Ewaste Scrapping - Make the Most Money on Computer Power Supplies

Shark Scrapper is scrapping more ewaste for value comparisons. This time we look at how to make the most money from computer power supplies. Should you sell as is, scrap for the wire and boards OR micro-scrap the components, copper and aluminum off the low grade boards?

Very thorough comparison, Professor Shark!! It's always so easy just to tell someone "It's not worth the time", but to actually SHOW them why makes all the difference. And as you said, there are differences from yard to yard. I have found a place that takes low grade boards for $.38/lb. I get $.18/lb on transformers, so I don't strip the transformers from the boards anymore.

[@sharkscrapper]

It's amazing how the prices can vary and so important to understand the math behind one's decision. Spot on man!

Hey Roger. It get 15 cents a boars. Boo! Everything except low grade board that are depoped will be going to my yard.

[@jackpalczynski7884]

How your scrap yard categorizes things matters a ton. That wire with connectors, you called copper 2 at over $1 a pound. I just brought essentially the same thing to my scrap yard and they call it ribbon cable at 45 cents a pound with or without connectors. Connector ends and small transformers and inductors are all considered steel and they pay 6 cents a pound. So it's very much worth knowing what YOUR scrapyard categorizes it and what they pay.

[@sharkscrapper]

Very, very true. Thank you for sharing that very stark difference.

Very well demonstrated and your right for me personally I am disabled. So I do this just for something to keep busy and have something I can do. Therefore as you said for those like me time really has no value as the point is just keeping busy and make as much as possible from every item we scrap. I have no place local to sell boards so I strip all components and collect them till I have enough to further process and recover the metals. Even after boards are strip the plain board has copper, silver, lead and occasionally even some gold tracing.

This is the best scrapper channel I've found so far! Kudos! You got yourself a subscriber. I just do a little scrapping for fun, and I don't do anything on PSUs. I don't even collect them if I don't find them already dismounted from the case. Being a hobbyist makes me even more selective on what I spend my time on. The low yielding materials only make sense, if you bring significant amounts to the yard. Like >100kg. I don't want to plug my small home shop with such storage of junk.

[@cobrawearer]

Love all the math, I would love to see the average hourly/step break down. Because one would not skip to the last few steps without doing the ones previous. I see the more time spent equals less per hour made, but if you average the first step with any of the other steps, the hourly comparison would look more appealing.

Those times were factored in.

[@dr.a006]

Thanks for taking the time to compare the levels of microscrapping. Of course I do this all is my spare time when I’m not doing a million other things. When you have huge volumes of scrap, the more efficient the better. When it’s sparse, then you make the most of what you got. Either way, I definitely won’t quit my day job! 👍

25 years in the Navy taught me a little about organization - that and a few years scrapping out of my garage. It's tough but doable. The key is to NOT let things build up. It's hard to stockpile unless you live somewhere where you can store thing outside. Even then you need to keep it neat and protected from the weather.

I always pull all the copper. Including the brass from the prongs in the plugs and the ends on the cables. It takes me an avg of 15 minutes per supply using all manual tools. I would get just shred prices for the supplies, which is about $65 a ton, as no yard in my area would pay power supply prices. I also have a pile of fans that I hope to sell as fans. They are used in a lot of projects and art. I also have no local places to send the boards and they just go as breakage online. I am also saving capacitors in hopes of finding an easy way of cleaning them up for the aluminum.

[@sharkscrapper]

Your comment is a great example of how important it is to understand how to maximize your return based on what your local yards take and pay. Keep up the great work.

[@ScrapFatherScrapSon]

The only thing I would suggest is get a pair of craftsman aviation snips with the long nose. That way you can snap through those wires and one swoop, save even more time. Awesome video I made a video the other day asking if I should cut the wires off of the power supplies or do I need to leave them on to get the price

[@sharkscrapper]

By now you know it really comes down to what your yard will buy and how much they pay for each category. Don't be afraid to ask them either on the phone or when you're there. The good yards are happy to help you understand how to sell to them. If they don't want to answer your questions, find another yard.

[@josephcormier5974]

So micro scrapping is the way to go for the long run. But when you're flat out then snip and toss. Great video very informative well done two thumbs

It all comes down to how you want to spend your time...kinda pretty much like anything 🤣

[@markmatt9174]

Scrapped on & off over the years, best thing for old powers supplies is reuse, turned a few of the into benchtop power outlets, they have multiple DC voltages great for a electrical supply on a work bench. 👍 3.3 v, 5v, 12v, & often -5 & -12v. And 24v across the -12 and +12v. 😊 Most of them needs a small jumper to run if not hooked to a motherboard. Lots of videos on how to make them work outside of a pc.

