The 7050 isn't much for GPU upgrades, especially on a 240w PSU. From the Optiplex 7050 Spec Sheet:  Supports optional discrete graphics Tower/Small Form Factor: AMD Radeon™ R5 430 1GB/2GB, AMD Radeon™ R7 450 4GB Another option is the 30w GT 1030. GTX 1650 tdp = 75w, so I can't recommend it on a 240w PSU.  There are a lot of users on user benchmark using the GTX 1650 with the 7050, but it doesn't say with what PSU.  The same for higher watt cards listed on it.  [URL]  So hopefully I gave you enough info to make an informed decision.
