I just bought all my parts, super excited and ready to put everything together. This is my 4th build I've done so I know how it all works, but this time has me stumped.
Ive plugged everything in properly, and when I plug in and turn on, the mobo leds light up pinkish white, then shortly after turn blue. When I turn on the power via power button (also tried using screwdriver to manually start p ) it makes a click noise in the back, and then stops. The leds turn blue again, nothing else. No Dr.Debug, no fans turning, nothing. So far I have tried the same process without any of the fans plugged in, no hd audio etc. Ive also tried moving the ram, one stick, 2 sticks, no gpu, but to no avail. Ive seen some others have had issues with taichi mobos saying they were dead on arrival, but i dont know how to find out if thats my case. Does anyone have an idea or can help?

Specs:
Case - thermaltake core p3
Ram - hyperX fury ddr4 2400mhz
Gpu - nvidia gtx 1060 EVGA
Mobo - asrock x370 taichi
Psu - corsair cs750m modular 750W
Cpu - amd ryzen 5 1600x 6 core
Deepcool gamerstorm AIO liquid cooler

Thank you for any help.

Have you followed the rest of the steps here?

Did you breadboard (outside of the case)? Are you sure you've got nothing shorting the board?

Try testing the board outside the case, for ruling out a short. Make sure that both 24 and 8 pin power cables are properly connected.

I have not yet tried a barebones setup. So mobo on a cardboard, and only plug in 8 and 24 pin psu plugs, Cpu, and gpu? The 8 pin is for cpu slot on mobo and 24 pin is specifically mobo power?
I did one time while trying it out get a little spark where the Led/power plugs on the mobo are, but no smoke or smell, and i still got the same outcome before and after. I will try your idea and get back to you on it, thank you.

Im starting to think i may not have put the standoffs in the right place. The order is case wall, standoffs, mobo, then screws?

Barty1884 · Sep 8, 2017

Yes, 8pin CPU, 24pin mobo. Whatever connectors are required for your specific GPU.

Your PSU is pretty mediocre in quality, so could be the culprit..... I'd suspect so ahead of the motherboard, infact. But try breadboarding first.

christophershults :

That's the order. The standoffs secure to the case, and the motherboard is secured via screws into the standoffs.

Ensure you haven't dropped a screw or anything too - if it's making contact with the traces on the the underside of the board, it may well be causing a short.

alexoiu · Sep 8, 2017

Yes, that's the order. Does the board work outside the case?

christophershults · Sep 8, 2017

Lets say im getting a short cause the mobo is touching the case. Does that harm the mobo? It wouldnt kill it would it?

Barty1884 · Sep 8, 2017

It *could*, but in all likelihood, removing any screw/contact etc should fix it. It's a bit of a luck thing too though.

Ok, awesome. Im getting power, but when i plug in the watercooler (to cpu 1? Or cpu opt_w pump) the power to gpu slowly goes down until the fans die. Then the pc tries to restart. When the fan is unplugged and only the radiator fans are going, the gpu fans keep running. Any ideas? And thank you for the suggestion, turns out the mobo WAS shorting.
