Corsair CX750 ATX 750 W power supply

The Corsair CX750 is a non-modular ATX unit rated at 750 W with 80 PLUS Bronze certification. It targets system builders who need dependable output for mid-range components without paying for fully modular cabling. A single 120 mm thermally controlled fan keeps noise low at typical loads. The compact 125 mm depth helps it fit most modern cases.

Installation notes and common issues

Fixed cables mean you must route every lead even if unused, so plan cable management before mounting the unit. The 24-pin ATX, 4+4-pin EPS and two 6+2-pin PCIe connectors cover standard motherboards and graphics cards. Builders sometimes forget the extra 6+2-pin branch on the second PCIe cable when powering dual-connector cards. SATA and legacy PATA leads are also permanently attached.

Pre-purchase checklist

Verify that your case accepts a 125 mm deep ATX supply and that the fixed cable lengths reach your motherboard and drive positions. Confirm the 100-240 V input range matches your mains supply. Ensure the single EPS connector is sufficient for your CPU power requirement. Check that two 6+2-pin PCIe plugs satisfy your graphics card needs before ordering.

Questions about this item

How can I confirm the CX750 is running correctly after installation?

The 120 mm fan spins up under heavy load and slows down at lighter loads, while the system remains stable at the rated 750 W output.

What comes in the box and which cables must I purchase separately?

The package includes the CX750 unit, a power cord, mounting screws and cable ties; all ATX 24-pin, EPS 8-pin, two PCI-E 8-pin, three SATA and two PATA cables are permanently attached, so no extra cables are required for a standard build.

Which version of this power supply should I choose for my build?

This CP-9020279-NA model is the single 750 W, 80 PLUS Bronze, non-modular ATX unit with a 125 mm depth; there are no other capacities or modular variants listed for this part number.
