500-600W will do. Just make sure it has at least an 80+ Bronze rating.

600W should be enough, as long you have a 80 plus bronze or higher psu then your okay.

A quality 450w can power your system, but I'll recommend a 550w unit for you. What is your budget and where are you able to buy from? Do you plan to SLI?

Some guy ran a 780ti off a 450w or something like that so he will be fine with 500w. Doesn't have to be 600w. 550 will do fine.

It might be recommended, but it by no means "has to be". I think it was tek syndicate that ran an overclocked 780ti (or something along those lines) on a 450w.

No you don't. The CPU and GPU will draw maybe a little over 300 watts combined on load.

 

OP can get away with something 450 watts and above to have overhead.

But Nvidia says you need a 600W PSU don't risk it.

If you have one system with a 780 and a 4770k in it, it is not going to draw more power than another system with the same specs. So if a 780 has been run off a 500w, then a 500w will be fine fir his 780. They set the bar high.

You're wrong, plain and simple.

It's not a risk. They just say alot extra if you have a bad PSU and a crazy, dual Xeon system

That recommendation is based on full system recommendation that take into consideration of various of components as well as various of PSU qualities. There are some 600w power supplies that like only have ~450w (37.5A) on the 12v rail for example, and that is as much as some quality 450w units such as the Seasonic G 450w.

 

If you know what you are doing, you certainly can go lower than what Nvidia recommends.

I have an overclocked i5 and two 770's running off of a 750 watt PSU.

 

By your logic, I should have a 1200watt PSU to power these things, which isn't true. I've ran these things at full load, overclocked and I'm still not maxing out the PSU.

 

Don't go off of what Nvidia and their partners put on the box, go off of what real world tests show, and real world tests show that the 780 coupled with a high performance CPU like the aforementioned 4690k will not pull more than 400 watts.
