Corsair SF Series SF450 SFX Power Supply overview

SF Series power supplies bring legendary Corsair performance and reliability to the SFX small form factor standard. They have the features found in full-size high performance power supplies, with certification for 80 PLUS Gold efficiency, superior voltage regulation, Zero RPM mode for virtually silent operation, and 105°C All Japanese capacitors for better reliability.


CORSAIR Features


Zero RPM Fan Mode

The efficient design of the SF series means minimal excess heat generation, so the fan doesn't even need to spin under low to medium loads. And when you're pushing it hard, the thermal sensor controls the fan speed to ensure that it gets the cooling it needs without any extra noise.


Japanese 105°C Capacitors

Built with all Japanese 105°C capacitors to ensure solid power delivery and long term reliability.


Corsair 7 Year Warranty

Corsair SF Series power supplies are covered by Corsair's 7 year warranty which covers parts and labour.
