Is this a good PSU for Dual 570 or 6970?

Corsair CMPSU-750TX 750W ATX12V v2.2
http://www.newegg.com/Product/Prod [...] 6817139006

Deep discount (always makes me leery) ends today.
I read somewhere that the TX model wasn't as good as HX, but didn't really say if TX was still plenty good or not.

Combined with 2500K OC to ~4.5ghz, 8GB DDR3 RAM, 2 HD, DVD RW. Gaming system

I want the PSU to last for a long time, 5+ years, so just dont want to cheap out and have to replace. But if its good, then good.

Thank you

Oh yeah, right now I have a case that houses PSU in the bottom, but may or may not replace with one that has PSU on top. Is this something I need to factor into PSU selection?

They both are quality but the 850W would be a bit more comfortable with dual 6970s for sure.

6970 CF, with no OC, will draw a max of 450W (less under normal gaming loads)
GTX 570 SLI, with no OC, will draw a max of 500W (less under normal gaming loads)

Add 200W for the balance of the system and at 750W you are just not quite running with a comfortable margin...

So, best to get a bit more power.

As to the TX line, it's generally quite good if you are on a budget. Yes, the HX line is better and the AX line is the best.

The XFX PSU linked is built by Seasonic, as is the 750TX V2... but it is the better unit