[@sharkscrapper]

It's always good when you can reuse/repurpose for sure. Of course, I go through 50 or more a week so scrapping is the way to go for me.

[@karlan3016]

This is the video I’ve been looking for !! Thank you much. I’m a relatively new hobbyist. It feels good to take apart and recycle some of these electronics that the tech world keeps leaving behind so quickly for the newest model, the newest features, etc. Looking forward to watching more of your videos - I want to be efficient! Can you tell me what type of drill bit you use on the Dewalt driver ? The long black thin one? Is it like a universal bit ? So many of these electronics have all different screws, hex screws, etc. i spend wayyyy too much time trying to find the right bit and it seems like jt saves you a lot of time to use that same bit on (most) or the screws in the boards and outer casing.

[@sharkscrapper]

Unfortunately, there's no getting around changing bits. I've been using a 4' long flex head PH1 lately (available through my Amazon link). But I still need to switch to a torx, especially for HP products. The other frustrating thing is some electronics are made with the Japanese standard Phillips screw. It's just different enough to make it difficult for a worn screw bit. I keep a couple different hand screw drivers at the ready just in case.

Thank you Mick - I'm glad you found it useful. AND...welcome to the channel, it's great to have you here. Scrapping ewaste is on of those areas where there are few "wrong" ways to do it. Obviously, burning wire or dumping heavy metal laden acid waste is in the wrong way to do it category. But questions such as what to break down, what to depopulate, etc, are so dependent on each scrappers situation: how much time you have, prices at your yards, biz vs hobby, and the list goes on. I'm always mindful of this when I make the comparison videos and try to present the information in such a way that each scrapper can make a better informed decision for what will work for them.

(ReUse is still best) But some of them will be taken apart completely one night come winter - just to see what's inside. Cheers*

[@sharkscrapper]

LOL at version D. Yes, reuse is still best use. I should have mentioned that some of the newer power supplies do resell but they need to be on good condition. The higher the wattage the more likely someone will purchase it - again if in good condition and functioning.

It’s best to also know the weight of your scrap and some yards only pay by the pound and anything less you get nothing so know who your dealing with and do the math!

[@sharkscrapper]

Most of the larger deck scales measure in 1 pound increments just like my deck scale, so that's very normal. The big vehicle sized scales measure in 20 pound increments. It's very unusual for yards to measure in finer increments, except for some that specialize in e-scrap like Boardsort.com.

Power supply wire isn't #2 wire, even with the plugs removed. A large amount of power supply wire is actually insulated aluminum wire.

[@sharkscrapper]

At the non-ferrous yard that buys my scrap it is Insulated Coper Wire #2. With so many differences in how yards classify and purchase materials we can't just say this is, or isn't, #2 wire. It is whatever our yards will pay us for. If your yard requires that you separate any aluminum wire that is mixed in the bundle from the copper wire, then that is what you must do.

Now all I need is a warehouse full of them 🤣😆

[@mariushmedias]

There's a few problems... your numbers are skewed because they're all different power supplies. If all were the same, you would strip them much faster, as you'd get into a routine and do them in batches .. stack them and unscrew them all in one shot, then cut the wires of all in one shot then remove fans of all in one go and so on. Your methods are also quite UNoptimized ... for example, I wouldn't use hand tool like pliers to cut the connectors off the cables, it takes too much time. I'd just use a paper guillotine or something that can be operated with a foot pedal .. for example, put the cable under the blade, press pedal and the blade goes down cutting the wires in one shot. If you collect enough cables, like for example a barrel, you could have something automated (like those wood splitter machines), a blade that rotates at a fixed rotation so you can just slide the cable into a channel and at next rotation the cables will be cut.

[@sharkscrapper]

What you are calling "problems" are the realities for most scrappers but, as you point out, are also opportunities for efficiency. Yes it would be faster to do all the same design PSU, but we rarely have all the same kind. Your suggestion to batch the process is a one of those never ending "Lean/Six Sigma" challenges that can only be answered with more time trials and analysis. Which could make for an interesting video some day. Certainly some form of automated cable cutting device would make removing the wire faster/easier but how many scrappers have or can afford such a device. I certainly appreciate your ideas and suggestions. In time I may be able to implement, or at least test some of them.

[@maryannrussell7255]

Did you forget to weigh the wire after you cut it off and include it in the final comparison?

[@sharkscrapper]

No it's included in each of the scenarios. You'll the a line for ICW #2 in the spread sheets. You'll see that in scenario C the weight is very similar to scenario A at 5.1 lbs BUT that is the weight of the weight of the wire with the ends cut off plus the weight of the wire from inside the power supplies.
