CORSAIR SF750 80+ Platinum ATX 3.1 Fully Modular Power Supply (750 W)

The Corsair SF750 is a small form factor (SFX) power supply engineered for compact, high-performance PC builds. Rated at 750 watts of continuous power output, it carries an 80 PLUS Platinum efficiency certification, meaning it operates with high efficiency across its load range — reducing heat and lowering electricity draw compared to lower-rated units. The SF750 is also formally certified for ATX 3.1 compliance, the latest ATX standard that places stricter requirements on transient load handling, making it well suited for modern graphics cards and high-core-count processors. A PCIe 5.1 12V-2×6 GPU cable is included, enabling compatibility with current and recent discrete graphics cards. The unit is fully modular using Corsair's Type 5 Micro-Fit connector system, so you attach only the cables your build requires — a significant advantage in tight SFX enclosures where cable clutter is the enemy of airflow and assembly. Cooling is handled by a 92mm fluid dynamic bearing fan. In Zero RPM mode, the fan remains stationary at low to medium loads, producing no fan noise whatsoever. Under heavier workloads the fan spins up as needed. Corsair rates the SF750 for continuous operation at up to 50°C ambient temperature, and the internal capacitors are Japanese electrolytic units rated to 105°C — both figures sourced directly from the product specification sheet. The unit achieves a Cybenetics Platinum efficiency rating and a Cybenetics A- noise rating, independently verified assessments that align with the 80 PLUS Platinum claim. Mean Time Between Failures (MTBF) is specified at 100,000 hours.
