How to Recycle Mining Power Supply Units (PSUs)
High-wattage ATX, server, and miner-branded power supplies (roughly 1000W–3000W+) used in crypto mining. Copper, steel, boards, and large capacitors. Intact recycling only; do not open the chassis.
Quick answer
Mining and server PSUs recycle as electronics. Unplug, leave the case closed (capacitors can hold a shock hazard), separate any UPS batteries, then use a municipal or certified e-waste recycler. Best Buy lists UPS units more clearly than bare PSUs, so call ahead. Resell working known-brand units when you can.
- Recyclable
- Yes
- Typical value
- Working server and 80 Plus Gold/Platinum ATX units often sell used. Breakout boards for server PSUs sell separately in mining communities. Dead units are scrap-metal/e-scrap value only.
- Donate / take-back
- Available
- 1Unplug from the wall and from miners or GPUs
- 2Wait several minutes before handling connectors; leave the case closed
- 3Separate any UPS or external battery packs for battery recycling
- 4Coil cords and tape loose connectors for transport
- 5Note brand, wattage, and 80 Plus rating if you plan to sell
- 6Do not attempt DIY capacitor discharge with a screwdriver
- Municipal e-waste collection and certified R2 / e-Stewards recyclers
- Computer recyclers and ITAD firms (bulk farm PSUs)
- Best Buy (call first for bare PSUs; UPS units are listed)
- Staples (ask; better fit for small computer gear than industrial PSUs)
- Local PC shops that buy working high-wattage units
High-voltage capacitors can retain a dangerous charge after unplug. Recyclers take intact units. Best Buy's published list emphasizes UPS and surge protectors more than bare PC power supplies; confirm before you drive over. Staples accepts computers and small servers; large industrial supplies may be refused. Failed, burnt, or swollen units go to e-waste, not backyard repair.
PSUs contain copper windings, steel, aluminum heatsinks, and circuit boards with lead solder. Keeping them in the e-waste stream recovers metal and avoids dumping capacitors and boards in household trash. Extending life through resale of working units cuts demand for new power supplies.
- Resell working branded PSUs to PC builders or miners
- Reuse in a high-power workstation or lab bench (if specs and connectors fit)
- Sell modular cable kits separately when demand exists
- Recycle failed or no-name supplies intact
- Standard PSUs do not store user files
- Remove asset tags or labels with personal or company info if needed
Accepted
- Server PSUs used for mining (HP, Dell, Delta, and similar)
- High-wattage ATX PSUs (1000W+)
- Miner-branded supplies (for example Bitmain APW-series)
- Modular cables accompanying the unit
- Non-working units for e-scrap (intact)
Not Accepted
- Opened chassis with exposed internals for casual drop-off
- UPS batteries left attached without calling them out for battery handling
- Fire-damaged units mixed into trash
- Curbside recycling carts
Estimated value: Working server and 80 Plus Gold/Platinum ATX units often sell used. Breakout boards for server PSUs sell separately in mining communities. Dead units are scrap-metal/e-scrap value only.
Donation
- Computer refurbishers and vocational electronics programs (working units)
Manufacturer/Retail Take‑Back
- High-voltage capacitors that can hold charge after unplug
- Lead solder on circuit boards
- Brominated flame retardants in some housings
- Lithium-ion or sealed lead-acid batteries in companion UPS units
Is it safe to open a PSU before recycling?
No. Capacitors can deliver a serious shock even after unplug. Leave the case closed and let the recycler process it.
Will Best Buy take my Antminer power supply?
Unclear. Best Buy lists UPS and surge protectors more clearly than bare mining PSUs. Call the store. A municipal or R2 recycler is the reliable path.
Can I sell a used 2000W mining PSU?
Often yes if it is a known brand or server model, tests clean, and includes cables or a breakout board buyers need. No-name burnt units should go to e-waste.
Do PSUs contain batteries?
The PSU itself usually does not. The UPS next to it might (lithium or lead-acid). Recycle batteries through a battery program, not as scrap metal.
Are mining PSUs worn out from 24/7 use?
Not automatically. Steady load can be easier on quality supplies than constant on/off cycling. Check for bulging capacitors, burnt smell, loud bearings, and voltage stability before reuse or sale.
What about Corsair or EVGA take-back?
Do not assume a free nationwide mail-back. Corsair has advertised a take-back channel; confirm by phone before relying on it. EVGA consumer take-back was not verified for this guide.
