[SOLVED] Does anyone know what this cable is for?

Solution
I agree..that's for an old floppy drive. Makes me wonder how old and of what quality that power supply is, and what you hope to power with it..it may not go well.
To be safe, what make/model/rating is the PSU, and hardware will it be powering?
