KHACHIMO 500W ATX Gold PSU

The KHACHIMO 500W ATX power supply delivers 80 PLUS Gold certified efficiency for desktop PCs and workstations that demand reliable, low-noise power. It fits standard ATX layouts and supports Modern Standby for rapid wake-from-sleep responsiveness.

Sustained-load behaviour

Resonant LLC topology with DC-to-DC conversion maintains clean, consistent voltage rails during extended workloads, reducing coil whine and keeping temperatures lower. The zero RPM fan mode keeps the cooling fan off at low and medium loads, activating only when thermal demand rises.

Compatibility checklist

Verify that your chassis accepts a standard ATX form-factor unit and that the cable complement matches your motherboard, GPU and storage connectors. Confirm the 500W capacity aligns with your system's total power draw before ordering.

Questions about this item

How quiet is the 500 W unit when the system runs all day under typical loads?

The Zero RPM fan mode stops the fan completely at low and medium loads, so the PSU runs silently during everyday use.

Which cables or connectors must my build already provide for this ATX power supply to work?

It uses the standard ATX 24-pin motherboard connector plus the usual CPU and peripheral cables found on any modern desktop build.

Will the 80 PLUS Gold efficiency and LLC topology cause issues with older components I keep in the same PC?

The resonant LLC design with DC-to-DC conversion delivers clean, stable power that is fully compatible with legacy hardware.
