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.

Perguntas sobre este artigo

What does 80 PLUS Gold certification mean for this 300W PSU?

The 80 PLUS Gold rating confirms high efficiency at typical loads, reducing power consumption, fan noise and operating temperature compared with lower-rated units.

What are the physical mounting requirements for this TFX power supply?

This is a TFX form-factor unit, so it fits slim or small-form-factor cases that accept TFX supplies and uses the standard four-screw mounting pattern.

How is the PSU installed and which step do builders often miss?

Mount the unit in the case, connect the 24-pin ATX, CPU and peripheral cables, then ensure the AC power switch on the rear is set to on before pressing the case power button.
