Hi.
I have installed a BPPC with a BVision card on a desktop Amiga 1200 and i actively cooling all the CPU/GFX chips. I power my Amiga With a A500 PSU from its original power socket ONLY. I also power my HD/CD drives from a separate pc PSU. The whole setup is reasonably stable and i don't complain about it.
However, i read all over the forum that it's a good idea to power the motherboard from its DD power socket too, to improve stability further. I intent to do it using the pc PSU that i mentioned earlier, but before i proceed i need to ask you for some feedback because i don't want to cause any damage to my precious Amiga and cards. :-)
a) Is it a safe thing to do or there are potential dangers from using 2 different PSUs?
b) (probably stupid) What will happen if i switch on my pc PSU? will my Amiga be switched on, too? Even with the A500 PSU being off?
