Corsair 750W PSU

I don't think Corsair is renown for their Power supplies, only RAM. Careful. Look at Antec, OCZ, and PCP & Cooling PSUs, brands with good PSU reputation.
 
LOL really because I was read on another forum that Corsair, Antec, OCZ, and PCP were the best brands going in the PSU department.

What would you recommmend for a 750w PSU. Or is 750w to much or to little. Here is my planned setup:

Asus Maximus Formula
Q6600
4 GB of Ram, not sure what brand
Lite-on DVD writer
Zalman 9700
2x Seagate 7,200RPM 250GB in RAID 0
Crossfire 3870's
Card Reader
Three 120mm fans and 2 90mm fans


I would like some room for upgrades later down the road.

Thanks

Antec Quattro 850W

Thermaltake Toughpower 850W

OCZ GameXStream 850W

I understand 750W+ is alot for my system I believe but I would like room for upgrades in the future. Also if non of these picks, what other one. And if it is SLI ready will that still work in Crossfire.
 
Go with the corsair they are one of the best in the PSU industry. Another possibility would be the PC Power and Cooling(Something Like That) 750 qaud.
 
I use the Corsair HX620W, and can only say I'm very pleased with it. (I read good reviews about it, and they gave a 5 year warranty on it, I mean, 5 years is a lot for a powersupply's warranty :) ) I don't know the TX series tough.
