CORSAIR SF1000 80+ Platinum Fully Modular ATX 3.1 SFX Power Supply (1000W)

The CORSAIR SF1000 is a 1000-watt SFX-form-factor power supply built for enthusiast-grade small form factor (SFF) and compact ATX builds. Carrying an 80 PLUS Platinum efficiency certification, it delivers high conversion efficiency that keeps operating temperatures low and electricity bills in check — important in thermally constrained cases where every watt of waste heat matters. One of the SF1000's defining features is its ATX 3.1 compliance, a formally certified standard (not merely a claim) that mandates tighter voltage regulation and transient load handling. Paired with an included PCIe 5.1 12V-2x6 GPU cable, it is ready to power current-generation discrete graphics cards, including NVIDIA GeForce RTX 40 Series models, without adapters or workarounds. Cabling is fully modular via Type-5 Micro-Fit PSU connectors, meaning only the cables your system actually needs are connected. This is especially valuable in compact enclosures where unused cable bundles can obstruct airflow and complicate builds. Four PCIe 6+2 connectors and four SATA connectors provide ample connectivity for multi-GPU storage-rich configurations within the SFX footprint. Cooling is handled by a 92 mm fluid dynamic bearing PWM fan that adjusts speed in response to thermal load. At low to medium loads, Zero RPM mode disables the fan entirely, producing a completely silent operating environment. The unit is built using 100% Japanese electrolytic capacitors rated to 105°C, supporting reliable operation up to a continuous ambient temperature of 50°C — a specification that matters in thermally challenged SFF chassis. A seven-year warranty covers the SF1000, reflecting the manufacturer's confidence in component longevity.
