Problems with initial boot Asus Z87 Pro

Hello everyone, I need help!! I am doing my first build. I wanted something simple but with room to grow as I learn more. I put everything together extremely slow and careful to make sure I didn't do something wrong, but now I am at the point I think I might have done something wrong.... Here is my build:

Coolermaster HAF X case
Asus Z87-Pro MOBO
Intel I7-4770K Chip
ADATA DDR3 2400 8GB x 2 memory sticks
Adata 128GB SSD
Coolermaster M2 1000w Power supply
Cheap LG optical disk drive (don't remember the model)

I left all of the MOBO option switches for overclocking and such in the factory off position. When I hit the power switch to turn it on, nothing happens on the MOBO. I also noticed the lights plugged in to the same outlet dim for a second. I am an automotive electrical technician so to me that indicates a large draw, or short for short (no pun intended). I researched a lot about things that could short on a mother board and a lot seem to point to messed up pins on the 1150 socket. To try to isolate this without having to remove the chip a bunch and increase my chances of messing it up, I unplugged the CPU power (8 pin connector) and left the 24 pin connector in. When I turned on the computer this time the LED's and CPU fan and digital readout on the MOBO all came to life. Having isolated it to the CPU circuit I reluctantly removed my CPU to look for damaged pins. I can not find a single pin out of place or damaged (under high power magnification). I put it all back together (yes the arrows are lined up) but with the same results. Is there something I could be missing or don't know about since this is my first build?

  1. Just a quick thought that comes to mind in what you've described, have you checked that it's not the 8-pin EATX12V connector that is the issue?
  2. Is the 8-pin CPU power connector plugged in?
  3. Pibee, please excuse my ignorance, how do I check that?

    Spooky, yes it is plugged in, that is when I have the issue. If I unplug it everything else seems to work

    Ster2416 my thought is to eliminate the 8 pin connector as the culprit, try replacing the 8 pin with 2 x 4 pins or even one 4 pin from the PSU to see if in fact it's the 8 pin that is at fault.

    Thank you so much!!! I switched from the 8 pin to the 2 4 pin and she fired right up! I can not tell you how grateful I am for this. Have a happy Easter, and again THANK YOU.
  6. Ster2416 Excellent delighted the suggestion resolved the issue and Happy Easter to you to :)
