What's happening?

So I just ordered some new computer parts:
EVGA 640MB 8800GTS
MSI P35 Neo-F LGA775
INTEL Core 2 Duo E6400 2.13G LGA
1GB G.SKILL DDR2800 pc6400

I used my old case, hard drives, dvd drive, and power supply. I hook everything up and turn it on and it starts up for MAYBE 1 second then turns off. So I notice my power supply is only 380watts, which is low, so I started disconnecting things like my dvd drive and hard drive and pulled out everything but the video card and tried again; this time it did the same thing.

So then I disconnected everything, and the only thing hooked up was my mobo, processor, ram...just to see if it would stay on. So I pressed the button and my heatsink fan turns on for a second, then turns off. So I figure something maybe grounding out so I pull the mobo out of the case and set it on the static bag on the ground...press the power button and it does the same thing.

I was told the computer would still post without ram, so I tried turning it on with just the processor and mobo conneced and it still would only turn on for a second then turn off.

Now I've built around 5 computers or so and never had any problems, and now I can't even get this one to post. What I really really hope it is, is that my power supply is 20pin and my mobo is 24pin. Even though MSI says I can use my 20pin connector I'm really hoping it's something as cheap/easy as that.

But does anybody have any suggestions?
 
If its a knockoff PSU then of course its gonna do that. Get a 24 pin knockoff and try it. Don't trust what MSI tells you. Either that or a faulty mobo/psu

Where in that does he say he plugged in his 4 pin CPU power connector, (Almost) all 24 pins board will fire up with just the 20 plugged in. How are you sure 100% its his 20 pin P/S connector to not ask anymore questions!

Do you have the 4 pin CPU power connector pluged in?

yea the 4pin is connected, my 20pin is connected into the 24pin connection slot (it only fits in 1 way), my heatsink is connected to "cpuFan", and the only case connection I have connected is the power button.

I'm going to go buy a 500watt 24pin PSU with the 6pin connection for pci-e today and hopefully that will fix it...I hope...
 
Dont know how many amps your P/S has but I would say the 8800 is pulling to down quite abit. But I would get a higher watt and amp P/S

yea it says it requires a min of 26amps and 400watt power supply, and I'm running like 380watts and 30amps. Which is why I need a larger power supply, but the problem still occurs even when the 8800 isn't in there.

Unless, when I started it up the first time the 8800 broke my PSU...can that happen?

Yep, drawing too much of a current accelerates the wear on the system so it burns out almost instantly.

I'm hoping by 'it' you mean the power supply and not 'the system.' So if my power supply did burn out, it would still be able to turn my heatsink fan on for an instant?
 
yep...blew up the power supply. I went and bought an antec 650watt and everything started right up. I'm just happy it was an easy fix.
