Hey guys, about 2 weeks ago, I accidentally spilled water into my gaming rig. About two minutes after the spill (I was shocked about the spill, panicked, and forgot to shut it off) the entire computer simply powered off. After 2 days of drying, I tried to power it on and it would turn on for about 1/10th of a second, to just turn off again. Anyways, after waiting two weeks & ordering a new motherboard after reading a ton of threads with the same problem, the problem still avails - except this time if the 8 pin connector is not connected, the fans on my h100i and gpu will start spinning like it would normally. I am at a loss as to why a new motherboard would not help it, and what other parts would possibly be broken before I go buy new parts, especially because I don't have the budget to do that right now. I have also gone through that no post/video sticky as well as have tried the paper click thing on the 24 pin connector. Have also resat CPU about 4 times during the process so taking it out and putting it back in will unfortunately not help me here. Let me know if anything else is needed to be descriped - thanks.

SPECS:
Intel 4670K
(NEW Asus Z-97A)(OLD MSI G-45 gaming)
8GB corsair vengance pro DDR3-2400
Corsair H100i
Corsair RM 750W
Asus GTX 780 DirectCU II

It could also be the CPU itself. If it shorted, and the 8pin cable provides the power for the CPU, then the power supply might be detecting a short there, and preventing itself from powering up the PC. Seems like that would explain why the fans power up with the 8pin disconnected. Just a thought.

All right, i'll get back to you if a new one seems to make any difference.

That's what I was thinking initially, however, I wanted to confirm it due to the price of getting a new one. Thanks for the insight i'll think about it over the day.

Hey, I just got a new PSU, and it seemed to not make a difference. I have now ordered a replacement CPU, that's the only thing that I can think of that would be causing this if the only parts left are video card, cpu and mem.
