KHACHIMO 600W ATX power supply

This 600W ATX unit targets builders who want efficient, quiet power for mid-range desktop systems. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep behaviour.

Build fit and clearances

The PSU uses Resonant LLC topology with DC-to-DC conversion to deliver clean output and reduce coil whine. Its Zero RPM fan mode stops the fan completely at low and medium loads, freeing the build from audible spinning noise during light work.

Buyer fit and limits

This unit suits users who prioritise low idle noise and high efficiency in a standard ATX form factor. Builders needing higher wattage for multi-GPU configurations or extreme overclocking headroom should consider larger capacity models.

Questions about this item

What is the first limit reached under sustained load?

The power supply delivers up to 600 W continuously, so the first limit is the total output power rating.

How does the unit handle noise and heat during all-day operation?

Zero RPM mode stops the fan at low and medium loads, while 80 PLUS Gold efficiency reduces waste heat and keeps temperatures lower.

What must the system already have for this PSU to work?

A standard ATX case and motherboard with 24-pin and CPU power connectors are required for installation.
