Uhh, specifically what make and model of PSU?
It could be you have a cheap POS that doesn't work.
Thermaltake TR2 600W. I have 2 PSUs and neither work. The older 1 works fine on my old build
Does your old build have another GPU you can try? and can you try your new GPU in your old build?
Maybe try a differnt cable/input?
It sounds like your monitor is smart enough to identify what is outputing video, but it's not getting the signal.
Can you unhook the HDD/SSDs you have as well?
And try to use the hotkeys to get into the BIOS even if you can't see anything.
