This forum thread has more information and I believe the 7050 and 7060 use the same 130W adapater.
Hello,I bought Dell Optiplex 7060 Micro without a power adapter. My CPU (i5-8500) is capped/stuck at 800Mhz.   I'd like to know what is the correct power adapter model originally supplied with Dell Optiplex 7060 130W.   Thank you.
