Here is a 300W Dell OEM psu compatible with Inspiron 3471/3470 and optiplex 3060/3050.  DP/N J82T5  [URL]
Hello everyone, I bought myself an Inspiron 3471 last year and I'm looking to upgrade the PSU in order to add a better GPU. I search almost everywhere on this forum and on Google but I didn't find the info I needed. I was wondering if someone knows if there is any other Dell's models that uses a PSU with the same dimensions and connector?  I just need something around 300-350W rather than 200W. It would be realllly appreciated! Thanks!
