Hello. So earlier today I decided to replace my hs fans (the pull fan had died a while ago and I never bothered to replace it until today. After removing the cm h212 I found out that I hadn't tightened the bolts on the backplate well enough and so they all came loose (and fell off). After reinstalling the hs and fans as well as the motherboard (my cm cosmos doesn't have a cutout for the back of the motherboard) I powered the system and was greeted with... well nothing. All of the fans were powering on, the motherboard lights were on, but the gpu fan wasn't spinning. After I powered it off I realized that I had forgotten to plug in the 8 pin motherboard power connector. After I plugged it back in it still wasn't working. Now I'm not sure but failing to plug in the 8 pin power connector shouldn't kill my motherboard should it?

As for troubleshooting I tried the psu in with a mitx system I have and it booted up fine. I couldn't try my video card because it wont fit the in case and I can't be bothered to take the motherboard out. I also threw in a x800xl I had sitting around into the asus rampage II extreme and the fan spun up but that was the extent of it. I tried each stick of ram individually and that didn't solve anything either. I also checked to make sure the standoffs were all accounted for and no extras were there and I reset the cmos and removed the battery.

I don't have any other power supplies I can try or other 1366 motherboards/cpus.

My system specs are below:

i7 920
Asus Rampage II Extreme
12GB DDR3 4GBx3
EVGA GTX 285
620W Corsair 620HX

Any ideas? :confused:
 
Not plugging in the 8-pin EPS shouldn't kill the board, but it there's still a chance it might have.

The R2E wasn't the most reliable board around with a hot running chipset from what I heard.

And just dying and leaving black screen seems to be a thing with some old Asus boards as I had a Striker 2 die on me that way.

I'm sure it's not the PSU as that's a good PSU with Japanese caps, and since it worked in a different machine.
 
I don't think its the PSU either but I also don't see how I could have damaged the motherboard. I'm not really sure what else I can try tbh.
 
If the board is leaving you with black screen and just the fans working, then it's probably shot.

You might look into a second hand X58 or one from the eVGA B-Stock.

Though, it wouldn't hurt to just pack up that inefficient setup and go Ivy.
