TFX 300 W PSU for Compact Builds

This TFX-form-factor unit delivers 300 W of continuous power for slim desktops and small-form-factor systems. It targets builders who need a high-efficiency supply that fits the restricted chassis space of many office and home-theatre PCs.

80 PLUS Gold with Zero RPM Fan

Gold certification means high efficiency across typical loads, reducing waste heat and lowering electricity draw. The Zero RPM mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion keeps output clean and minimises coil whine for quiet daily use.

Limits of the 300 W TFX Standard

The 300 W ceiling restricts the graphics cards and high-core-count CPUs the supply can support, so it suits integrated graphics or modest discrete GPUs only. Builders who need more power for multi-GPU arrays or heavy overclocking must choose a higher-wattage, larger-form-factor unit instead.
