CORSAIR CX SERIES POWER SUPPLY
Corsair CX750 750W 80 PLUS Bronze Power Supply
Dependable 750W continuous power, Bronze-rated efficiency and thermally controlled cooling in a compact ATX design for compatible gaming and productivity PCs.
Corsair CX750 at a Glance
Introduction
The Corsair CX750 750W 80 PLUS Bronze Power Supply (CP-9020279-IN) is designed for desktop users who need reliable power delivery for gaming, productivity and everyday computing. Its 750W continuous output provides additional capacity compared with lower-wattage models for compatible systems with more demanding components.
The 80 PLUS Bronze certification indicates power-conversion efficiency of up to 88% under specified conditions. A thermally controlled 120mm fan adjusts its speed according to cooling requirements, helping reduce fan noise during lighter workloads.
The 125mm-long chassis supports installation in many modern ATX-compatible cases. Its non-modular design keeps the cabling permanently attached, so unused cables need to be managed inside the cabinet.
Key Features
750W Continuous Power
Provides 750W of rated continuous output, with up to 744W available on the +12V rail for compatible processor and graphics-card power requirements.
80 PLUS Bronze Efficiency
Bronze-rated power conversion with advertised efficiency of up to 88% helps reduce energy lost as heat under suitable operating conditions.
Thermally Controlled Fan
The 120mm sleeve-bearing fan varies its speed according to thermal demand, balancing airflow with noise during everyday use.
Compact 125mm Chassis
The short PSU body helps simplify installation in many cases and leaves more room for cable routing where the cabinet layout permits.
Essential Power Connectors
Includes a 24-pin motherboard cable, a 4+4-pin CPU power cable, three PCIe 6+2-pin connectors, three SATA connectors and two 4-pin peripheral connectors.
Five-Year Warranty
Corsair specifies a five-year manufacturer warranty for the CX750, subject to the applicable warranty terms and conditions.
Power Delivery and Cooling Technology
The CX750 uses an ATX12V v2.31 design with a single +12V rail rated at 62A, equivalent to 744W. This rail supplies the primary power demands of the processor and graphics card, within the PSU's overall capacity and the system's requirements.
Its thermally controlled 120mm fan adjusts its speed as cooling demand changes. Under lighter workloads, it can run more slowly for quieter operation, while heavier loads require increased airflow.
The 80 PLUS Bronze rating describes power-conversion efficiency under defined test conditions. Actual efficiency varies with system load and input conditions, so the certification does not guarantee a fixed reduction in electricity costs.
Technical Specifications
Specifications are based on Corsair's product documentation and matching Indian listings. Confirm graphics-card connector requirements and system power demand before purchase.
Ideal Use Cases
Mainstream Gaming PCs
A potential match for compatible gaming systems whose CPU, GPU and total power requirements fit within a 750W supply's capabilities.
Productivity Workstations
Suitable for compatible desktop systems used for office work, development, content creation and other demanding workloads.
Home and Office PCs
Provides continuous power for desktop systems with multiple storage devices and peripherals, provided the complete configuration is compatible.
Compact ATX Builds
The 125mm chassis length helps with installation in many compatible cases where PSU clearance and cable routing are important.
Before You Build
- Check the recommended PSU wattage for your exact processor and graphics card before buying.
- The CX750 is non-modular, so its cables cannot be detached. Plan cable management around the available space in your cabinet.
- Corsair lists three PCIe 6+2-pin connectors across two PCIe cables: one cable with a single connector and another with two connectors.
- This model does not list a native 12V-2x6 GPU power connector. For a graphics card requiring a 16-pin connection, verify the manufacturer's approved connection method and adapter requirements.
- For high-power graphics cards, heavy overclocking or future upgrades, consider a PSU with the required native connectors, suitable power capacity and appropriate ATX specification.
Frequently Asked Questions
1. Is the Corsair CX750 a 750W power supply?
Yes. The Corsair CX750 (CP-9020279-IN) is rated for 750W of continuous output, with up to 744W available on its +12V rail.
2. What does 80 PLUS Bronze mean?
It is a power-efficiency certification indicating that the PSU meets defined conversion-efficiency requirements under specified test conditions. Corsair advertises efficiency of up to 88% for this model.
3. Is the Corsair CX750 modular?
No. It is a non-modular PSU, meaning its cables are permanently attached. Any unused cables must be managed inside the case.
4. How many PCIe power connectors are included?
