Replace 7 year old Corsair HX 620?

Seen that the SuperFlower Leadex GOLD 850W is just £90 shall I replace my 7 year old PSU? It's not faulty or anything although I do get coil whine from my GTX970 which some say could be the PSUs fauly.

Ultimately I want to go SLI 970s and game at 1440p (currently game at 1080p)

It seems too good a deal to miss. Don't think youll be sorry if u get it. I would.

Yeah that's what I've been thinking
