tl;dr: is it safe to run 2 PSUs on one system?
Yes
, but you need to turn both of them on at the same time and bridge the GPU power supply. You can also get/make a connector so both PSUs get their POWER_OK (turn on) signal from the motherboard.
Can you have 2 power supplies 1 computer?
Two PSUs are possible
, but I would not try to combine them in any way. First, when two PSUs are in the same path, any voltage difference between the PSUs will result in current draw. This is not only inefficient, but could damage whatever else is in the circuit.
