600W ATX power supply for modern standby PCs

The KHACHIMO SMC600PS24-C delivers 600 watts of continuous power in a standard ATX form factor. It is designed for desktop builders who want efficient energy use and support for modern standby sleep states. The unit suits systems that prioritise low idle consumption and quick wake times.

Sustained load behaviour

Under continuous demand the resonant LLC topology with DC-to-DC conversion keeps voltage regulation tight and reduces coil whine. The 80 PLUS Gold rating means less waste heat reaches the chassis during long work or gaming sessions. Lower internal temperatures also help the fan stay inactive for longer periods.

Zero RPM fan mode for silent low-load operation

At light and medium loads the cooling fan stops completely, removing audible noise from the system. This feature directly decides whether the unit fits a quiet-focused build where acoustic output at idle must be near zero. Builders who need active cooling at all loads should consider a different design.

Questions about this item

How loud and hot does the KHACHIMO SMC600PS24-C get when running all day under load?

The 80 PLUS Gold certification means high efficiency, which reduces waste heat and keeps temperatures lower. A Zero RPM fan mode stops the fan completely at low and medium loads for near-silent operation, and the resonant LLC topology with DC-to-DC conversion cuts coil whine for quieter running.

What must my PC already have so this 600W ATX unit will power on and run?

It fits a standard ATX case cut-out and connects to a motherboard 24-pin socket and CPU power connector; your case needs room for an ATX-length supply and your motherboard must accept those standard power headers.

Will this supply work reliably with older components I plan to keep, such as a legacy motherboard or graphics card?

Modern Standby compatibility enables faster wake-from-sleep and efficient low-power states used by newer platforms, while the DC-to-DC conversion and LLC resonant topology deliver clean, stable voltages that older parts also require, so it supports both current and legacy hardware.
