Looking for advice on PSU for building a Gaming Rig.


I'm looking for advice on a Gaming/ productivity build. I don't upgrade often but I usually hope that it lasts about 3-5 years but obviously sometimes that is not the case.
Anyhows I have nailed down the following parts but I can't seem to figure out the PSU, I want to have the option of an SLI system but i'm confused as to what the PSU power output should be, would 1000w be excessive or just about right for future proof?

Here are the following component, still need to decide on RAM or whether to go for Intel 4th Gen processor 4770K:

CPU Cooling Fan:- Noctua - Heatsink + Fan CPU Cooling Kit - Dual Fan - NH-D14.
CPU:- Intel 3rd Generation Core i7-3770K CPU.
SSD:- Crucial M500 960GB 2.5 inch SATA Solid State Drive.
Case:- Zalman MS800 Plus Midi Tower PC Case

I assume the parts I have currently selected are all compatible with each other and are good enough for a while, I haven't built a PC a few years but I am really looking forward to it.
Thank you very much for any advice given.

  1. what GPU do you have or will you be getting? What GPU(s) you will use will be the bulk of your power needs.
  2. My personal advice is to go for anything 850+ watt with a good efficiency rating like 80+ Gold certified with a good warrenty.

    I'm like you I went for future proof (as close as I could go) and I had an unlimited budget so I purchased Cooler Masters 1300 watt Silent Pro Hybrid.
  3. Yeah it seems the best way, as long as it hits about 3-5 years like my previous build, I'll be happy.

    I haven't quite decided what GPU, I haven't done SLI before so I was seriously thinking about that route, as I usually go for a one GPU solution.
    I was thinking two GeForce GTX 770 or is that overkill?
  4. depends on your needs/wants, but whatever you decide, here is a reference you can use:
