I currently have a xfx core edition 850watt psu which has been rock solid for 3 years. I am upgrading to a gtx 1080 and will probably get another down the line. Will my current PSU be okay for gtx 1080 sli or should i purchase a new one i was thinking of getting the Corsair rm1000i 80+ gold Modular PSU is it a good one ?

Many thanks for your help

That PSU is heaps for 1080 SLI and very high quality, no need to go any higher, you can get a double OC and CPU OC on that without breaking a sweat.
