Hey all,
I am building a new system, and plan to put in 2 Palit GTX 460s (http://www.newegg.com/Product/Product.aspx?Item=N82E168...). My current PSU (no pun intended) is a 650W Antec Earthwatts, which is sturdy, but can only support one GTX 460 (has 1x6 pin and 1x6+2 pin; the GTX 460 is 2x6 pin), so obviously I need an upgrade (I'll need more power as well). I'm looking at 2 specific PSUs at the moment:
Corsair 1000W HX Series, 229.99 (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
Antec 1200W, 249.99 (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)

The Antec has more GPU connectors and more power, but the thing I'm stumped by is the rails. The Antec has 6 and the Corsair has 2. I don't know exactly what the number of rails means, so any advice or clarification would be greatly appreciated.

Other than that, feel free to ask questions and please vote!
Thanks!

A pair of 460's will need a little over 300w, what on earth are the rest of the components going to be to necessitate a 1kw PSU?

The number of rails are just different designs, don't worry too much about that, just take note of the maximum combined power for 12V as most of the time its its less than the sum of amps of the rails.

Honestly, you can power 2 GTX460s fine with that Antec, the GTX460s comes with one (or 2, depends on the model) Molex-> 6-pin adapters, just use that and youll be fine.

I guess I forgot to add that at some point later this year I want to add a 3rd 460, but I just checked and it's not 3-way SLI capable :( 

@Timop: I'll stick with my Antec until necessity dictates buying another PSU I guess. I really would like a modular PSU though.

@Hunter315: I like that price for what that PSU offers. Will definitely consider that.

If you really want a modular PSU with plenty of power for the "future" and relatively affordable, look at this: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

This is going to be my system (already purchased):
Core i7-930 + Titan Fenrir CPU cooler and about 7 case fans (non-LED)
EVGA FTW3 Motherboard (I feel like a douche whenever I have to write "FTW" as a product name...)
3x2GB Patriot Viper II Sector 7 DDR3-1600 RAM
SSD + HDD
GTX 460s in SLI for gaming and 3D; my old 9800GT will be for "lighter" use on second/third monitors
A few PCI cards here and there

It doesn't necessitate a 1kW, but some wiggle room would be nice. Plus, the Corsair is 1000W max power, and the Antec is 1200W continuous, so I feel safer buying a bigger PSU.

I've heard of Kingwin here and there, but never really knew much about them or their products. All I hear about concerning PSUs is Antec, Corsair, and Seasonic.
Found a review of that specific model, and it sounds great!
