350W ATX power supply for efficient builds

This KHACHIMO unit delivers 350W of continuous power in a standard ATX form factor. It is built for systems that prioritise energy efficiency and quiet operation over high-wattage headroom. The 80 PLUS Gold certification confirms high efficiency across typical loads.

Upgrade from lower-efficiency or noisy units

Replacing an older bronze-rated or uncertified supply reduces power draw, heat output and fan noise in one step. The resonant LLC topology with DC-to-DC conversion also minimises coil whine, making the jump worthwhile for noise-sensitive environments.

Suits Modern Standby PCs and quiet workstations

Builders who need fast wake-from-sleep and silent low-load running will benefit from the zero-RPM fan mode and Modern Standby compatibility. Systems requiring substantially more than 350W or auxiliary connectors not listed here should consider higher-capacity alternatives.

Questions about this item

Does this 350W ATX unit fit a standard ATX case cut-out?

Yes, it follows the ATX form factor so it will mount in any case with a standard ATX power-supply opening.

Which cables must be connected during installation, and which step is often missed?

Connect the 24-pin motherboard cable, the CPU power cable, and any GPU or drive cables required; the step most often missed is seating the 24-pin connector fully until the latch clicks.

What maintenance will the fan need over time?

The Zero RPM mode keeps the fan off at low and medium loads, so dust buildup is slower; clean the intake with compressed air once a year or when noise appears.
