TFX Power 3 300W Bronze: the upgraded be quiet! PSU for mini and media PCs with 80 PLUS® Bronze certification and PCIe graphics card support.
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.
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.
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.
