Corsair SF750 at a Glance
Introduction
The Corsair SF750 750W 80 PLUS Platinum SFX Power Supply (CP-9020284-IN) is built for small-form-factor gaming PCs, compact workstations and space-conscious enthusiast systems. Its 750W continuous output provides substantial power capacity in a compact SFX enclosure.
With ATX 3.1 compliance and PCIe 5.1 compatibility, the SF750 includes a native 12V-2x6 GPU power cable for compatible modern graphics cards. Its 80 PLUS Platinum certification indicates high power-conversion efficiency, while Cybenetics testing provides additional efficiency and noise ratings.
The fully modular Type-5 Micro-Fit cable system lets builders connect only the cables needed for their configuration. This helps reduce cable clutter and makes routing easier in compact cases where space is limited.
A 92mm PWM fan with Zero RPM mode helps balance cooling and acoustics, and the included SFX-to-ATX mounting bracket allows installation in compatible cases designed for standard ATX power supplies.
Key Features
750W Continuous Power
Delivers 750W of rated continuous power through a single +12V rail rated at 62.5A, supporting compatible high-performance CPUs and graphics cards within the PSU's capacity.
80 PLUS Platinum Efficiency
Platinum-rated conversion efficiency helps minimise wasted energy and heat. The model also carries Cybenetics Platinum efficiency certification.
Native 12V-2x6 GPU Cable
Includes a native 12+4-pin GPU cable rated for up to 600W for compatible graphics cards, simplifying the power connection compared with multi-plug adapter arrangements.
ATX 3.1 and PCIe 5.1
Designed to meet the ATX 3.1 power-supply standard and support PCIe 5.1-compatible graphics power connections in modern compact systems.
92mm PWM Fan and Zero RPM
The fan adjusts its speed according to cooling requirements. Zero RPM mode stops the fan at sufficiently light loads for silent PSU operation when conditions permit.
Premium Compact Design
Features 105°C-rated Japanese electrolytic capacitors, fully modular Type-5 Micro-Fit connections and an SFX-to-ATX mounting bracket for broader case compatibility.
Power Delivery and Cooling Technology
The SF750 uses a single +12V rail rated at 62.5A, providing the full 750W output for compatible system power demands. This gives compact gaming and workstation builds a substantial power budget without requiring a full-size ATX PSU.
ATX 3.1 compliance and PCIe 5.1 compatibility support modern graphics-card power requirements. The included native 12V-2x6 cable is rated for up to 600W, but the graphics card's own power requirements and the overall system configuration must remain within the PSU's 750W capacity.
The 92mm PWM fan adjusts cooling according to thermal demand. Zero RPM mode can stop the fan at low loads, while the fan resumes when additional airflow is needed.
Its fully modular Type-5 Micro-Fit cables are designed to help save space in small-form-factor builds. Use only cables explicitly compatible with this PSU; modular cable pinouts can differ between models and series.
Technical Specifications
Dimensions are listed as length × width × height. Connector totals represent the listed connectors, not necessarily separate cables. Verify the included cable set for the exact regional package before purchase.
Ideal Use Cases
Small-Form-Factor Gaming
Designed for compact gaming systems that need substantial power without the footprint of a full-size ATX PSU.
Compact Workstations
Suitable for compatible small workstations used for productivity, development and content creation workloads.
Modern GPU Builds
The native 12V-2x6 connection supports compatible modern graphics cards, subject to their power requirements and total system demand.
Clean Custom PC Builds
Fully modular Type-5 cables allow builders to connect only what is needed, improving cable management in space-constrained cases.
Before You Build
- Confirm that your case supports the SFX form factor. The included SFX-to-ATX bracket can help install the PSU in compatible ATX PSU mounts.
- Check the graphics card's recommended PSU wattage, peak power needs and connector requirements before purchase.
- The included 12V-2x6 cable is rated for up to 600W, but the PSU's overall continuous output remains 750W. The complete system must stay within its power budget.
- Use only the modular cables supplied with this model or cables explicitly confirmed as compatible with the exact SF750 revision. Never assume cables from other Corsair PSU families are interchangeable.
- Allow sufficient room for cable bends, airflow and access to connectors in compact cases, particularly when installing a high-power graphics card.
Frequently Asked Questions
1. Is the Corsair SF750 a 750W power supply?
Yes. The Corsair SF750 (CP-9020284-IN) is rated for 750W of continuous output, with a single +12V rail rated at 62.5A.
2. Is the Corsair SF750 fully modular?
Yes. All PSU cables are detachable, so you can connect only the cables required by your system. Its Type-5 Micro-Fit cabling is designed to help simplify cable management in compact cases.
3. Does the SF750 support ATX 3.1 and PCIe 5.1?
Yes. This version is ATX 3.1 compliant and supports PCIe 5.1-compatible GPU power connections.
4. Does it include a native 12V-2x6 GPU cable?
Yes. The listed package includes a native 12+4-pin 12V-2x6 GPU cable rated for up to 600W for compatible graphics cards.
5. What does 80 PLUS Platinum mean?
It is an efficiency certification indicating that the PSU meets defined power-conversion efficiency requirements under specified test conditions. The SF750 also carries Cybenetics Platinum efficiency certification.
6. What is Zero RPM mode?
Zero RPM mode allows the PSU's cooling fan to stop under sufficiently light loads when additional airflow is not required. The fan resumes operation as cooling demand increases.
7. Can the SF750 be installed in an ATX case?
It can be installed in a compatible case with an appropriate SFX-to-ATX mounting arrangement. The included bracket is intended to support installation in larger PSU mounts, but case clearance should still be checked.
8. What warranty does the Corsair SF750 include?
Corsair SF750 listings specify a seven-year manufacturer warranty, subject to the applicable warranty terms and conditions.
