Cougar GR 850 850W 80 Plus Gold Power Supply
The Cougar GR 850 (model CGR GDN-850) is an 850W ATX 3.1 power supply with 80 PLUS Gold certification, active PFC and a 12V-2X6 connector for current graphics cards. Its +12V rail delivers up to 70.8A, and it is cooled by a 120mm rifle bearing fan.
It suits gaming and workstation builds with a powerful graphics card, where you want Gold efficiency and one connector set that covers both newer 12V-2X6 cards and cards that use 8-pin PCIe plugs. It also makes sense as an upgrade for an older system that is moving to a higher-wattage GPU.

- 850W total output, with up to 70.8A on the +12V rail

- ATX 3.1 with one 12V-2X6 (12+4) connector plus three PCI-E 8(6+2) connectors
