EVGA Nvidia GTX950 2GB OC

Seller Note: “seller note: Was working until I changed my power supply, now fan spins for few seconds then stops, no output. I tried with old power supply but still the same”

Suspected Issues:

  • Excellent general condition / clean
  • Sounded like a possible short.


  • After testing resistances, nothing abnormal was spotted.
  • Power on testing, shows a working card!
  • The fan is temperature dependent, I would say it could do with cutting in sooner (need to test more extensively)
  • Runs a little hot, hopefully new thermal paste is all thats needed before more benchmarking.

Next Steps:

  • Need to improve thermals before I would be happy to sell this card.


Since card is working (pending more stress tests), there isn’t a great deal to report.

TODO Complete/correct this section anyway in case of similar cards in future and maybe help others.
