Description
The Thermaltake ToughPower GT 850W ATX 3.1 Standard Power Supply delivers reliable and efficient power for high-performance systems. With 80 PLUS Gold certification, it achieves up to 90% efficiency at typical loads, reducing energy waste and heat output. The fully modular design allows you to connect only the cables you need, simplifying cable management and improving airflow inside your chassis.
Equipped with a native 300W PCIe 5.1 connector, this PSU is ready for next-generation graphics cards, providing stable power delivery under heavy loads. The Smart Zero Fan feature ensures silent operation by keeping the fan off at low to medium loads, while the 12cm hydraulic bearing fan kicks in only when needed, balancing cooling and noise. Comprehensive protections (OVP, UVP, OCP, OPP, OTP, SCP) safeguard your components, and the 100,000-hour MTBF guarantees long-term reliability.
