What PSU would I need for this build?

Hardware Build a PC

I am currently in the process of finalizing my PC build and now all I need is a PSU. This is my current build now:

With that build what wattage PSU will I need? I was thinking around 600-700W but in the future I plan on getting a second GTX 670 and doing SLI and I plan on overclocking as well. And if anyone has any personal recommendations of a PSU they have or have had in the past that they really liked please leave a comment below. Thanks!

700w sounds about right for SLI + OC. Really, anything from Seasonic is good, but in general you'll want 80+ Bronze with a single 12v rail.

The Corsair CX750M seems like a solid choice, and it will fit in nice with that Corsair case and Corsair CPU cooler. ;)

I'm always a bit skeptic with PSUs. I have a similar build to what ure buying and im using a Corasir TX750. Jerm1027 is right, 700W will do the trick. However i wouldn't be so sure to SLI the 670 and OC the rig with only 700W. For that kind of use i'd go at least 800W

If you want to spend the money, I personally would go with a Corsair AX760i, but that's just my opinion.  Its plenty of power for what you intend on doing in your system.

Here is how much a GTX670 SLI system can pull: http://www.guru3d.com/articles_pages/geforce_gtx_670_2_and_3way_sli_review,4.html

That is 433w and that is with a OC i7-965 which is quite power hungry, a quality 550w will do the job if you want. Heck get a 650W just for good measure and there you go.
