Hi there Just upgraded my G4 AGP (the Gigabit ethernet version) to act as my home server. It now has 2x120GB IDE drives, one of which is the boot drive, and 2x1TB WD Black SATA drives running in Mirrored RAID - these are running off a Sonnet PCI SATA card. Now, all seems fine, but I noticed when I had the case open that the PSU claims to have a maximum capacity of 195W, and from memory the 15" Apple Studio Display takes about 40W to run off the ADC connector. So my concern is whether going to 4 hard drives at the same time as running an ADC monitor will overload the PSU. For now, therefore, I'm running the machine into my regular monitor through the D-SUB output and with the keyboard and mouse into the normal USB ports in an attempt to minimise the power draw, but I'm curious to know whether anyone's got any experience in this area - have you ever blown one of these PSUs by overloading? Am I worrying about nothing? My main concern is that I seem to remember these PSUs aren't normal ATX jobs, so replacing it with a more powerful one will require a cable adapter or some soldering, neither of which I'm really up for. Incidentally - what a truly great machine to work on, having painfully upgraded many PCs over the years. Pop the side down, slap in more RAM, slide the drive "sleds" out and add 4 hard drives. It's an absolute joy of a machine.
