CORSAIR CX750M 750W 80+ Bronze ATX 3.1 Semi Modular Power Supply

The Corsair CX750M is a 750-watt semi-modular power supply built to the latest ATX 3.1 and PCIe 5.1 standards, making it a forward-compatible choice for modern desktop builds. Belonging to the CX-M Series, it carries the Cybenetics Bronze certification (also marketed as 80 Plus Bronze), delivering steady power output at up to 85% efficiency — which translates to lower electricity waste, reduced heat output, and quieter overall system operation. One of the headline features is the included native 12V-2x6 GPU power cable. This single cable delivers up to 600 W to the graphics card and incorporates a two-tone connector design that gives visual confirmation of a secure, fully-seated connection — an important safety cue when powering next-generation discrete GPUs that demand high transient power delivery. The internal design relies on a resonant LLC topology with DC-DC conversion, and the unit is populated with 105°C-rated industrial-grade capacitors. These components contribute to stable voltage regulation under sustained and transient loads, which is critical for system longevity and component safety. Cable management is simplified by the semi-modular layout: the ATX motherboard and CPU power cables are permanently attached (since every build requires them), while the remaining peripheral and GPU cables are fully removable. This approach reduces clutter inside the chassis without forcing builders to manage a full complement of modular connectors. A low-noise 120 mm fan with a custom fan curve keeps acoustics in check. Under light-to-moderate loads the fan operates at minimal speeds, and the compact 140 mm unit length ensures compatibility with a wide range of mid-tower and full-tower cases. Backing the purchase is a 7-year warranty from Corsair. — Verified Specifications — Model: CP-9020311-IN Series: CX-M Rated Output: 750 W Efficiency Certification: 80 Plus Bronze / Cybenetics Bronze ATX Standard: ATX 3.1 Connectivity: PCIe 5.1 ready Modularity: Semi-modular Fan: 120 mm (low-noise, custom curve) Unit Length: 140 mm PCIe 6+2 Connectors: 4 SATA Connectors: 8 Included GPU Cable: Native 12V-2x6 (up to 600 W) Capacitors: 105°C industrial-grade Warranty: 7 Years
