TFX 300W power supply for compact builds

The KHACHIMO SSP-300TGS is a TFX form-factor unit rated at 300 W, designed for slim desktops and small-form-factor enclosures where standard ATX supplies cannot fit. It carries 80 PLUS Gold certification for high efficiency and supports Modern Standby for rapid wake times.

Straightforward TFX installation with fan-off mode

Installation follows the usual TFX mounting pattern: four screws secure the unit and the 24-pin, CPU and peripheral cables route to the motherboard and drives. The Zero RPM fan mode stops the fan at low and medium loads, so unexpected silence is normal behaviour, not a fault.

Check TFX clearance and cable reach before ordering

Verify that your chassis accepts a TFX supply and that the fixed cable lengths reach every connector in your layout. Builds requiring higher wattage or modular cabling will need a different solution.
