Brother dropped of PC for me to clean up and install DVD burner for him.

Set it all up to see what the current config was and the PSU blew - was very dusty in there.

Anyway the PSU In there look like this on the back

Whereas my one I replaced in my old Gateway looks similar to this on the back

What is the difference ?

Obviously the monitor on my bro's PC gets it's power from the output on the PSU, if I replace with my old PSU can I just plug a power cable directly into the monitor power cable ?

The other thing is that none of the screw holes on my PSU line up with the chassis holes so that's another reason not to use my old PSU.

Thirdly my old PSU is an Antec True Power 430 which cost me about $159 whereas the one that's blown in his machiine looks like a cheap $40 job.

Thoughts ???
