Take a look through this thread and choose something from tier 1 or 2

Why 3x970's? If planning on 4k gaming I would avoid the 970 due to the recent ram issue with only 3.5gb usable

3.5gb is more than enough for 4k and maybe with a Ti coming up the .5gb issue will be fixed.

The G1 uses ~170w so 510w just for the 3 gpus. Unless you are running a 220w FX 9xxx, you could probably get away with an 850w Tier 1 unit. However I would personally one a little bigger for headroom and efficiency.

i would grab 2 980's if i were you, at 4k 2 980's would probably end up being better and more efficiant that 3x 970's due to scaling

I was looking for benchmarks and here's what I found. I would go with 2 980s.

The stuttering at 4k was probably due the the memory partition issues the 970 has when using more than 3.5Gb of vram.

I never said 4k and also this PSU is too future proof my build.
Im just going with 1 Gigabyte GTX 970 for 1080p@60fps.
If a game demands more or I get a better monitor I will buy more GTX 970 or sell
old GTX 970 for a 980 if necessary.

Just grab a 1000w psu then and be safe with plenty of extra room.
