Corsair CX Series 750W Power Supply 80+ Bronze - Renewed

The Corsair CX Series 750W power supply is built around an LLC resonant converter topology paired with DC-to-DC secondary regulation — a design approach that delivers tighter voltage regulation and improved efficiency, particularly at low to moderate loads where most PCs spend the majority of their time. With 80 Plus Bronze certification, the CX750 converts at least 82% of AC power into usable DC power at typical loads, meaning less electricity is wasted as heat and your energy bills stay lower compared to a generic, uncertified unit.

Cooling is handled by a single thermally controlled 140mm fan that scales its speed to match internal temperatures, keeping noise levels low during everyday tasks and light gaming. The non-modular cable design keeps the price down, though it does mean you'll need to bundle and tuck unused cables out of the way. All cables feature black sleeving that matches the black housing, giving the unit a cohesive look inside a windowed case. As a renewed product, this CX750 has been tested and verified to meet original performance specifications, making it a practical choice for builders who want Corsair reliability without paying full retail price.
