So besides my 2 Mac Pros I also have a 2001 Sawtooth that got a fastMac dual 1.4 processor upgrade way back when and it needs a power supply replacement. One day after not using it for a few months it just wouldn't turn on. It was plugged in during that time...and I changed the battery...but nothing when you hit the button. So if I can find an inexpensive power supply I'd replace it myself....I could use it to run older apps and rescue the files from the HDs. So I found a good install video In this video he specifies a Delta Electronics DPS-338B-B as the one to look for. My question though is: Does it have to be that Delta model # with the same specs or can I use say a DE DPS200 PB-110B? It's hard to find that exact one.
