The IIvi, IIvx, Performa 600, Centris 650 and Quadra 700 use the same power supply. The Powermac 7100 power supply will work in all those too. Except for the Quadra 700, those all used the same case.
IIRC the 7100 power supply is higher wattage, which would be a good thing for that PPC upgrade board. Does your Centris have ethernet built into the mainboard or not? If it does, it has 8 meg RAM onboard, a full 68040 CPU and one meg video RAM onboard. Without built in ethernet had a 68LC040 CPU (no FPU), 4 meg soldered RAM. Both run the CPU at 25 Mhz. The Quadra 650 which replaced it is identical to the Centris 650 with ethernet, but runs the CPU at 33 Mhz. Replacing the mainboard with a Quadra 650 one should make the PPC upgrade run faster. --- On Sat, 3/16/13, Nat Hall <[email protected]> wrote: From: Nat Hall <[email protected]> Subject: Centris 650 Power Supply To: [email protected] Date: Saturday, March 16, 2013, 6:50 PM I've got a Centris 650 with PPC upgrade card that I'd had sitting in storage for about 3 years. It worked fine when I "retired" it to storage. Anyway, I pulled it out recently and fired it up and the power supply fuse blew immediately. It was loud too, sounded like a rifle being shot off in the house. I replaced the fuse, and it promptly blew immediately again as soon as I hit the power button. I figure the power supply is probably bad, so I've been looking for a replacement, but... Wow. I haven't seen a single one pop up for sale anywhere, including eBay, and unfortunately this power supply seems to be unique to the Centris 650. I have half a mind to try and fix it, so I pulled it apart and took a look at it but, aside from a layer of dust, there's nothing wrong with it that I can discern from a visual inspection. I mean, I was half expecting to see a melted transformer, burnt/exploded caps, etc. Anyone have any suggestions? Either a tip on a common failure point on these, or where I might find a replacement?
