The Thermaltake ToughPower SFX 850W is a power supply unit designed for compact PC builds that require high, stable power delivery. It provides a total output of 850W and operates with 80 PLUS Gold certified efficiency, reaching up to 90% under load. This model is compliant with the ATX 3.0 standard and features a native PCIe 12+4pin connector, ensuring direct compatibility with PCIe Gen 5.0 graphics cards without the need for adapters. Its SFX form factor makes it suitable for small ITX and other space-constrained systems.
This unit features a fully modular cabling system, allowing builders to connect only the cables required for their specific components. This approach assists with cable management and can improve airflow within a chassis. Cooling is handled by a 92mm fan that operates with a noise level of up to 33.5 dB. A comprehensive set of power protection features is built-in, including over current, over power, over voltage, and short circuit protection to safeguard system components. The mean time between failures (MTBF) is rated at 100,000 hours.
