Characteristics
80 PLUS® BRONZE CERTIFICATION
Efficient operationThe 80 PLUS Bronze certification with an efficiency rating of up to 87% is convincing evidence of this PSU’s power saving operation.
STRONG DUAL 12V RAIL
For a stable operationThe dual 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. Safety protections defend against overcurrents, over- and undervoltages, short circuits and overloads, thus keeping your valuable components safe.
“We at be quiet! have a heart for mini and media PCs. TFX Power 3 is our love letter to those systems and it makes me happy to know, how many of them are equipped in such compact systems all over the world."
