550W ATX PSU for modern builds

This KHACHIMO power supply delivers 550 watts through a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency and uses resonant LLC topology with DC-to-DC conversion to provide clean, consistent power. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency.

Suited for quiet ATX systems.

The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent operation, making it a good match for noise-sensitive builds. The DC-to-DC design also reduces coil whine for quieter running. Systems requiring more than 550 watts of continuous power should consider a higher-capacity unit.

80 PLUS Gold certified efficiency

The 80 PLUS Gold rating confirms high-efficiency operation that lowers power consumption, reduces noise and keeps temperatures cooler under typical loads. This certification is the key specification for judging whether the unit meets your efficiency and thermal expectations.
