Introduction
The Corsair SF1000 is a 1000W fully modular power supply from the Corsair SF Series, built for small-form-factor gaming PCs and space-conscious high-performance desktop systems. Its SFX form factor combines substantial power capacity with a compact footprint, making it an option for compatible Mini-ITX and other small PC builds.
The unit carries 80 PLUS Platinum and Cybenetics Platinum efficiency certifications and is formally certified for Intel ATX 3.1 compliance. It includes a PCIe 5.1 12V-2x6 GPU power cable, Type-5 Micro-Fit modular connections and a 92mm PWM fluid dynamic bearing fan with Zero RPM mode.
With 105°C-rated Japanese electrolytic capacitors and a specified continuous operating temperature of 50°C, the SF1000 is designed for demanding compact systems. The manufacturer-listed warranty is 7 years. Model: CP-9020257-IN.
Features
1000W Continuous Output
Provides up to 1000W of continuous rated power, including up to 1000W on the +12V rail, for compatible performance-oriented builds.
80 PLUS Platinum Efficiency
Platinum certification indicates efficient AC-to-DC power conversion under the applicable certification test conditions.
ATX 3.1 and PCIe 5.1
Formally certified for ATX 3.1 compliance and supplied with a dedicated 12V-2x6 GPU power cable for compatible modern graphics cards.
Compact SFX Form Factor
The SFX design makes this PSU suitable for compatible small-form-factor cases where internal space is limited.
92mm PWM Fan with Zero RPM
The fluid dynamic bearing fan provides active cooling when required, while Zero RPM mode can stop the fan at low to medium loads.
105°C-Rated Japanese Capacitors
Uses 100% industrial-grade Japanese electrolytic capacitors rated for 105°C, alongside a manufacturer-specified 50°C continuous operating temperature.
Technology and Design
SFX Power in a Compact Chassis
The SFX form factor is designed for compact systems where a conventional ATX PSU may not fit. Check the case manufacturer's PSU compatibility requirements and available cable space before installation.
ATX 3.1 and PCIe 5.1 Connectivity
The SF1000 is formally ATX 3.1 certified and includes one PCIe 5.1 12V-2x6 GPU power cable. Verify the exact connector and wattage requirements of your graphics card before use.
Type-5 Micro-Fit Modular Cabling
Fully modular Type-5 Micro-Fit connections allow builders to attach only the required cables. Their compact design helps reduce cable congestion in smaller PC enclosures. Type-5 cables are not universally interchangeable with other Corsair cable types.
Quiet Cooling and Platinum Efficiency
A 92mm PWM fluid dynamic bearing fan supports temperature management, while Zero RPM mode can eliminate PSU fan noise at low to medium loads. Platinum efficiency certification supports power-conscious compact PC designs.
Technical Specifications
Recommended Use Cases
Small-Form-Factor Gaming PCs
Ideal for compatible compact gaming builds that need high power output without a full-size ATX PSU.
Mini-ITX Builds
A suitable option for Mini-ITX systems housed in cases specifically designed to support SFX power supplies.
Compact High-Performance PCs
1000W output can support demanding compatible configurations when component power requirements and cooling are properly planned.
Space-Conscious Builds
The compact chassis and modular Type-5 cabling help builders manage limited internal space.
Before You Build
- Check that your case supports the SFX form factor and allows sufficient room for modular cables.
- Verify total CPU, GPU, storage and peripheral power requirements before selecting a 1000W PSU.
- Confirm the graphics card's power connector requirements and use the included 12V-2x6 cable only as instructed by the GPU manufacturer.
- Fully insert GPU power connectors and follow the graphics card manufacturer's cable-clearance and bending guidance.
- Use only Corsair Type-5 cables explicitly approved for this exact PSU. Modular cables from other models may not be electrically compatible.
- Check the motherboard's CPU EPS connector requirements and the number of PCIe connectors required by your graphics card.
- Review the supplied cable inventory before finalising a build with numerous SATA drives or peripheral accessories.
- Confirm the warranty terms and supplied regional power cord for SKU CP-9020257-IN before purchase.
