Help with finding the right PS.

[SiC420]

I currently have a 750W Corsair power supply, but just purchased two GTX 680's. I'm wanting to buy a new power supply as I plan on upgrading the rest of my computer and want to attempt over clocking, and I'm pretty sure that my current PS won't be able to handle the new cards. Below are my current spec:

Intel i5-750
4GB RAM
5 Internal HDDs
3 DVD drives

I'm looking for a good power supply that has enough power for over clocking and what not. The only thing I would like is for it to be modular, but isn't a must.

Any recommendations on what I should get? Thanks in advance for all of your help!

A 750W corsair will handle GTX 680 SLI.

http://www.guru3d.com/article/geforce-gtx-680-sli-review/4
-> system load 473W from the wall, CPU = i7-965 @ 3.75
-> 473 * 0.85 = 400W power consumption (adjusted for efficiency)

http://www.hardocp.com/article/2012/03/28/nvidia_kepler_geforce_gtx_680_sli_video_card_review/8
-> 549W in the most power consuming game, from the wall. CPU = i7-2600K @ 4.8GHz

http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_680_SLI/21.html
-> 360W calculated peak power consumption of the graphics cards only in Crysis 2 (add CPU + rest of system)

What resolution do you game at? I doubt you'll benefit much from overclocking 680 SLI, it's already so powerful. Better to keep the OC as a mild one for lower noise and heat output.

I wasn't really planning on overclocking the GPU's, I was thinking about overclocking my CPU (my current one and my new one that I'll be getting down the road).

That's the current PSU I'm currently running, do you really think it will be enough to handle all of this and a CPU overclock?

Thanks for your help, I'm a noob when it comes to PSU's.

You'll be fine even with both a cpu and gpu overclock. More than fine with just a cpu overclock.

Well, that's good news! I thought for sure I'd have to upgrade my PSU.

Thanks for the help, everyone!
