What is at fault?

So I got my new rig today and set it up then powered it up to just check everything is fine. What happened immediately was the computer started and then rebooted soon after (span of 5-10 seconds). Only one of the fans turned on regardless of if I only had 1 fan plugged in and left the mobo itself powered.

I noticed my heatsink fan attempting to start, but never actually going possibly due to not getting enough power before it restarted. On top of that, I felt the PSU fan 'restart' with the reboots.

I pulled everything out so that I could literally only have the mobo getting powered and it still occurred, thus it can't be a not enough power for my system issue. I figure there are four possible culprits, the PSU, the CPU, the mobo, or the actual case (Antec P180B) Power Switch is somehow causing it to continuously restart.

Any help would be greatly appreciated.

UPDATE: Checked again and this time couldn't get any fans to spin at a truly serious rate, so only 1 fan getting powered is no longer true.

List the specs of your pc. You got another power supply you could try? Disconnect the power switch from the motherboard and touch a small screwdriver to the pins

Ok here is another update. I found the psu w/o mobo trick and here are the results: 3 fans ran without a problem and proper speeds.

Here are my specs that are relevant:
Gigabyte DS3
E6600
TT Purepower 600W (Active model)
P180B

I'm convinced that it isn't a cpu issue as all the fans should still run and not keep rebooting automatically. I am very suspect of the possibility that the P180's power switch is somehow causing a restart every 5-10 seconds. The other possibility is that the 12v lines are faulty and forcing the computer to reboot since they are overloading and my psu didn't demonstrate anything.

No I don't have anything to test it against as my other computer is a SFF with a built in 200W psu and the other comp I have is 8 or so years old, so probably has about as much power.

Looks like I have to cross post as the tech support forums aren't visited and are barely viewed.
