[Build Upgrade] I want to make my current computer as power efficient as possible without sacrificing too much power. What is the best way to do this?

My computer currently pulls about 90w-100w at idle and close to 400w when maxed out. I want to lower it, if possible to about 50w idle and 200w-250w maxed out.

Specs for my Current PC. Along with these I have 3x 230mm fans and 2x 140mm fans installed (4 came with the Thor)

Even though it is just an upgrade I figured I would fill this out anyway just to give you all more information.

What is your intended use for this build? The more details the better.

Daily use/work, Plex Server, video transcoding, some gaming

If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)

I am not as strict on this as I used to be. I have 3 1440p monitors but would be fine even playing on 720p since I usually use my Steam Link to play on my TV. I only really play Skyrim, Minecraft, and City Skylines, but occasionally I will play larger titled games that come out (still want to play The Witcher 3 & FO4). Playing at 720p with medium graphics doesn't matter to me as much as frame rate, but being able to play at 1080p or 1440p is a plus since I am used to that.

What is your budget (ballpark is okay)?

Have not set a budget but if a new build is required for what I want I would rather not spend more than $600

In what country are you purchasing your parts?

USA

What I am deciding between. My goal is to try and keep the wattage as low as possible.

I have been looking at replacing my CPU with an E3 1230L v3/E3 1240L v3 (25w TDP) and get a GTX 1050/1050ti/1060. Or I also have been looking at building a new computer with the i7 7700T or E3-1240L v5 ($165 on ebay) with a GTX 1050/1050ti/1060.

One other option I have been considering is to buy a Skull Cannon Nuc or Mac Mini and get an eGPU so I can just plug it in when I need it. Or ust get a regular NUC/Brix with Iris Graphics. I do have both a PS4 and Xbox One I could start using more for when I do need to game if I just got a NUC/Brix, but I prefer PC gaming to console gaming.

In addition to the above options, if I was to keep most of my PC what would I be able to do to make my computer more power efficient? Remove most of the fans? Get a Platinum rated PSU? Get a lower end mobo?

Any and all advice and opinions are greatly appreciated!

Thanks in advance!
