KHACHIMO U60 Ultra60 300W ATX PSU

The KHACHIMO U60 Ultra60 is a 300W ATX power supply built for modern desktop systems. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for fast wake-from-sleep performance. A Zero RPM fan mode stops the fan at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine.

Suitable for efficient mainstream builds

This unit suits builders who want Gold-rated efficiency, silent low-load operation and Modern Standby support in a standard ATX form factor. It is not for systems that need more than 300W of continuous power or configurations requiring multiple high-draw graphics cards. Buyers needing higher wattage headroom or additional PCIe power connectors should look at larger-capacity units.

300W capacity with Gold efficiency headroom

The 300W rating comfortably handles mainstream CPUs, single mid-range GPUs and typical peripherals while maintaining high efficiency across the load range. At low and medium loads the fan stays off and efficiency stays high, keeping noise and heat down. Heavy multi-GPU arrays or overclocked high-end components will exceed the available power and connector budget.

Questions about this item

What ATX connector count does my motherboard need for the 300 W U60 to power on?

The unit uses a standard ATX design, so a 24-pin main connector plus the 4/8-pin CPU power cable from the PSU must match the motherboard headers.

Will the Zero RPM fan mode stay off when my older GPU idles alongside this supply?

Yes, the fan stops at low and medium loads, so legacy cards that draw little power at idle will not spin the PSU fan.

How can I confirm the 80 PLUS Gold efficiency is active after install?

Check that the system enters Modern Standby and wakes near-instantly; the Gold rating also means lower heat and quieter operation at typical loads.
