Thermaltake ToughPower GF1 TTP-850AH3FCG Power Supply - Internal - 120 V AC, 230 V AC Input - 3.3 V DC @ 22 A, 5 V DC @ 22 A, 12 V DC @ 70.9 A, 12 V DC @ 300 mA, 5 V DC @ 3 A Output - 850 W - 1 +12V Rails - 1 Fan(s) - 90% Efficiency

High amperage single +12V rail. Powerful single +12V rail ensures a stable and reliable supply to other PC components. Extremely strict voltage regulation <±2%. The voltage regulation, more strict than Intels standard ±5% for major rails and ±10% for -12V, is set to no more than ±2% for major rails to meet the highest performance. Zero cable platform. Farewell to messy cables! Thermaltake has connected the back panel and the PCB with a copper plate for better heat dissipation and impressive output power quality. Premium Japanese 105 deg.C/221 deg.F capacitors. Providing great durability as well as offering the highest stability, while remaining reliable. Ultraquiet 140mm hydraulic bearing fan. Featuring a 140mm hydraulic bearing fan with intelligent RPM controls to help guarantee superior cooling performance and near silent operation. Fully modular low-profile flat cable. Offers cable selection for users while powering the system at an advantageous voltage. Low-profile flat cable makes cable management easier, reduces clutter and increases airflow inside the chassis. Energy efficient - designed to use less energy than alternative products, potentially helping you save money and reduce your carbon footprint.
