Corsair VS550 550W power supply

The Corsair VS550 is a 550W ATX power supply built to the ATX12V v2.31 and EPS 2.92 standards. It carries 80 PLUS White certification and uses a single +12V rail rated at 44A. A thermally controlled 120mm sleeve-bearing fan manages airflow. The unit measures 125mm in length and includes over-voltage protection.

Entry-level desktop builds and office upgrades

This unit suits standard desktop PCs and basic workstations that need reliable 550W delivery with 80 PLUS White efficiency. It provides two 6+2-pin PCIe connectors for mid-range graphics cards and six SATA connectors for drives. Systems requiring higher efficiency ratings, fully modular cabling or greater +12V current should consider other models.

ATX case integration with fixed cabling

The 125mm depth fits most ATX cases and leaves room for cable routing behind the motherboard tray. Fixed cables include a 24-pin ATX connector, an EPS12V/ATX12V connector, two PCIe connectors, six SATA connectors and a combined SATA-PATA-FDD lead. Active PFC accepts 100-240V input at 47-63Hz without manual switching.
