What''s the reason to make power supplies external?

If you use a external approved power supply so that low voltage only goes to your unit, you are pretty much off the hook safety-wise. The external power supply provides the isolation, and as long as voltages in your unit are 48V or less and limited to a particular current (I forget the limit), you''re basically fine.

Can i use external PSU for my GPU | Tom''s Hardware Forum

Note : I used this power supply to run my r9 270x on another pc, which i am currently using for mining. I want to buy another r9 280x or r9 290x and connect the power supply 6pin connectors to the gpu but in the old system i.e ( Dell Optiplex).
