I personally don't think power supplies are worth breaking down. Sell them as electric motors or copper bearing scrap. Depends on your yard what they will categorize them as.
All your wire should go as #2 insulated wire. Some yards have separate prices for telephone or communication wire. You can call them and ask what Cat 5 cable would be classified as. If they don't classify the cat 5 wire and telephone wire as #2 insulated than call another yard and see if you can find one that does buy the cat 5 and telephone wire as #2 insulated. The price between what they pay for communication wire and #2 insulated might be worth your time to go to a different yard depending on how much weight you have.
If you are into
E-scrap you could cut the ends off your cat 5 wire and throw them with your other gold bearing ends, if not just leave them on. Same for your other bigger ends you have pictured as long as they are not magnetic. You shouldn't need to cut the ends off the power cords either. They do not contain gold so your losing weight if you do cut them off. Your yard should buy the power cords as #2 with the ends still attached. Some yards might not though so you might want to ask before you arrive. You can always take a wire cutter along with you and cut them off at the yard if they say they are going to down grade the cords because of the ends.
