Hello there!

I've decided to build my first system about week or two ago. Spend a lot of time researching about hardware and etc. Yet there is still couple points I am not sure about and don't want to proceed with out very clear understanding. I am on a budget, max 650$ excluding monitor.

Here is my potential parts for a system:
NZXT Gamma
Intel Core i5-2500
EVGA GTX 460 SuperClocked
4gb Corsair DDR3 1333mhz
500gb 7200rpm HD
PSU about 600-650W ?

So my question regarding PSUs is how do I choose it apart from the watts. I want to buy a EVGA GeForce GTX460 SuperClocked GPU and it seem to need a minimum of 450W. As I understand I need a ~38 amps on 12v rails. Yet I can't really find a psu that would have 38+ amps on each rail. I am probably misunderstanding somewhere. Sure there is PSU with equal and higher parameters, but I can't spend too much on it yet. In the future PSU is the first thing to upgrade for me. Still can low cost PSU(40-50$) handle and not damage my system for about a year of usage?
Here is some of the psus I've found:
http://www.amazon.com/Diablotek-650-Watt-Power-Supply-P...
+12V1@23A
+12V2@23A
Could find specs for these two, which probably(?) eliminates them:
This one seems to be a bad choice for my case, because of short wires. But the low price keeps me from deleting this link http://www.amazon.com/Blue-Star-4-pin-Supplies-PCI-Expr...

P.S. 600-650W too much? o.O
Links to possible choices and any constructive criticism is welcome.

the diablotek is crap. so is the blue star. the third link doesnt work, but if its inexpenisve its porobably crap too...stick to a good brand like corsair, seasonic, or antec.
this is a good psu for a good price.

the antec ea500 is also a good choice. if you want to go for the cheapest, go for the antec basiq power bp500.but i recommend the corsair.

A quality 500W unit would be fine.
I understand you're on a budget but i don't advise skimping on probably the most important component in your rig.

great!
Yet would you recommend me buy this bundle? To get this cheap deal I need to buy it now. But there is no mobos for new generation i cores. So the case w/ psu will just sit in my closet for a month. And there is no way for me to test if it works fine. Same is with gpu, I found a good one for 185$ and -40$MIR (need to buy soon for MIR). Again I won't be able to test it. On other hand I don't want to miss a good deal and regret later.
At some point I was thinking of maybe buying phenom II core. But from reading forum it just don't stand a chance with any i cores.
