This machine can take any socket 1151 CPU from the 6th gen Core series or Xeon E3 12xx V5 families. The fastest for each are as follows: --Without integrated graphics--Xeon E3 1280 V5 (quad core with HT 3.7GHz / 4GHz boost [NAME]) --With integrated graphics--Core i7 6700K (quad core with HT 4GHz / 4.2GHz boost [NAME])Xeon E3 1275 V5 (quad core with HT 3.6GHz / 4GHz boost @[NAME])Core i7 6700 (quad core with HT 3.4GHz / 4GHz boost [NAME]) looks like Dell did a mid model refresh to add more CPU support and since yours is configured with an i5 7500, you should be able to use any Socket 1151 7th gen i7.  Here is your fastest option for each power consumption level: Core i7 7700K (quad core with HT 4.2GHz / 4.5GHz boost [NAME])Core i7 7700 (quad core with HT 3.6GHz / 4.2GHz boost [NAME])Core i7 7700T (quad core with HT 2.9GHz / 3.8GHz boost [NAME])
I currently have the T3620 with a i5 7500, I was hoping to upgrade this and was curious what the highest CPU this system can take? Also anyone changed the PSU also? Is is a standard ATX Psu?  Many Thanks C
