Bad power supply or what?

[Bruce]

physically removing ALL parts from the case and reassembling them on a piece of cardboard would have been better.
this gives the opportunity to check all parts, backside of the motherboard for example, and to clean the parts.
so I would still be suggesting that as a last chance throw of the dice.

your mobo and processor supports embedded graphics so don’t reconnect the GPU.

the next logical conclusion is some other part has failed; motherboard, processor, memory - who knows.

what is the make/model of the new PSU?

Corsair RM750e. It looked like the best bang for the $$$ and I could have delivered in 2 days. It replaced a BeQuiet 650W.
