300 W ATX Power Supply

The KHACHIMO ATX power supply delivers 300 W of continuous output on a single 12 V rail rated at 27 A. It is built for systems that require a compact, efficient unit with modern standby support and quiet operation under typical desktop workloads. The 80 PLUS Gold certification confirms high efficiency across a wide load range.

Suited for low-power builds and silent PCs

This unit suits compact desktops, office workstations and media centres that draw modest power and benefit from fan-less operation at low and medium loads. Builders planning high-end discrete graphics, multi-drive arrays or sustained heavy compute should look elsewhere because the 300 W ceiling and single 12 V rail leave little headroom for peak demands.

Sustained load behaviour

Under continuous load the resonant LLC topology with DC-to-DC conversion maintains tight voltage regulation and suppresses coil whine. The zero-RPM fan mode keeps the unit silent until thermal thresholds rise, after which the fan spins up gradually to dissipate heat without abrupt noise spikes. Efficiency remains high, reducing waste heat during long sessions.

Questions about this item

Does my motherboard need an ATX power connector for this 300 W unit?

Yes, the power supply uses the standard ATX form factor and will connect to any motherboard with a matching ATX power socket.

Will the 12 V 27 A output support older components that draw less current on the same rail?

The single 12 V rail delivers up to 27 A, so legacy parts that require less current will operate normally within that capacity.

How can I confirm the Zero RPM fan mode is active after installation?

Under light or medium loads the cooling fan stops completely; you can verify silent operation by listening for the absence of fan noise while the system idles.
