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.
It depends on what you mean by struggling but you can get pretty far with an 8th or 9th gen i5 and 16gb of RAM, would be a pretty cheap upgrade these days. The huge jump in quality for QuisckSync was between the 7th and 8th gen from what I remember so it doesn’t have to be new. If you are worried about power I think that it’s 65 or 70w for the 8th gen ones.
For what it’s worth, my current Plex machine is an 8500k with 32 gb of memory and a 250w power supply since it doesn’t have local storage and it has been running 24x7 for about 4 or so years now. I once load tested it for fun and I was able to do 7 or 8 4k transcodes and it wasn’t really its limit, I have no complaints haha.
