Computer Shuts Down with new Power Supply

I'm really new and I'm sure I must have done something stupid.
I bought a new power supply from Spire zeno 600W.
I connected it to my motherboard with an AM2 socket I believe and an AMD Athlon 64 2x 4200+ processor with a Geforce 7600 GS graphics card.
The computer shuts down spontaniously at different times and I connected everythin how the manual said. What can I do to solve this problem?

That power supply might not be able to power the system due to poor quality or it may be faulty. I'll have to try and find a picture of the label.

EDIT: I take it the system worked before.

Should work ok, but it might be faulty, listed below are the specs for it.

Output: +12V1dc Max 20A;+12V2dc Max 20A; +5Vdc Max 50A
+3.3Vdc Max 30A;-5Vdc Max 0.5A;-12Vdc Max 0.8A
+5Vsb Max 2.5A

Since I just built a Computer for my nephew using a ENERMAX Liberty ELT500AWT ATX12V 500W psu, running AMD FX57 Cpu, Segate 250gb sata HD, Samsung 18x DVD-RW Writemaster and 2 EVGA 7600gs in Sli,on a Evga 123-K8-NF47-AX motherboard with no problems.

Those specs mean nothing without combined 12V wattage/amperage.

What exactly did I do wrong?
If I replace the Geforce 7600 with a Sapphire Radeon HD 2900 XT will it work better and stop shutting down? I figured out that the computer runs fine when I press the turbo fan of the power supply but as soon as I turn it off the computer can shut down immediately.

Turbo fan?

EDIT: Ah I see, well then it seems your psu is overheating and shutting itself off. That could be because you are overloading it, although I dont think you would be, your system is fairly low power.
June 15, 2007 8:50:57 AM

The new power supply has a button that says turbo fan and when I press it the fan makes alot noise but the computer can run.

Check out my edit in the previous post.

yes I think it's strange. Maybe I bought the wrong power supply for my motherboard? I just chose one and I dont know anything about it, could that be? All the connectors fit though and the box sais its for AMD Athlon
June 15, 2007 8:56:07 AM

The box can really say what it wants, thats marketing for you. The important thing to note is that when you turn on "turbo fan" it runs ok, which tends to suggest that its overheating. Feel the air coming out of the back of the power supply when not on turbo fan, if its fairly hot, its likely overheating.
June 15, 2007 8:59:00 AM

The power supply doesnt become hot not even warm and the air that comes out is just a little bit warm. My older power supply is more hot (350w.)

Is that under load though? Does the computer shutdown when under load (like in a game) or when doing something like surfing the net?
June 15, 2007 9:03:44 AM

Sometimes it can shutdown as soon as I start the computer and sometimes when I start a game and sometimes when I play a game for a while and sometimes when I open the invidia control panel or when windows starts up with the Flag load bar.
June 15, 2007 9:05:06 AM

And you are sure that it always works when turbo fan is enabled?
June 15, 2007 9:06:17 AM

yes, yesterday I worked with the turbo fan enabled and I couldplay games, listen to music and open the panel several times and it never shut down.. as soon as I pressed the turbo button off the computer shut down immediately.

It sounds as though the power supply may be faulty in some way, maybe you should RMA it.
June 15, 2007 9:08:56 AM

What does it mean to RMA my power supply?
June 15, 2007 9:13:24 AM

In bios disable power off on errors,
June 15, 2007 9:13:38 AM

Send it back saying its faulty, I have never had to do this before (guess I'm lucky) but others can help you there.
June 15, 2007 9:14:42 AM

Thanks I will try my new videocard with it and if it doesnt work I will do that.

Is there such an option? Never seen it in my BIOS, only "Halt on all errors"

@jrlcgmx: Check your temperatures for your cpu etc.
June 15, 2007 9:17:52 AM

I will check it when I'm home. What do I do with the option?
I think my CPU is 40 degrees I believe I saw in the bios.
June 15, 2007 9:19:17 AM

Thats ok for low-moderate load.

My guess is also a weak or even defective PSU. You'll find out when you plug in that power consuming monster video card. FYI, running high end computers and especially those with high power video cards is a BAD idea.
June 15, 2007 3:09:13 PM

what do you mean? The videocard says it needs a 550W Power Supply.
Is 600W not good then?

The Evga 7600gs does not need any supplement power from PSU. There is no extra power connection plug on that card.
June 15, 2007 4:38:53 PM

yes that is it halt on errors but I found that my system would shut down if shut down on errors in windows was checked and halt on errors enabled in bios..
It very well could be psu but I'd try the options before rushing out to buy a new one. Lower cpu clock speed, adjust memory timing to a higher number, 'you can choose the best if you are good', disable any hardware monitoring in bios, none or very little auto setting in bios. video card flash the bio's using a bios editor concentrating to voltages, change #2,#3 to the same voltages as #1, 'if you know what you are doing you can play with other options'.
Remember with a bios editor you are not flashing the bios it's perfectly safe to save the file. The flash utility with do the flashing of the new bios you made.

First, if you are having problems running stable with your current system and it is power related (still guessing here) then that new card will eat it alive. It draws WAY WAY more power than your 7600.

Total wattage rating on a PSU is not the issue here. It is the amount of current available on the 12v rail.

Also, low end PSUs exaggerate their power ratings, often to the extreme. So you may not be getting a true clean 600w.

Aren't there some good PSU related stickies at this forum somehwere?
June 15, 2007 5:15:18 PM

Yep THG did a stress test, and rumors state that vantec once lied. I believe that major psu manufactures paid attention of THG reviews and changes were made so psu labeling is more accurate.
June 15, 2007 5:26:08 PM

PSU states 12V1 and 12V2 @ 20A each, which should be OK, but that PSU is a bit cheap for a 600W, and has lots of flashy externals. Better to spend a bit more on a better quality PSU. I wouls return it as faulty/too noisy and buy different. If it needs fan on turbo to work, its not suitable.

This is the sticky I was referring to, right at the top of this section:

Additionally, I have a great deal of respect for how Jonny Guru tests PSUs. I trust his ratings.
June 15, 2007 7:49:51 PM

What is a rail? How can I know wha tthe first rail is and the second? How should I imagine it?
June 15, 2007 8:32:18 PM

Can I put somethings work on the first rail and other things on the second rail and how?
