I have a 6 year old system running an i7 920 with 6gbs of corsair dominator memory and recently upgraded my video card to a gtx 970 all on an evga x58 SLI motherboard. My previous psu was a 1000w turbocool that just gave out and I need to replace it. My question is what's a good one to get given my rig setup and one that might last a couple years? Not looking for top of the line but something that could get me a couple more years until I construct a new rig.
