The Corsair CX750M (model CP-9020222-NA) is a 750-watt ATX power supply for desktop PCs. It belongs to Corsair's CX-M series, which pairs 80 PLUS Bronze efficiency with semi-modular cabling and low-noise operation. It suits new builds and upgrades where a tidy case and a quiet fan matter.
What 750W means
The wattage is the maximum continuous power the unit can supply to the whole computer. Parts draw only what they need, so a 750W supply typically leaves headroom for a mid-range to fairly capable system. Check the recommended supply size from your graphics card maker.
Semi-modular cabling
On a semi-modular unit, the essential cables (usually the main motherboard cable) are attached, while the others plug in as needed. Corsair says this lets you connect only the cables you need for a clean build with easy cable management. The unit has dual EPS12V connectors for the processor, and Corsair lists two or four PCIe 8-pin connectors, which it says covers today's demanding PC upgrades.
80 PLUS Bronze
80 PLUS Bronze is a baseline efficiency certification. Bronze typically means about 82% efficiency or higher at common loads, so the supply wastes less power as heat than an uncertified one. Higher tiers such as Gold are more efficient still. Corsair says Bronze means more efficient power use and lower temperatures in use.
Quiet fan and capacitors
Corsair says the fan uses a rifle bearing, which it describes as lasting longer than conventional bearings with less noise. It lists Japanese capacitors rated up to 105°C for consistent, reliable power, and DC-DC conversion for the +3.3V and +5V rails to provide clean, consistent power to components and peripherals. DC-DC conversion typically helps keep those voltages stable when the load changes.
Size and warranty
The listing gives dimensions of 5.5 x 5.9 x 3.4 inches and a weight of 3.3 lb (about 1.5 kg). Check the unit's length in the manual against your case. Corsair lists a five-year warranty.
Who it suits
It suits builders who want a quiet, tidy ATX supply for a general-purpose, gaming or home-office PC and who don't need fully modular cables or the highest efficiency tier.
What to check before you buy
- Power needs: compare 750W with what your processor and graphics card recommend.
- Connectors: make sure the cables supplied match your parts.
- Fit: confirm the ATX form factor and the space in your case.
- Newer cards: the listing doesn't mention the newer 12-pin graphics card connector, so check whether your card needs one.
- Installation: follow the manual and local electrical codes, power down and unplug the system before working inside, and use a suitable outlet.
The short version
- A 750W ATX power supply, semi-modular, with dual EPS12V cables.
- 80 PLUS Bronze efficiency and a low-noise rifle bearing fan.
- Japanese capacitors rated to 105°C and DC-DC conversion for +3.3V and +5V.
- Five-year warranty.
