CORSAIR CX750 80 Plus Bronze 750W Power Supply - Quiet, Reliable

In this review the CORSAIR CX750 is presented as a practical, no-frills ATX power supply for mainstream gaming PCs and system builders who want dependable continuous power without excess cost. The reviewer finds the unit delivers clean, steady output and operates quietly under typical loads, making it a solid choice for builds with a midrange CPU and a single video card. The three-year warranty and Corsair support add reassurance for buyers who prioritize long-term reliability over flashy modular cables or extreme overclocking headroom.

Key Features

• 80 PLUS Bronze certification: Up to 88% operational efficiency reduces waste heat and helps lower electricity bills under normal desktop loads.
• Full continuous power: The CX750 is guaranteed to deliver its rated 750 watts continuously, which helps maintain stability during long gaming or rendering sessions.
• Low-noise cooling: A thermally controlled 120mm fan spins down at lower loads for quiet operation and ramps up only when the supply is under heavier stress.
• Compact casing: The 125mm length fits easily into most modern PC cases, simplifying installation in tighter builds.
• Black sleeved cables and casing: Black sleeving and a powder-coated black case provide a clean, unobtrusive look that blends into most systems.

Who It's For

The CX750 suits mainstream gamers, creative hobbyists, and general-purpose system builders who need a reliable 750W supply without paying for fully modular cabling or top-tier efficiency. It is especially appropriate for builds using a midrange CPU and one video card where continuous wattage and quiet operation matter.

Power users chasing absolute efficiency, compact SFF builds requiring custom cables, or multi-GPU high-end systems may prefer a higher-efficiency or fully modular unit. Also, buyers who need a fully modular cable set for easy cable management should look elsewhere.

Pros & Cons

Pros

• Dependable continuous 750W output that keeps systems stable under sustained load.
• Quiet operation thanks to a thermally controlled 120mm fan that stays slow at lower loads.

• Compact 125mm length and black sleeved cables make installation and aesthetics straightforward.

Cons

• Not fully modular, so cable management is less tidy than with modular PSUs and some buyers report missing cables in specific builds.
