I just ordered 2x gtx 460's for $130 after rebates and am in the process of ordering an i7 2600k.

I currently use this psu (Seasonic 600W)

Will it be sufficient? I have a spare Antec 750W earthwatts psu but I'm not familiar with 12v rails and such. I do plan on overclocking the CPU, the GPU's I will not however.

Edit

Here is the Antec PSU that I have. I would really like to avoid swapping it out as I like the seasonic PSU.

I think you'll want to switch to the Antec because the Seasonic is a bit underpowered for that setup, and isn't going to have the 4 x 6Pin PCI-Ex connectors that you'll need for your cards. The Antec OTOH is perfect for your setup.

^this.

Your Seasonic has only two 6-pin PCIe connectors but each GTX460 requires two, making your needing a total of four such connectors. If you desperately have to use this Seasonic, you may try to use adaptors to convert four 6-pin Molex to two new 6-pin PCIe connector. However, I do not suggest this.
And, the Antec has already two 6-pin and two (6+2) pin connectors, ready to be used without any adaptors.

BTW, welcome to OCN!
