I have an old system (AMD K6-2 350 ). I want to add a CD/RW to it and apparently I do not have enough power for it. So I need to get a new power supply. The old one has been running reliably, so it would be nice if I could keep the old one also.

The old power supply has been running my system with rock solid stability since '99. So I was disappointed to find it can only power either my DVD drive or my CD/RW but not both.

So can I just get a new power supply and hook up my CD/RW to that? Am I right in assuming that as long as they are grounded in the same place they should be ok?

Yes that can be done, it is quite easy. If you got two ATX PSUs you just connect the power on wire (green) and the ground beside of it with the PSU that is connected to the mobo. Then you could connect the power good wire (grey) with the power good wire on the PSU connected with the motherboard but this is needed to get it work.

My dual-PSU PC is so powerfull that the neighbourhood dims when I turn it on :eek:
