Asus z87-Pro red power led and won't power up

Jwalker2266 · Jan 3, 2015

Just made my first build and it won't power up. I have tested the psu and swapped out motherboards and the cpu yet nothing. At first the q code flashed 00 about two times and the cpu fan began to power up but turned off after about a second. Now there is no Q code and only a red power LED. Please help

It looks like a short. Try testing the board outside the case, only CPU and CPU fan installed, both 24 and 8 pin power cables connected. See if the CPU fan does spin and if still 00.
What CPU using?

Jwalker2266 · Jan 3, 2015

I'm trying the mer board alone right now
Intel i7 4770k

And, does it work?

Jwalker2266 · Jan 3, 2015

No still no q code, fan is not running, and red power led still

alexoiu · Jan 3, 2015

Is the 8 (4+4) pin power cable connected?

Jwalker2266 · Jan 3, 2015

alexoiu :

Yes

Are you using the stock Intel CPU cooler? If not, can you test with it too?

Jwalker2266 · Jan 3, 2015

No it's not the stock fan. And the fan/cooler I am using is plugged into the cpu fan slot

Jwalker2266 · Jan 3, 2015

And no I can't I gave my stock cooler away(stupidly) thinking I would not need it

Check if the backplate is properly installed.Are you sure that the power supply does work? Can you test different one?

Jwalker2266 · Jan 3, 2015

I believe the back plate is properly installed and also could the problem be wattage? And I will go find another power supply

Jwalker2266 · Jan 3, 2015

Also the other power supply I have is plugged into anothe pc. I would have to remove it (pain in the butt). Is there any other way to test it, other than another power supply? I can pull out the other psu but it will be a pain

alexoiu · Jan 3, 2015

You don't have to pull it. Just place the board near the PC (put it on its cardboard) and disconnect the 24 and 8 pin power cables from the PC and connect them to the board. Start the board by shorting with a screwdriver the 2 pins on the motherboard corresponding to the power switch.

Jwalker2266 · Jan 3, 2015

Can you explain that last part?

alexoiu · Jan 3, 2015

The power button on case connects to the motherboard with 2 wires. When pressed, the button shorts the 2 pins on the motherboard.

Jwalker2266 · Jan 3, 2015

Ok I have the board plugged in with the 24 pin and the spare psu only has 4 pin cpu connected not 8 so that's plugged in and the cpu fan is plugged in. But no power and no fan spinning and stil red led and no q code

CPU does not get power. Hard to say what's wrong. Either board, or a short. Try reinstalling the CPU and CPU cooler. Check the socket for bent pins. What's the CPU cooler?

alexoiu :

Thanks so much for the help it ruled out of a lot of things weather it worked or not thanks
And the cooler is Cooler Master
Hyper 212 EVO
I will try and reseat the cooler and check for np bent pins now hopefully it works

You're welcome.

Having the same issue, could I just ask if my backplate could be the issue and how this can effect the computer?

alexoiu · Dec 5, 2015

joshtoomer96 :

Have you solved the issue?

joshtoomer96 · Dec 5, 2015
