do MicroATX and ATX have different power connectors?

On the motherboards that is. Found a cheap MATX ps which would work perfectly for the p133 I want to use it on.

The power connectors are identical. I just built a system using a MicroATX board using a standard ATX case. Only thing to watch out for is that MicroATX boards are meant for more budget oriented systems, so a p.s. said to be for a MicroATX board often has a low wattage (i think 145w is common for these). Would probably run a P133 fine though.

I don't believe so. But look at the connector that comes from the PS and goes to the mobo. If it is 20-wire one piece connector, then it should be for ATX. If it's two 6-wire pieces, then it's for the old AT.

Thanks, I wanted to be sure before I ordered it.

Im sure 145w will be plenty though, its only going to power the cpu, s3 virge, 16mb ram, and a floppy.
