Until now, I have been selling my power supplies complete with the wire. The yard I used to deal with had two price one with wire and one without wire. Lately I started to sell to a different yard which pays more, and they have the same price with and without the wire.
I took a little more than one Gaylord of power supplies and cut the wires off to see what it yielded. This was a fairly average lot, with about 10-15% server power supplies included which don’t have any wires.
This is my result: Total weight before cutting the wires was 1370 lbs. It yielded 1220 lbs power supplies without wires, and 150 lbs of wire. It took a good two hours to cut, using a band saw. In my case it is well worth it, and I will be cutting the wires from now on.
