Dell validated this PC model with these CPUs: They only list a 460W PSU in the specs, so I assume it's adequate for any of the listed CPUs. Have you looked at any threads about upgrading the CPU in this PC model to see what CPU upgrades worked and/or if they needed to upgrade the PSU?
Greetings! I have slowly been upgrading my Inspiron 5675, service tag  .  I've got the Ram maxed out at 32GB, have a new faster 500GB SSD, and for my needs the Radeon RX 570 is more than adequate. The one thing I had always intended on upgrading was the Processor, which is currently a Ryzen 5 1400. I understand can be upgraded to a 1st Gen Ryzen 7 1700X or 1800X. My 5675 came with the 460W D460AM-03 Dell P/N OGJXN1 non-modular power supply.  My first question is, will this have enough power with the 1700X or 1800X, which draw 95W compared to the 65W of the Ryzen 5 1400? I checked out some PSU calculators, and they say 460W would be somewhat borderline with the specs of the system. 2nd question would be whether a standard PSU is compatibile with the ATX connector on the mainboard if I need to upgrade. Thanks for any help you can give!
