300W ATX Power Supply

The KHACHIMO SP2-4300F is a 300W ATX power supply built for modern standby compatibility and efficient operation. It carries 80 PLUS Gold certification to lower power consumption, noise and running temperatures. Resonant LLC topology with DC-to-DC conversion delivers clean power and reduces coil whine. A zero RPM fan mode stops the fan at low and medium loads for near-silent performance.

Best for Low-Power Builds

This unit suits compact or office systems that need reliable ATX power with quiet operation and fast wake-from-sleep. Builders planning high-wattage GPUs, multi-drive arrays or heavy overclocking should look at higher-capacity supplies instead. Modern standby support makes it a good match for PCs that spend long periods in low-power sleep states.

300 Watt Output Limit

The single deciding specification is the 300W maximum output, which sets the total power available for every component in the system. If your planned hardware exceeds this ceiling, the supply cannot support it. Always verify the combined draw of your CPU, graphics card and peripherals against this limit before purchasing.
