CORSAIR SF1000L 1000W 80+ Gold Fully Modular SFX 3.1 Power Supply

The Corsair SF1000L delivers 1000 watts of continuous power in a compact SFX-L form factor, making it an ideal choice for small form factor builds that demand high-end performance without sacrificing space. Certified to the ATX 3.0 standard, it is engineered to handle the transient power requirements of the latest generation hardware, and ships with a PCIe 5.0 12VHPWR cable ready for NVIDIA GeForce RTX 40 Series graphics cards and similarly powered GPUs. Fully modular cable management is handled through Corsair Type 5 Gen 1 micro-fit connectors, letting you attach only the cables your system actually needs. This keeps your build tidy and promotes better airflow in cramped SFF enclosures. Thermal management is handled by a 120mm Fluid Dynamic Bearing (FDB) fan that operates in near-silence and supports Zero RPM mode, spinning down completely when system load is low for a virtually silent desktop experience. Corsair has specified 80 PLUS Gold certification with up to 90% efficiency at typical loads, alongside Cybenetics certification for lower noise and cooler operation under stress. Internal build quality centres on 100% Japanese primary electrolytic capacitors rated to 105°C, providing long-term stability under sustained loads. The unit is rated for full 1000W output at ambient temperatures up to 40°C, covering the vast majority of real-world operating conditions. Connectivity is generous for an SFX-L unit: one ATX connector, three EPS connectors, six PCIe connectors, 12 SATA connectors, and three PATA (Molex) connectors ensure compatibility with complex, multi-drive, multi-GPU configurations. Corsair rates the SF1000L for 100,000 hours MTBF and backs it with a 7-year warranty.
