300W ATX PSU for Modern Standby PCs

This KHACHIMO unit delivers 300 watts of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. The platform uses Resonant LLC topology with DC-to-DC conversion to provide clean voltage regulation and support low-power sleep states. It is built for systems that require fast wake times and quiet operation.

Suitable for compact builds needing Gold efficiency

This supply suits small-form-factor or low-power desktops that benefit from Modern Standby compatibility and a Zero RPM fan mode for silent idle running. It is not for high-performance gaming rigs or workstations that demand more than 300 watts of power. Builders needing multiple PCIe power connectors or higher peak output should look at larger units.

80 PLUS Gold certified 300W capacity

The single specification that decides fit is the 300 watt rated output combined with 80 PLUS Gold efficiency. This fixed capacity determines whether the unit can handle your components' total power draw. Verify your system's maximum consumption against this 300 watt limit before purchasing.

Questions about this item

What does the 300W rating mean for my build?

It is the maximum continuous power the unit can deliver to your components; choose it when your total system draw stays comfortably below that figure.

What does 80 PLUS Gold certification mean in daily use?

It guarantees higher efficiency across typical loads, so less electricity is wasted as heat and the fan can stay off longer.

How does the ATX form factor limit where I can install this supply?

It fits standard ATX cases and uses the usual 24-pin, CPU and peripheral connectors, so it works in any chassis designed for that layout.
