As far as I'm aware that was only a problem if people didn't plug it in properly. Many people have been gaming on 4090's day and night for a while now so I doubt that's still a problem.
Just make sure it's plugged in properly both on the GPU and PSU end and don't cheap out on a powersupply (ideally go with the new models which use extra safety measures, even though the old ones should also be ok still,) and you should be good.
