[QUOTE="dtravis7, post: 1104174, member: 8287"] Like Mac SK and others are saying, the replacement Power Supply out of that other G5 might also be bad or the wrong supply. I have not worked on any G5 towers but I know Apple did change even the pinouts on newer G4 systems. Does that old G5 you were given have the same specs? Did you try the supply in the parts G5 first to see if that machine does anything? I am almost 100% sure like Chscag that the BANG was a Electrolytic Capacitor exploding in your original power supply. I just HOPE that when it blew it did not cause a spike and hurt the logic board. I had 3 PC's here all with the same brand power supply. All 3 Power Supplies died with a BANG (One also poured out smoke). ALL 3 when they blew took out the Motherboard and some PCI cards and the controller on one hard drive! Expensive lesson for me! Don't get Cheap power supplies. Does that parts G5 have all the parts in it? If so try the power supply back in that machine. Does it boot? Post? [/QUOTE]
