KHACHIMO 550W ATX Power Supply

This 550 watt ATX power supply is built for desktop systems that require reliable, efficient power delivery. It suits builders who value low noise and reduced energy waste in everyday computing workloads.

Upgrade from lower-efficiency units

Replacing an older non-certified or bronze-rated supply with this 80 PLUS Gold unit cuts power draw and heat output. The jump is worth it when you want Modern Standby support for faster wake times and quieter operation under light loads.

550 watt capacity for mainstream builds

The 550W rating comfortably handles typical mid-range components including a single discrete graphics card. It runs out of headroom in configurations with multiple high-power GPUs or heavily overclocked CPUs that demand sustained output above this level.

Perguntas sobre este artigo

Will this ATX power supply fit the standard mounting holes in my case?

Yes, it uses the ATX form factor so it aligns with the standard four-screw mounting pattern used by most cases.

Which cables must be connected during installation to enable Modern Standby wake-up?

Connect the 24-pin ATX motherboard cable and the 4-pin or 8-pin CPU power cable; the firmware handles Modern Standby signalling through those rails.

If the fan stops spinning under light load, does that mean the unit needs service?

No, Zero RPM Fan Mode intentionally stops the fan at low and medium loads; it will restart automatically when temperature or load increases.
