Manufacturer description
The CORSAIR CX750 is a non-modular ATX power supply that delivers 750 watts of continuous power, which is enough headroom for a mid-range gaming build pairing a modern six- or eight-core CPU with a single graphics card. Its 80 PLUS Bronze certification means up to 88 percent operational efficiency, so less of the wattage you pull from the wall is wasted as heat and more of it reaches your components. CORSAIR rates the CX Series to deliver its full rated wattage continuously rather than as a peak burst figure, so the 750W number on the box is the number you can actually plan a build around…
SpecPicks Verdict
SpecPicks scored CORSAIR CX750 80 Plus Bronze Non Modular Low-Noise ATX 750 Watt… using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category.

Frequently Asked Questions
Is 750W enough for my gaming PC?
750W of continuous power generally covers a mainstream gaming build with one graphics card and a modern desktop CPU. Add up your specific GPU and CPU power ratings and compare them against the 750W rating before you buy.
Is the CORSAIR CX750 modular?
No. This is the non-modular version, so all cables are permanently attached to the unit. You will need to route and tuck away any connectors your build does not use.
How loud is the fan?
It uses a 120mm thermally controlled low-noise fan that only spins at high speed when the supply is under heavy stress, slowing down for quieter operation at lower loads.
Will it fit in my case?
The casing is 125mm long, a compact depth that CORSAIR says fits almost all modern PC cases. Check your case's PSU clearance spec if you are working in a small-form-factor chassis.
What does 80 PLUS Bronze actually mean here?
It certifies the unit reaches up to 88% operational efficiency, meaning less of the power drawn from the wall is lost as heat, which lowers energy costs and reduces heat inside the case.
