The Corsair SF850 is a fully modular power supply unit designed for small form-factor (SFF) systems, delivering a total output of 850 watts. It is compliant with the ATX 3.1 and PCIe 5.1 standards, ensuring electrical compatibility with current-generation hardware, including modern GPUs. The unit operates with 80 PLUS Platinum certified efficiency, which corresponds to a typical efficiency of 92%, minimizing waste heat and reducing power consumption under load. Its compact SFX dimensions make it suitable for installation in space-constrained PC cases.
Cooling is managed by a 92mm pulse-width modulated (PWM) fan that utilizes a Zero RPM mode. This function keeps the fan inactive during low to medium loads to reduce operational noise. The fully modular design, paired with Type-5 Micro-Fit cables, allows for the connection of only necessary cables, which can simplify routing and improve airflow within compact enclosures. A suite of protection circuits, including over-voltage, under-voltage, and short-circuit protection, is integrated to safeguard system components.
