So I have been having issues with my new build and I need help.

I built a pc with a new AMD 1950x threadripper and the ASUS rog zenith extreme MOBO, also has a gtx 1080ti and 32gb of ddr4 memory. Psu is a corsair rm850x. My problem is that it turned on long enough for me to install windows 10 and set my ram to its specified frequency, it then shut off and I had to unplug all power to get it back on again, unfortunately when I did that it immediately shut off and it had an odd smell coming from the PC. I originally thought it was the CPU or MOBO so I exchanged both for new, but after installing it still doesnt come on. When i try to power it up the PSU makes a high pitched flash sound everything comes on for less than half a second and then nothing. The odd thing is that my PSU will power everything individually including MOBO rgb lighting, water pump and fan controller, and graphics card, but as soon as I plug the CPU plugs in, it does the flash sound and then I cant try and turn anything on until I unplug power from the PSU and plug it back in. I would say CPU but it's brand new... I have already spent $4k on this thing and cant Keep buying new parts...

Found out something was wrong with my PSU. Bought a new 1000w PSU and the computer powered right up. Not sure what happened to cause the issue with the other PSU, but replacing it worked.
