PSU recommendations?

I just spent about an hour at newegg looking at power supplies, and I had a heck of a time trying to find one with dual 12v rails with over 18a per rail. I found one that had 20a per rail, and one with 22a per rail. I could barely find any with over 30a on a single 12v rail. I'm looking for a PSU about 500w or more, with dual rails, and at least 25a per rail. Oh, and it should be under $100. I don't really NEED it, I'm just kind of looking. I'm currently running a 450w with dual 12v rails; 15a on each rail. I haven't had any problems, ever. I just upgraded to a Radeon x1950GT 256mb AGP card, and it has two molex power connectors, and I just want to be sure that I have ample juice. I have one SATA2 HD, 1.5gb DDR400, 2 DVD drives, 3 case fans, A64 3200+.... any thoughts?

 

why so much per rail? there are plenty of PSUs out there with 18A per rail but it will be tough finding one under $100

 

this is what I use for my rig.It runs 4 gigs, a quad ,3 sata2 drives a sata dvd 4 cooling fans and an ati 3850 and I run rock solid with 38 amps combined on the 12v rail. the minimum specs listed for video cards are given for single 12v rail psu's. a dual rail with more then 30 amps combined on 12v rail should do fine for your system

 

Here's an Excellant PSU, Corsair 520W, pretty close to your Buget, will power your system with no problem:drool
