650 W ATX12V power supply for desktop builds

The Corsair CV650 delivers 650 W of continuous power through a single +12 V rail rated at 52 A. It fits standard ATX12V layouts and includes a 120 mm thermally controlled fan that runs quietly at low load. Non-modular cabling keeps the unit simple and affordable for mainstream system integrators.

80 PLUS Bronze efficiency and connector limits

Rated at up to 88 % efficiency, the unit meets 80 PLUS Bronze requirements across typical loads. It provides two 6+2-pin PCIe connectors, seven SATA power connectors, one 24-pin ATX connector, one 8-pin EPS connector, two peripheral connectors and one floppy connector. The fixed cable set cannot be reduced, so unused leads must be routed inside the case.

Check case depth and motherboard power needs

The power supply measures 125 mm in length, so verify that your chassis allows at least that much clear depth behind the mounting point. Confirm your motherboard uses a 24-pin main connector and an 8-pin EPS connector, both supplied. Ensure the two 6+2-pin PCIe leads match your graphics card requirements before ordering.

Questions about this item

Will the 125 mm length fit my case?

At 125 mm long it fits almost all modern ATX cases, but check your chassis clearance before ordering

Can it run a graphics card that needs two 8-pin connectors?
