CORSAIR SF750 750W SFX PSU, 80 PLUS Platinum 🔌

This compact SFX power supply brings high-efficiency performance to small-form-factor PCs while freeing up interior space in larger cases. It is designed to deliver stable 750 W output with low acoustic levels, making it a practical choice for dense gaming rigs and workstation builds where noise and size matter.

Key Points

Corsair SF750 (2024) stands out by packing a large Platinum-rated efficiency into an SFX footprint, helping reduce heat and energy use under load. The unit is fully modular, which simplifies cable routing and keeps small cases tidy, and it includes an SFX-to-ATX bracket for flexible installation options. ⚙️

Cooling is managed by a 92 mm PWM fan with a fluid dynamic bearing, which offers quieter operation during typical desktop activity and ramps up as temperatures increase. The design is compliant with the ATX 3.1 standard and is prepared for PCIe Gen 5.1 power needs, so it copes with modern GPUs and transient power demands. 80 PLUS Platinum and ATX 3.1 are among the highlighted features from the manufacturer and the unit is described as PCIe 5.1 ready.

Benefits

Thanks to the Platinum efficiency rating, the supply tends to generate less waste heat and may help lower power bills according to the manufacturer. The fully modular cabling reduces clutter and improves airflow inside compact systems, which can lead to better component cooling in practice. For users sensitive to noise, the 92 mm fan and fluid dynamic bearing contribute to quieter daily operation, especially at moderate loads. 🛠️

Consider that very compact cases sometimes restrict airflow more than larger chassis. In such situations, positioning and case ventilation still play a major role in overall system temperatures. Also bear in mind that the high efficiency and ATX 3.1 compatibility are manufacturer specifications and real-world results depend on the rest of the build.
