No Power On Asrock Extreme4 [X99 chipset] Motherboard ! Help.

[buddy101]

I have been pulling my hair over this for last couple of days. I am building a new desktop for work and here is what I have connected so far -

CPU: Intel Core i7-5820K 3.3GHz 6-Core Processor
CPU Cooler: Cooler Master RR-T4-18PK-R1 70.0 CFM Rifle Bearing CPU Cooler
Motherboard: ASRock X99 Extreme4 ATX LGA2011-3 Motherboard
Memory: Ballistix DDR4 2400MHz UDIMM 16-16-16-39 8GB on 1 slot
Case: Fractal Design Define R4 (Black Pearl) ATX Mid Tower Case
Power Supply: Corsair Builder 500W-M 80+ Bronze Certified ATX Power Supply

I have connected the 24pin power and 8-pin power to the mother board and yet when i turn on power nothing happens. I do not see a fan or no led (according to a youtube reviewer this one has a led, the manual does not mention the led !) on the board. No nothing.

I first suspected the power supply was bad. So went to central computers with the power supply I had (Corsair CX-500) and they used their power supply tester and tested the 24-pin connector - the 3.3v rail was orange (=bad). So I bought CX-500M which is modular and double the price thinking I could build this thing today and return the original supply back to newegg.

But even with the new power supply, nothing. Any one has any clues as to what might be going wrong here ?

Disregard my earlier post. With all hardware installed, MB is working properly.

You need a CPU for it to post. Otherwise it does nothing. some say it is dangerous to power your motherboard w/o a CPU

I sent in the mobo and psu to get them replaced. Something was fried (probably both) from a power surge.
Be sure to buy a power strip rated to protect against things like that.

Thanks for the quick answer!

I tried it with 1 RAM stick. Tried both sticks for its own.
And yes i cleared the cmos (by clicking the button at the back).

Tomorrow, i will try to buy another board and answer my results.

My solution:
I bought an GigaByte Mainboard, plugged all together. Worked perfect on first try.

SWEET! Good for you. My experience was similar, bought a new mobo of a different brand and my 5820k worked like a charm.

Ehhh, I have a feeling we were missing something super obvious. But hey, its working now. No need to fix something that aint broke. Or newly working. Or something.

:lol:

That's what I am going to do. I had returned my Extreme4 because I could not get it to post and I was going nuts trying to troubleshoot. I had originally requested a replacement but after reading these posts, I don't want any more problems. I will buy another brand of ATX LGA2011-3 motherboard.

So happy I found this thread!
