Help with an energy efficiency overhaul in Hardware Posted April 15 · Edited April 15 by charle_bouq_123 I've got an existing build that's extremely power hungry. Can anyone offer advice on the easiest way to make it more efficient? The primary use-case has been occasional file backups and 2-3 Plex streams that are usually 1080p -> 720p transcodes, but I want to be able to do more 4K -> 1080p transcodes. The system is completely overpowered now. Current build: CASE: Rosewill 4U server case CPU: Dual Xeon E5-2670 PS: 1100w gold power supply that came with Thinkstation D30 MB: Thinkstation D30 (it's a massive board that's bigger than an EATX) GPU: Quadro P2000 RAM: 64gb ECC HDs: 12TB parity, 4x 10TB data, 2x 1TB SSD cache Current idle power is about 150 watts (!) and with a few transcodes it can spike to 200 watts. How do I make this more efficient? I want to get it down to 40 watts idle, even 60 watts would be great. Do I swap out CPUs? I'm guessing that would bring it down to 80-100w idle? Do I swap out the motherboard, power supply, CPU, and RAM? I'd be fine shelling out $400 or so, but is that just a plug-and-play operation or do I have to rebuild my Unraid entirely? Thanks for your help!
