I know this guy, and he has a 933mhz Dell (i think it's 933 but its definitely a Pentium 3, Socket 370).

He has 2 optical drives (I think), one hard drive, and a Zip drive in there. and a 200w PSU.

He wants to add another hard drive in there but I don't think the PSU is powerful enough to handle another one.

1) Will the PSU handle it, even if it's just barely making it?
2) My real question is this..he has a spare 300w PSU..but Dells have a proprietary connector..can the computer operate without this connector?

Thanks.
