There's a table of compatible CPUs in the G5 5090 Setup Guide. What size PSU do you have now: 360W, 450W, 500W? The PSU in this model is customized and can't be upgraded. The larger PSU versions may not be available as a "spare part" from Dell. You probably will need a better heat sink and bigger fan(s) if you get any "K" or i9 CPU which use 95W vs the other CPUs at 65W. Lots of threads about upgrading/adding new fans and better heat sinks in the 5090, so search for them.
Hello there, I have a Dell G5 5090 Gaming PC that came with an Intel Core i5-9400 CPU @ 2.90GHz. I am interested in upgrading to a better processer, but am not sure what will be PNP compatible. I would also like to know if I would need to upgrade the factory-supplied power supply or the factory CPU cooler. Thank you for your time.
G5 cpu upgrade?
