Someone might be having the issue I'm having in my garage, so here it goes:

After I've added couple more rigs to my small garage setup (now 14 1080 ti total), my garage door opener stopped working from outside. Cue in pissed wife.

Did anyone tackle an issue like that? RF interference seem to block the remote signal from outside, extending the antenna to outside did not help (it probably hurt as I did not care for the wavelength of the remote signal vs added antenna cable length)

Any solutions?

psu's  may be issue not  gpu rigs.

get an fm radio  and try to find a channel that gets interfered with whne you turn on a psu.

rosewill tokamak does it.

if you find out a certain psu is doing it build a faraday cage around the psu.

this may work it is hit or miss

Hmm, I have three of those PSUs 1500W Tokamak. Now to think of it, the computer case is supposed to filter some  of that noise. But in my case the PSUs are placed on a wire rack. Would there be any benefit running a wire to from the PSU to ground I wonder.

Actually scratch that, the PSU has ground through AC plug.

Thinking out loud, the wire rack may act as Faraday cage, accumulating free electrons then radiating out since it's not grounded, basically acting as a giant antenna transmitting noise? The operating frequency for the garage door opener I'm looking at is between 300MHz and 400MHz range, so 1m - 0.75m wavelength, large enough to be captured by the wire rack. I may try to ground the wire rack as well, may be run a wire to one of the PSUs mounting screws. Or get some ferrite core to wrap the power cords from the PSUs.
