A non ticking time bomb! 
I think next to the overheating ICs, the joystick issue is the second biggest threat to the 264 series.
Try not using more advanced joystick models, especially: never use autofire
This function causing short circuited TED, and will kill it in no time. Valid to C16 too.
There was a circuit developped some years ago to protect the TED in this conditon from joysticks, but I am not aware of any working prototype.
If I remember well, the Plus/4's extra ROMs also tend to use more current and generate more heat, than if EPROM versions of them would be used (IC swapping). Maybe I am wrong...
I think from PSU side Plus/4 is much more reliable than the too weakly designed C16 PSU, so when I count the Plus//4s' overheated CPU and extra ROMs VS C16 PSU, the risks are somehow balanced.
(TED is DEAD is the same risk for both models)
