Corsair SF750 80 PLUS Platinum Fully Modular 750W SFX Power Supply (Black)

The Corsair SF750 is a fully modular SFX power supply designed specifically for small form-factor PC builds where space is at a premium but performance cannot be compromised. Holding an 80 PLUS Platinum efficiency rating, the SF750 ensures that the majority of input power is converted into usable output — reducing waste heat inside already-tight SFF enclosures and keeping your system running cooler and quieter. ATX 3.1 certification is a standout feature of this unit. The ATX 3.1 standard sets demanding requirements around power reliability and transient response, and the SF750 is formally certified to meet them — not merely compatible. Bundled with the unit is a PCIe 5.1 12V-2x6 GPU cable, making it a plug-and-ready choice for modern discrete graphics cards including the NVIDIA GeForce RTX 40 Series. Cooling is handled by a 92 mm fluid dynamic bearing fan with Zero RPM mode. Under low to medium loads the fan stops entirely, delivering truly silent operation during everyday tasks. When loads increase, the fan spins up smoothly thanks to PWM control, maintaining thermal headroom without unnecessary noise. All cabling uses Type 5 Micro-Fit connectors and is fully modular, so you only attach the cables your build requires — a meaningful advantage when routing cables inside compact cases where every millimetre counts. Long-term reliability is supported by 100% Japanese-made 105 °C-rated electrolytic capacitors and a rated MTBF of 100,000 hours. The unit is also rated for continuous operation at 50 °C ambient, meaning performance does not derate under the elevated temperatures common in densely packed SFF chassis.
