Noob in need of PSU advice - GTX 460

[Leetsauce]

Hello everyone!

I'm in the process of a new build, and I'm trying to determine how much juice I'm going to need to run this thing.

I'm slightly familiar with wattage, but the "amps on the rail" is a completely new concept to me.

My budget is ~$80.

Here's my build:
i5-2500k
ASUS P8P67 R3 mobo
G.Skill Ripjaws 8GB DDR3
MSI N460GTX Hawk 1GB (eventually SLI)
WD Caviar Blue 500GB SATA HDD
Cooler Master Hyper 212+

In the future I hope to SLI the GTX 460, which means I'll probably need a lot of power.

Any and all suggestions would be appreciated!

Would any of these work just the same?

Fits in your budget and can handle a dual 460 SB rig pretty comfortably..

Oh that looks excellent with the rebate!

Would you recommend XFX over Corsair though?

Not really, they are all good units, but none of them have the 4 pcie connectors required for SLI 460's, the 2 I linked and the one Emperus linked to do.

Oh yeah I almost forgot about the 4 connectors.

I read on the specs that it says:
3 x 6+2 Pin PCI-E
1 x 6 Pin PCI-E

I'm guessing that I don't need the +2 pin at all, if they were all 6 pin they would work?

Too many people under estimate the importance of a strong, quality power supply. Choose one from Corsair, Antec TP, or Seasonic...
650watts will work for any single GPU system. (you need 550watts for a GTX 460)
850Watts will work for all but the highest end dual GPU systems. (about 700--750watts for a pair of 460's)

I'd go for a good solid 850. I you choose some thing like my favorite, Corsair HX850, it has a seven (7) year warranty, your like going to be Way past those 460's by then, so, I would NOT plan for "Just enough power...." and go with a smaller supply...

Dang man, 850w psu's are expensive these days.

I was able to find this antec though that I think should do the job.

Antec TruePower New TP-650 650W ($80)
http://www.newegg.com/Product/Product.aspx?Item=N82E16817371021

It's got 4 PCI-E connections and it has 2 +12v rails with 22A and 2 +12v rails with 25A.

Thoughts?
