  • Product typeATX
  • Faster wake-from-sleep with Modern Standby support
  • Lower energy draw thanks to 80 PLUS Gold efficiency
  • Near-silent running through Zero RPM fan mode
  • Cleaner power delivery via resonant LLC with DC-to-DC

350 W ATX power supply

The KHACHIMO CPB09-001B delivers 350 W of continuous power in a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Suitable for efficient low-power builds

This unit suits office PCs, compact workstations or home servers that stay within a 350 W envelope and benefit from Gold-rated efficiency. The Zero RPM fan mode keeps the system near-silent at low and medium loads. Builders who need higher wattage for discrete graphics cards or multi-GPU configurations should look at larger-capacity units instead.

Fits standard ATX layouts

The ATX design fits mainstream cases and motherboards that accept a regular ATX power supply. High efficiency and low-load optimisation reduce waste heat, easing case airflow requirements. DC-to-DC conversion supports modern sleep states, freeing the builder from concerns about compatibility with newer power-management features.

Questions about this item

Does my motherboard need an ATX 24-pin connector for this 350W unit?

Yes, the power supply uses the ATX form factor and provides a standard 24-pin motherboard connector.

Will the Zero RPM fan mode stay silent when I keep my older low-power CPU?

At low and medium loads the cooling fan switches off entirely, so an older low-power CPU will typically keep the unit in silent operation.

How can I verify the 80 PLUS Gold efficiency is active after installation?

The PSU will run cooler and draw less power from the wall at typical loads; you can confirm by measuring lower AC wattage versus DC output with a power meter.
