems requiring redundant or server-grade features will not find them here.

300W continuous output capacity

The single specification that decides fit is the 300W continuous output rating. Your complete system — CPU, graphics card, drives and peripherals — must draw less than this figure under full load. The 80 PLUS Gold certification ensures high efficiency at typical loads. No other wattage or form factor options are described for this model.

Questions about this item

How can I verify the PSU is running correctly after installation?

The fan stays off at low and medium loads thanks to Zero RPM mode, so silent operation confirms the unit is working within its efficient range.

What cables come attached to this 300 W ATX supply and what must I source separately?

Fixed 24-pin ATX and 4+4-pin CPU leads are provided; any additional peripheral or GPU cables need to be purchased if your build requires them.

Which of the 610L or 610H versions should I choose for my system?

Both 610L and 610H share the same 300 W Gold-rated platform with Modern Standby and LLC-DC-DC topology; pick the one that matches your chassis mounting or cable-routing preference.
