600W ATX power supply for modern PCs

The KHACHIMO HG2-5600V delivers 600W of continuous power through an ATX form factor, making it suitable for mainstream desktop builds and workstations. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing wasted energy and heat output. Modern Standby compatibility allows extremely fast wake-from-sleep transitions and improved low-load efficiency for systems that use connected standby states. This unit targets builders who want reliable power with quiet operation.

Gold efficiency and zero-fan headroom

At low and medium loads the Zero RPM fan mode stops the cooling fan completely, providing near-silent operation during everyday tasks. The Resonant LLC topology with DC-to-DC conversion supplies clean, consistent power while reducing coil whine and enabling deeper sleep states. Efficiency remains high up to the rated 600W, but sustained loads beyond that ceiling will exceed the unit's capacity and require a higher-wattage supply. Builders planning heavy overclocking or multi-GPU configurations should look elsewhere.

ATX fit with Modern Standby support

The standard ATX dimensions allow installation in most mid-tower and larger cases without special brackets. Modern Standby support means the PSU works correctly with motherboards and operating systems that implement connected sleep, freeing the builder from compatibility guesswork on wake times. The DC-to-DC design simplifies cable routing by generating minor rails efficiently, leaving more room for airflow around the GPU and CPU coolers. Systems needing server-grade redundancy or non-ATX form factors are not addressed by this model.

Questions about this item

Will the Zero RPM fan mode stay quiet with my older low-power components?

The fan remains off at low and medium loads so older parts that draw little power will not spin it up.

How do I confirm the 80 PLUS Gold efficiency is active after install?

You will notice lower power draw, less heat and quieter running compared with a non-certified unit.

Does the box include every cable I need for a standard ATX build?

The unit ships with the fixed ATX cables required for a typical build; no extra cables are needed.
