value of computer power supplies

Has anyone sold many computer power supplies from taken apart desktops. I used to take them apart for the little copper and alum. I've put a couple of 400+ watt ones on eBay and sold them. My question is this: are those with more wattage tend to sell better than low-powered ones? Or does it depend more on a specific brand/type of a supply? So far I've been discarding those that are less than 300 watt thinking that they are not worth my time trying to sell them. Am I wrong?

Thanks

why don't you check completed listings on Ebay? that will tell you all you need to know, brand, watts, price, etc, etc, etc.

good luck

I was hoping to pick other people's brains to help me make a quick "sell or scrap" decision when I pull out a PS when I take apart a desktop. So clearly I can check each one on eBay but I was wondering if there are any quick rules of thumb. So thanks for the info on Cooler Master.

so do i get better money for whole power supplies or if I break them down?

Run the model numbers on Ebay look at volume completed over time on listings for said model number. IF there is only a few listed and a steady sale track record throw it up there. OEM replacement s and some proprietary PSU's do quite well on EBAY. Do yourself a favor and pickup a tester and make sure you are getting good voltages across all rails before listing or you will be getting it back. Good Luck!

Anything that is under 400w I don't even bother with listing on ebay. Most newer computers need at least 400+w power supply. The only exception would be for vintage computers. Personally i'm getting to the point where i don't even break them down anymore. Like Mechanic said there are buyers on here for them, but you might be better off finding a yard that buys them. You'll get a lower price, but with shipping it's not worth it unless you have a ton of them.

One last note on this. I have been told that the power supplies that have an in plug and an out plug are illegal to sell as they are a fire hazard.[/QUOTE]

Is this true? I had a search for it & can't find any info about it at all. I have been saving the 'out plugs' (fixed sockets? FWOABN) for a while thinking they would be handy to put into stuff.
Like to retrofit a plug on my welder so I can run a anglegrinder directly from my welder. Then I only need one power cord to the welder & another leaves the welder to the grinder.
Theres better ideas to explain what I want to do though.though

I don't sell anything on fleebay so I brake down all my power supplies and get .40# for the boards and 1.05 for the wires and .09# for the steel. Only you will know if it is worth it or not.

Newby; I throw the fans in with my motors and get .36# for electric motors. But I have to have 500# or more to get that price.

i use a bypass pruning clipper
Amazon.com: Felco F-2 Classic Manual Hand Pruner: Patio, Lawn & Garden
cuts all the wires at once right at the box.
i get .30/lb no wires,.40w/wires. if i take the board out of the box it is low grade @.10/lb steel@.08.
about once a month i clean out the file cabinet that they are all stacked in and take them in.
the wire is usually atleast .6lb @1.02/lb so each one is roughly $.60-.30 for the grading reduction.

I'd look for AMP ratings on those plugs, they might be a bit weak for grinders and welders


As far as power supply values go, not using Ebay, my only options here are tear them down or sell as shred

I started breaking down my power supplies and think it is worth doing considering some of the things inside are worth more per lb than power supplies with out wires

I agree on finding a computer person to trade with. I work on computers and many times folks like myself tinker on them at home. I know a lot of guys who would trade you a pickup truck bed full of old computers for just a few good usable power supplies. One thing is if they do not recycle themselves in my area its hard to get rid of the volume we might see. I have been given truckloads of junk just to haul it off. Save the newer stuff like the sata stuff. Ask them what they might need as well. Those 20 computers a office gave you might be worth 20,30 or more each to the right person. I have on more than one occasion gave a truckload away to a person for just coming and getting it.

It sure would be nice to have someone trade a load of old computers for some good parts.
