    Pictures/Weights/Prices of a Powersupply (to break down or not)

    I have.... quite a few of these, and already broke down about half of them. But it took a while and was becoming tedious so I decided to do a break down and calculate out if its worth it to continue to do these with what I feel is an "average" power supply.


    So here are some combinations/options and what they yeild, per power supply.

    • Total weight before disassembling: 2lb1.7oz
    • wires (snipped off without disassembly): 0lb4.8oz
    • misc steel/shred: 0lb14.5oz
    • wires from inside, snipped after disasembly: 0lb0.7oz
    • lowgrade board after removing stuff: 0lb5.9oz
    • alum heatsink: 0lb2.6oz
    • transformers: 0lb4.6oz


    Options:



    • Sell complete w/wire (would need to be online as do not have a local ps buyer)
      • Whole psu: $0.24/lb == $0.5055 (less shipping cost)

    • Snip wire, Sell as wire local + ps w/o wire online
      • PSU, snipped wires == $0.18/lb * 1.80625lb == $0.325
      • Wires == $0.40/lb * 0.3lb == $0.12
      • Total: $0.445

    • Snip wire, sell whole rest of PSU local as shred to avoid shipping and disassembly
      • Wires == $0.40/lb * 0.3lb == $0.12
      • PSU, snipped wires == $0.04/lb * 1.80625lb == $0.07225
      • Total: $0.19225

    • Fully disassemble, sell all local at local prices
      • Wires == $0.40/lb * (0.3lb + 0.04375lb) == $0.15
      • misc steel == $0.04 * 0.90625lb = $0.03625
      • low-grade board == $0.05 * 1.36875lb == $0.0684375
      • alum heatsink == $0.21 * 0.1625lb == $0.032125
      • transformer == $0.08 * 0.2875lb == $0.023
      • Total: $0.3098125 == $0.31

    So, in summary,
    I could get $0.51/unit mailing them off and not disassembling/touching them at all, but have to subtract out shipping.
    I could snip the cords, and sell the PSU online to someone here, for $0.45/unit, but again, still have to pay shipping for those.
    I could snip the wires, and throw the PSU as is in the shred pile, avoiding all shipping, for $0.19/unit
    I could do what I have been doing, fully taking apart and selling all bits locally to yards, for $0.31/unit, avoiding all shipping, but takes forever.


    Not really sure that makes it any clearer what the best option is.... but.... that the info I have now.
