I found that there was a bad PCI-E cable from the PS to the MB. I replaced this cable and the MB now goes further into the POST process. Still having issues, but the PS issue appears to be resolved.

I am using an MSI X399 Gaming Pro Carbon AC. It has LED for RAM, CPU failure, and others... But nothing it lighting up there... I have moved ram around. Tried single, different slots. I was very careful putting in the new CPU and attaching the water cooler to it. Pins all looked good on the MB. This is a Threadripper 1950x CPU. I also tried disconnecting wires for reset, power, and HDLED - just in case there was a short there. The MB has built in reset and power buttons too. But nothing. Removing the MB from the chassis made no difference.

I replaced my old PS with this one, thinking the PS had failed. But still would not power on. So, I think the MB is bad, replaced.. no power. Replaced CPU, no power. Replaced GPU, no power. So, now I have a new PS, new MB, new CPU, new GPU... When I turn on the PS, the red power button on the MB comes on. However, when I press that button, or the one on the case, I hear a click, nothing happens. The MB does not power on. I took everything out, and re-did all the connections and mounts... Same problem. Only the power button on the MB is lit and the led on the overclock dial. None of the MB POST led or other led on the MB are lit. I also tried another outlet on a different circuit - just in case there was a grounding issue or something on the neutral, which I doubted but needed to check I am stumped at this point...
