Hi, I lately read an article saying the G4 Gigabit's PSU will be destroyed, when using 4 HDDs. I have 4 SATA Drives installed on a G4 AGP for quiet a while now and never had problems so far *knock on wood*, so I wondered what you were experiencing. Nor had I read of this as a reason for PSU failure on this forum or else. Here is the link http://www.mechriki.de/wordpress/?p=8 It sounds right what he is saying about the 12V rail, but on the other hand I never heard of died PSUs because of HDDs. What do you say?
