Hi there, I'm not sure if what I have in mind makes sense. I have a bricked hd 4870 and I have to flash it with a PC because there is no way to boot my mac pro with this card. I aslo have a PC, but it's psu is not big enough like for connecting this card. So I guess, can I connect the supply cables to my macpro while the card is connected to the pc? Will it explode? Thanks in advance!
