Micro ATX PSU

[Punkychan]

I've got a micro ATX motherboard (an Intel 810 ) but the case that I have is supplied with 350 watt for P4 mother board.Can I use it ? Because I tried it once but there seems to be a little conflict somewhere ( the lights started to flicker, cd drives and floppy drives goes crazy and made many funny sounds..) I have another PSU which is for micro ATX., can I use it in that case ? Thanks

I didn't know there was a difference. I thought they used the same PSU:s.
