I'm looking to upgrade my Plex and game server. I currently have an i5-4690K with 16 GB DDR3 and it's struggling a lot. My PSU is a 850W gold rated EVGA from 2017 so I don't think it needs upgraded quite yet since I've been way under the wattage for most of its life.
I was looking at something like a 13400 but I'm not sure if it's the best choice or what to pair it with.
Intel's not good for power efficiency. Id recommend any old entry level b550 AM4 motherboard, drop a ryzen 5600x in it, buy 32 gigs of dirt cheap DDR4. You'll be out the door $250 and be in amazing shape using half the power of Intel's hungry 13th gen 14nm+++++++++. If you wanna spend a little more get a 5800x for 2 more cores. It'll handle all your server stuff no sweat.
