STRONG DUAL 12V RAIL

For a stable PCIe graphics support

The dual 12V rail design supports high stability as the CPU receives its power through an independent rail. A PCIe connector provides power for a demanding graphics card. Safety protections defend against overcurrents, over- and undervoltages, short circuits and overloads, thus keeping your valuable components safe.

400 WATTS CONTINUOUS POWER OUTPUT

Ensures a steady and reliable operation

The SFX Power 2 can deliver 400W of continuous power. This ensures a steady and reliable operation even when your PC meets an unexpectedly heavy load.

80 PLUS® BRONZE CERTIFICATION

Efficient operation

The 80 PLUS Bronze certification with an efficiency rating of up to 89% is convincing evidence of this PSU’s power saving operation.

“Users with mini ITX PCs or overall compact systems also deserve a quiet and powerful PSU with up to 80PLUS® Gold efficiency. With this in mind, we have developed the SFX Power series. To all whom it concerns: you are welcome.”
