Power Supply - Old Case

[HLA]

I bought an older case with a 200 watt power supply to set up a second computer. There are three power plugs which plug into the motherboard (PS1, PS2, and PS3). Only PS1 can be pluged into the motherboard correctly (putting the black ground wires in the middle) either one of the other two can be pluged in along side of PS1. My question is, which of the other two should be pluged with PS1. PS2 has only red and black wires,PS3 has red, black and orange.

Second question there is no small power plug to supply power to the floppy only the large power plugs, the type that plug into a CD or HD. Is there a special plug available to convert the large plug to the small supply power line to attach to the floppy?

Any help will be appreciated,

Thanks,

I'd guess PS3, although you could just check with a meter and see what the voltages are.
As for the floppy, adapters are available for a couple of $$ at any "big box" or radio Shack.

any idea how old your case and power supply are? I check records if you have any idea as to who made case ( what company put their name on it) if it's in our records I'll let you know.
