80 PLUS® Bronze Certification

Efficient operation

The 80 PLUS Bronze certification of TFX Power 3 300W Bronze with an efficiency rating of up to 88.3% is convincing evidence of this PSU’s power saving operation.

Strong Single 12V Rail

For maximum power

The 12V rail design supports high stability as the CPU receives its power through an independent rail. For demanding peripherals like a graphics card, a PCIe connector is included.  This makes the TFX Power 3 300W Bronze the ideal PSU for all who strive for enough power to support small systems at low noise.

Quiet And Safe

Optimized for low-noise operation

The temperature-controlled fan ensures a quiet operation and produces little wasted heat.  Since TFX Power 3 300W Bronze meets the latest safety requirements, it defends the PC system against overcurrents, over- and undervoltage, short circuit, overloads and comparable failures.
