Im going to be running two GTX 780's in SLI with a Asus z87 Hero + Haswell 4670k. I will be overclocking all my components. I need help picking out the right PSU brand\wattage for my build.

Thanks!

Per the link below, it would appear that the two cards can use ~508 watts.
Unfortunately the article doesn't mention amps.

Nvidia specifies a minimum of 42 amps on the 12v rail for ONE 780, but I was unable to find any spec. for two. I would expect something around 70amps. WithOUT overclocking.
Since you plan on overclocking I would look in the 1000-1300Watt range.
Here are a couple I would recommend. I have posted the Newegg links but you might be able to find them cheaper elsewhere. Whatever you end up getting, get a reputable brand and model: Corsair, Seasonic, XFX, Antec, PC Power&Cooling.

(XFX is made by Seasonic)

Some may reply that this is overkill, you can use a smaller powersupply. That all depends on your overclock and how much headroom you want for doing such thing, and how hard you want your PSU to work. I always like more then I need, rather then just enough or to little.

Thanks for the reply! I was looking at the 1000w PSU's and hoped that i wouldnt have to spend anymore than that. Would I be able to get away with 1000w PSU from Seasonic?
