newegg's calculator is a POS, pretty much. What do you expect from a website that's trying to make money from you, and that sells a lot of dishonestly-labeled power supplies?

Which power supply model is it? I think Thermaltake's had a few 80 plus bronze 750W models over the years. I don't recall that any were bad though, so any should be able to handle that system pretty decently. [edit: nevermind, TR2 RX has a 750W 80 plus bronze model that sucks] As long as you don't up the voltage on the GPUs a lot, you're good to go.

Since your question is fairly similar to a recent thread, I'll link you to the recommendations made there:

On second thought, the TR2 RX (TRX-750M) is pretty common and also pretty bad. Is that one called Black Widow?

http://www.hardwaresecrets.com/article/Thermaltake-TR2-RX-750-W-Power-Supply-Review/902/7

If it's that model you have, I'd rather have something else. A real 750W unit would be a good replacement.

So maybe if you could recommend a 750-850w psu

Fully modular would be cool..

You will be fine with a quality 750W with room to spare for overclocking. Stick with the HX750 or AX750.
