KHACHIMO 1U ATX 300W Power Supply

This KHACHIMO 1U power supply delivers a rated 300W with a 450W peak for compact ATX builds. It carries 80 PLUS Gold certification and Modern Standby compatibility for efficient low-power states.

Suits space-constrained systems needing quiet

The Zero RPM fan mode and resonant LLC topology suit noise-sensitive workstations or HTPCs. It is not for high-wattage GPUs, multi-GPU configurations, or servers requiring redundant power modules.

300W continuous output decides fit

The 300W sustained rating is the single figure that determines whether this unit can power your chosen components. If your build draws more under load, you must select a higher-capacity supply.

Perguntas sobre este artigo

What motherboard power connectors does the KHACHIMO HJ-450WA require to work?

The unit provides a standard 24-pin ATX connector and a 4+4-pin EPS connector for the CPU.

Will the 300 W rated output support an older graphics card that draws power from the motherboard slot only?

Yes, the 300 W continuous rating delivers ample headroom for slot-powered cards and legacy components.

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

Under light loads the fan stops spinning completely; you can verify silence visually or by ear at idle.
