Corsair SF1000 1000W 80 Plus Platinum Fully Modular ATX 3.1 SFX Power Supply

Product Description :

The Corsair SF1000 Platinum ATX 3.1 Fully Modular SFX SMPS is engineered for enthusiasts who demand extreme power in a compact footprint. Despite its small SFX form factor, this power supply delivers an impressive 1000 watts of Platinum-rated efficiency, making it ideal for high-end small form factor gaming PCs and professional systems.

Built to meet the latest ATX 3.1 standards, the SF1000 ensures superior reliability, power efficiency, and stability under demanding workloads. With full support for PCIe 5.1 and an included 12V-2×6 GPU cable, it is ready to power modern graphics cards such as NVIDIA GeForce RTX 40 Series GPUs with confidence.

To guarantee long-term durability, Corsair uses 100% industrial-grade Japanese capacitors rated at 105°C, ensuring consistent voltage delivery even during extended high-stress operation. The PSU is also rated for continuous operation at up to 50°C, making it dependable in thermally constrained SFF environments.

Cooling is handled by a 92mm PWM fan with fluid dynamic bearing, optimized for quiet performance. Corsair’s Zero RPM mode allows the fan to remain completely off at low to medium loads, delivering near-silent operation when your system is idle or under light use.

The fully modular Type-5 micro-fit connectors allow you to connect only the cables you need, reducing clutter and improving airflow inside compact cases. The flexible, space-saving cabling design makes cable management easier even in the tightest SFF builds.
