SFX Power 3 300W, the first choice compact PSU for mini and media PCs with 80 PLUS® Bronze and PCIe graphics card support. SFX Power 3 300W offers the ideal combination of power, quietness and reliability.
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.
The SFX Power 3 can deliver 300W of continuous power. This ensures a steady and reliable operation even when your PC meets an unexpectedly heavy load.
The high-quality temperature-controlled 80mm fan allows quiet operations of max. 29.4dB(A). The 80 PLUS Bronze certification with an efficiency rating of up to 89.2% is convincing evidence of this PSU’s power saving operation.
