Product Information

EFFICIENT POWER, RELIABLY DELIVERED
The CORSAIR VS550 delivers stable 80 PLUS efficiency power at an affordable price from the world’s most trusted name in PC power supplies.

Real power
The VS550 delivers a guaranteed 550 Watts of continuous power. With universal input the power supply includes circuitry with components that can tolerate a wide range of mains voltage support (100-240 VAC). Multiple power protection circuits provide for added peace of mind. A dedicated single +12V rail saves you from the hassle of balancing your components across multiple power cables.

Designed with builders in mind
Black cables, cable sleeving and connectors make it easy to build a great looking PC, while a super-compact 125mm deep housing fits in almost any modern PC case for maximum compatibility.

Low noise, high efficiency
The 120mm fan is thermally controlled, so it only spins up when needed, and is quiet even at full load. The VS550 is 80 PLUS rated for greater efficiency, so it generates less heat, and you’ll enjoy lower energy bills.

Reliability you can count on
The VS550 is backed with a comprehensive three-year warranty including legendary CORSAIR technical support and customer service.
