550W / 600W ATX Power Supply

The KHACHIMO ATX power supply delivers 550W or 600W of continuous power for standard desktop builds. It carries 80 PLUS Gold certification for high efficiency, lower power draw and reduced heat. Modern Standby compatibility enables extremely fast wake-from-sleep times and better low-load efficiency. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power and reduces coil whine.

Builders wanting efficient, quiet ATX power

Suits system integrators and upgraders who need an ATX unit with 80 PLUS Gold efficiency and a zero-RPM fan mode for near-silent operation at low and medium loads. Not for compact chassis requiring SFX or TFX form factors. Not for workstations or multi-GPU rigs that demand higher wattage than 600W.

80 PLUS Gold efficiency rating

The 80 PLUS Gold rating confirms high-efficiency operation across typical loads, cutting power consumption, noise and temperatures. Zero RPM fan mode keeps the fan off entirely at low and medium loads for silent running. Resonant LLC topology with DC-to-DC conversion supports modern sleep states and stable voltage delivery.

Questions about this item

Does the ATX form factor fit a standard ATX case?

Yes, the unit follows the ATX form factor so it mounts in any standard ATX chassis using the four rear screws.

Which cables must be connected for a basic install, and what is the common mistake?

Connect the 24-pin motherboard cable and the 8-pin CPU cable; the step often missed is seating both connectors fully until the clips click.

What maintenance does the Zero RPM fan need over time?

The fan stops at low load, so dust builds more slowly; clean the intake grill with compressed air once a year to keep airflow clear.
