650 W ATX power supply for desktop builds

The Corsair CX650 delivers 650 W of continuous power through a single 120 mm thermally controlled fan. It carries 80 PLUS Bronze certification for up to 88 percent efficiency at typical loads. The compact 125 mm casing fits most modern chassis and the black sleeved cables keep the interior tidy.

Included cables and mounting hardware

The box contains the power supply, a mains cord, mounting screws and cable ties for routing. Fixed cables provide one 24-pin ATX connector, one 8-pin EPS connector split as 4+4, two 8-pin PCIe connectors each split as 6+2, three SATA connectors on one lead and two PATA connectors on another. Cable lengths range from 400 mm to 500 mm with 100 mm spacing between plugs.

Compatibility checks before ordering

Verify that your case can accommodate a 125 mm deep ATX unit and that the 24-pin motherboard, 8-pin CPU and required PCIe connectors match your components. Confirm the mains input range of 100 to 240 V at 47 to 63 Hz suits your local supply. Ensure the +12 V rail capacity of 52 A covers the graphics card and CPU combined draw.
