Need help picking a powersupply fast please

I upgraded my rig to a 7600 gs and have random reboots presumably due to not enough power.

I'm on a budget of roughly $70-100 (more saved the better assuming good quality powersupply).

I have an MSI GF 7600gs which says it needs 18-19 amps on a 5v rail (350 watts minimum). My antec 350 watt true isn't doing the job although it says 29 amps for 3 molex cables.

Also I need a 20 + 4 connector as I have k8n neo platinum motherboard. Can you help me pick a p/s or suggest one please.

1. http://www.newegg.com/Product/Product.asp?Item=N82E16817153028 (not sure it has enough amps).
2. http://www.newegg.com/Product/Product.asp?Item=N82E16817163104 (again not sure enough amps).
3. http://www.newegg.com/Product/Product.asp?Item=N82E16817182016 (like this one, sure it'll hold upto it?)
4. http://www.newegg.com/Product/Product.asp?Item=N82E16817148010 (same as 3)

Or do you have any other suggestions ?

My rig:

Amd 64 2800+ Newcastle
MSI MS-7030 (k8n neo platinum)
2 x 512 mb pc-3200 DDR sdram
2 x 120 gb hard drive
MSI 7600GS Video card (agp)
soundblaster 5.1
Lite On Dvd-rw Burner
D-LINK PCI Network Card
2 x 19" Samsung 915n LCD's
 
It might help to know your complete system specs, but I'm doubting your PSU doesn't have enough juice unless it's quite old. The 7600GS dosn't need alot of power.

How much +12V amps does your PSU have?
 
No they're not

CPU 40c, case 42c, Video Card 55c full load

I tried switching the molex connectors and giving the video card its own cable. I have 3 molex connecting cables. When I try to play a game, I crashed on 2 cables within 1 min, and on the 3rd after 20 min.

I'm pretty sure its the power supply.. the memory seems to be fine

 
no bsod, restart when playing games (putting load on video card). I reformated and just put the minimum on. CPU is stable, video card heavy applications are not.

I don't think running these many should be too much to ask: http://img165.imageshack.us/img165/5452/hmmbl9.jpg
But crashed on 2 molex cables within 1 min, and the 3rd held together for 20 mins.
 
Well, it does kind of sound like the PSU given the temps you listed. You might want to go ahead and run memtest on your RAM just to rule that out. It's free and doesn't take too long.

As for the PSU's listed above, the Silverstone is IMO the best by far. I know ewiz.com sell Enhance PSU's (the Silverstone you linked is made by Enhance) for really good prices, but order from there at your own risk. Unfortunately Newegg does not yet carry Enhance models.

As for the others, I would not but any of them. Newegg does have an Enermax 495 for $80 +shipping this week. Definitely more power than you need, but it's at a good price and will allow you plenty of romm for upgrades.
 
You'd want the second one. It's a newer version with better efficiency and better connectors (like 6 SATA, 2 PCI-e, and a 4/8 12V CPU connector).

Now realize they have both have dual +12V rails and both are rated for a combined 32A@+12V (which is plenty for most any system except very high end SLI/xfire rigs).
