KHACHIMO CRPS 300W ATX Power Supply

This 300W ATX switching power supply is built for desktop systems that require a compact, efficient power source. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep performance. The Resonant LLC topology with DC-to-DC conversion delivers clean, stable output while reducing coil whine.

Suits builders wanting high efficiency

The Zero RPM fan mode keeps the unit silent at low and medium loads, making it ideal for noise-sensitive workstations or home office PCs. Systems that demand higher continuous wattage or multiple high-power graphics cards should look at a higher-capacity unit instead.

300W maximum output decides fit

With a 300W rating, this supply powers mainstream CPUs and single mid-range GPUs comfortably. Builds that plan heavy overclocking, dual-GPU configurations or many storage drives will exceed this limit and need a larger power supply.

商品問答

Does my motherboard need a 24-pin ATX socket for this 300 W unit?

Yes, the supply follows the ATX form factor and requires a 24-pin main power socket on the motherboard.

Will the 80 PLUS Gold certified 300 W supply work reliably with an older motherboard that only has a 20-pin main connector?

No, the ATX design expects a 24-pin motherboard socket; a 20-pin board would need an adapter that is not included.

How can I confirm the Zero RPM fan mode is active after I build the system?

Under light load the fan should stop spinning completely; you can verify visually or by listening for silence at idle.
