600W ATX Power Supply

The KHACHIMO SMQ600PS24-C is a new 600W ATX power supply built for desktop PCs. It carries 80 PLUS Gold certification for high-efficiency operation. Modern Standby compatibility enables extremely fast wake-from-sleep times and improved low-load efficiency. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power.

Suited for efficient, quiet builds

This unit suits builders who want lower power consumption, less noise, and cooler temperatures at typical loads. The Zero RPM fan mode stops the fan entirely at low and medium loads for near-silent operation. It is not for systems that demand more than 600W of continuous power or require specialised server-grade redundancy features.

600W capacity and headroom

The 600W rating comfortably handles mainstream CPUs and mid-range graphics cards during gaming or content creation. Efficiency peaks around 80% load, keeping heat and fan noise minimal in daily use. Headroom diminishes when overclocking high-end components or running sustained maximum loads across multiple rails.

Questions about this item

What motherboard power connector does this ATX supply need to work?

It uses the standard 24-pin ATX connector plus a 4+4-pin CPU power cable; check that your board has both sockets.

Will the 80 PLUS Gold efficiency and Zero RPM fan mode still function on a system built around an older platform?

Yes, efficiency certification and the semi-passive fan curve operate independently of platform age; the supply simply follows the load it sees.

How can I confirm the fan is behaving correctly after installation?

Under light load the fan should stay completely still — Zero RPM mode — and spin up only when the load rises past the medium threshold.
