KHACHIMO 300W ATX Power Supply

The KHACHIMO 300W ATX unit delivers 300 watts of continuous power through a 10-pin connector layout. It is built for small-form-factor desktops and office workstations that require efficient, reliable energy conversion.

Capacity and headroom

The 300W rating provides comfortable headroom for integrated graphics, entry-level discrete cards and typical office workloads. Systems drawing sustained loads above 300 watts will exceed the unit's capacity and require a higher-rated supply.

Thermals, noise and power draw

80 PLUS Gold certification ensures high efficiency, reducing waste heat and overall power draw. Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion minimises coil whine and supports modern standby sleep states.

Questions about this item

Will the 10-pin ATX connector on this 300 W unit fit the proprietary motherboard header I already have?

The power supply uses a 10-pin ATX connector; verify that your motherboard has the matching 10-pin header before installation.

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

Under light loads the fan should stop spinning completely; you can visually check the fan or monitor RPM in the BIOS or software to confirm it reads zero.

Are the 80 PLUS Gold certification badge and Modern Standby compatibility logo printed on the retail box?

Yes, the packaging displays the 80 PLUS Gold badge and Modern Standby compatible markings to confirm the certified efficiency and sleep-state support.
