600W ATX power supply for quiet builds

The KHACHIMO SMQ600PS27-C delivers 600 watts of continuous power in a standard ATX form factor. It targets system builders who want reliable output with minimal acoustic intrusion during everyday workloads.

80 PLUS Gold efficiency replaces lower-rated units

Moving from a standard or Bronze-rated supply to this Gold-certified model cuts waste heat and reduces coil whine through resonant LLC topology with DC-to-DC conversion. The upgrade pays off when the system spends long periods at idle or light load where efficiency gaps widen.

Modern Standby and zero-RPM headroom

The unit supports Modern Standby for rapid wake times and keeps its fan stopped at low to medium loads, giving silent operation for office tasks and media playback. Heavy sustained loads will spin the fan and push the 600W limit, so builds with high-end graphics cards or overclocked CPUs need a higher-capacity model.

Questions about this item

What ATX case clearance does this 600W unit require?

It follows the standard ATX form factor, so any case with an ATX PSU bay will accept it.

Which cables must be connected during installation to enable Modern Standby?

Plug the 24-pin ATX, the 8-pin EPS, and the PCIe connectors; the motherboard then handles the low-power handshake automatically.

When should the fan bearing be checked on this Gold-rated supply?

The Zero RPM mode keeps the fan off at low load, so bearing wear is minimal; listen for noise if the fan spins up under heavy load.
