Some things I have picked up from my attempts to reduce the power consumption of my homelab: 1. AMD has processors with G and GE suffix that have greatly reduced TDP and have an integrated GPU. Combine that with an ASRock board with IPMI and ECC RAM and you have a great, low cost, low power base for a homelab server. 2. 10GBE over copper takes a lot of power. If you use SFP+ you have the option to use multimode fibre instead, that usually is lower power AND lower latency. 3. Standby mode for HDDs in a NAS was shunned in the past as it had a negative impact on the longevity of the drives. Modern HDDs however are much more resilient and can tolerate much higher power cycle counts. An inbetween on Truenas is Adv. Power Management that can be set to low power states without spindown. 4. Shuting down unused VMs has a measurable impact on my server. A Win 10 Pro on my system uses 5-7 Watts. Containers tend to use less power, as they use the OS infrastructure of the host. 5. Don't assume, measure. I used some cheap power meters with tasmota to stay on top of my homelab and check the impact of changes on power consumption.

love the timing of this video - over the last 90 days, I've been doing efficiency changes to my homelab, dropping my overall kW commit from 2kW/m to 0.4-0.6kW/m, obviously I did this with money lol but getting rid of very old hardware for some new age 15-75kW servers is amazing. 10th-13th gen infrastructure offers such robust performance packed into tiny packages of power. When it comes to shutting down servers, I try to get things to sleep where I can and yes, WOL is great to instantly wake and resume these servers - unfortunately a lot of users are intimidated by the issues of sleep (automatic wakeup, GPU performance failure, windows poor compatibility since windows7) which is why I think it's not used as much as it can be but is very useful for a desktop PC with high wattage that gets usage randomly throughout the day, sleeping can save atleast 0.2kW/h for my 13th gen i9, that probably doubles or triples for the AMD users. Totally agree with you man, great video.

I'm in the process of revamping my little home setup and have been working on exactly this. Smart plugs + home assistant (or another logging/monitor app) to monitor power usage has been helpful until I grab some UPS's to figure out how much power I was using where. Also swapped out some older systems with really low power mini pc's where I could (opnsense for instance). Hardest thing has been upgrading my NAS to keep it relatively low power and keep all the features I want but that's probably the last thing I'm going to upgrade so I have time to decide on that one. Only leaves 1 power hungry Epyc server but I'm not getting rid of that one! Funny thing is overall swapping the lightbulbs to LED, replacing some old appliances and turning off idle audio equipment (sub/amp) saved me more power overall but my homelab isn't very big.

As others have said in the comments, set up energy usage monitoring. If you absolutely have to, you can report usage in units of Raspberry Pi, but it's optional. You can find the advertised energy consumption of components before you buy or install them. If you decide to install them, please check your own measurements (discrepancies can be configuration options and are not always bad faith marketing). Home automation components can help shut down containers, VMS, servers, etc., when not in use and be sure startup and shutdown work flawlessly while you save power. Run components in the public cloud where sensible; the hyperscalers are putting a lot of effort into reducing power usage and we can make use of that while adding some "hybrid cloud" to our home labs.

On my primary server I ended up having some simple cronjobs to automatically switch cpu governor between schedutil and powersave depending on the time of day. To be more specific, electricity at night is slightly cheaper here, so I run it as schedutil (default) during the night and powersave during the day. This will cause the cpu to basically stay at the lowest frequency, but for my workload that's fine. Some cpu heavy tasks just take slightly longer. In my grafana dashboard where I see the wattage used by this server through the PDU I can see exactly where this script triggers every day.

One thing that I don't see enough coverage about: LXC Containers. Especially if you run Proxmox, using LXCs instead of full VMs saves quite some resources. You can still run stuff like Docker and if you don't need hardware passthrough. Also these containers start a lot quicker than some VMs. Basically anything that doesn't require Windows runs as an LXC in my homelab, and I run these on a cluster of 2 NUCs with 1TB NVMe SSDs and 64GB RAM each. The only power-guzler at this time is my Storage server, which is an enterprise-grade 1U server with 4 HDD bays, which sits at around 90W. But everything I store is on that NAS, so I don't see a reasonable way to turn it off at night or something.

Good video! I built a TrueNAS scale machine last years with a HDD pool and a SSD pool, thinking I could make the HDDs go to sleep when I'm not making backups or watching some video. I practice, they wake up too often for it to make a real difference, while lowering the lifetime of the disks. Also, getting a server board with features like IPMI was cool, it it consumes around 8W even when everything else is off. So 8W on top of whatever the server uses to do useful stuff.

My backups run in the night, so powering down is not an option. Also starting up and shutting down would cause a lot of wear and tear on the system. I have my main Proxmox running on a desktop MB with 64GB of RAM and Ryzen 5950X CPU and a 2nd Proxmox system running on a older Micro HP G3 800 computer. My backup NAS is powered by an Atom based MB also running TrueNAS. I lastly have another TrueNAS system which is my off-line archive. It get connected to power and network only when I backup to it and then turned off and disconnected. Will have to look into what settings I can tweak on my NAS system to save some power. Besides all the regular data on the NAS, I have my movies, TV show and music collection. Would love to have SSDs instead, but the sizes I require are not available yet and even if they were, I could not afford it.

That’s exactly what I’m using on my phone ☺️

My first home lab was on the 1950x thread ripper.. When it was new.. Yes. I vowed never again, so I have a few extra tips. Use old gaming LAPTOPS if you need a gpu. Way more efficient and bonus ups. The m.2 ports can act as pci express ports btw. Power supplies use more power than you would expect. If your going for efficiency look into a pico psu. Otherwise do your research Along the same vein, aliexpress router boards are awesome. I have one with 4 2.5g ethernet ports and a pci express port. I virtualise my router and one of my nas here. While using a pico psu because I use ssd. Along with what Christian said, inbuilt on motherboard is more efficient then addon cards. SSD ARE MORE EffICIENT THAN SPINNING RUST. Containerise everything, or if you can't Virtualise everything... Including your gaming PC. It is 100 percent possible. (I used to virtualise windows for this, but these days I virtualise a Linux gaming vm... It's more efficient). Don't put your router and gaming PC on the same hypervisor though 😅, learned that the hard way. A Raspberry Pi with a ethernet port is all you need to automate the power for these 😁. Finally, find a way to automate turning off the power at your home.. A managed powerboard.. Or a ups.. Or even add automation to your switchboard. That way you can turn everything you need off when you aren't home.. It will literally save you thousands.

how do people recommend c series chipsets for "cheap and has ecc" when all used boards are neither c236/c246 boards start at $300-400 and come with standard ddr4 slots and apparently ecc modules that would fit in there just don't exist

Dont use ECC and your life will be a lot easier

my TrueNas server consumes approx. 20W more with a 10Gbit card than without... that's almost 50% of the idel consumption.

Saved 150 watt per hour by using hdparm for my HDDs. Use command hdparm -y and ps aux | grep hd-idle | grep -v grep | cut -c 66- ; for f in [a-d] ; do hdparm -C /dev/sd$f | grep -v "^$" ; done command to check the state. Saved me over 30% power consumption. This box has several HDDs that only being used a few times per week. The run ProxMox v8.

buying older commercial hardware is useless in uk overpriced by so called green recycle buisnesses,not only cpu power matters big fans other board power uses ipmi and others even off still consumes 10-15w
