I would get an 850W just to be safe, especially when your going with 2 GTX 670's

The xfx 750 is plenty capable of handling sli 670's The tx850 is also a good choice. They are both of excellent quality.

The TX850 Verison 2 is also made by Seasonic. Version 3 is made by CWT.

Difference is , if the PSU dies and it's still under warranty, Corsair have legendary customer support so he'll have an easier life sorting it out. XFX have given people a lot of trouble in the past

Stock you are looking at just over 500W for the system. OCing introduces a lot of uncertainty as voltages can be different for each part. 750W should cover it. 850W is fine if you want to go to excessive amounts.

I really doubt it matters whatsoever. Antec, Corsair, Seasonic and XFX all have good PSUs, and it's highly unlikely they'll fail even under a solid amount of stress. An 850W PSU will handle the system fine, and customer support probably won't even need to be involved.

Doesn't matter if they're " good " PSU's , the fact is that technology isn't perfect and can fail at one point in life. It's always to go with a brand with a better customer service, if they're all good PSU's then why choose the XFX over the Corsair which has better support?...Not really logical if you think about it.

@dylan1016 I can attest to that being a fantastic PSU with a great warranty and fan-less operation.
