I saw some people talk about power consumption and being higher on Unraid. I wanted to show some examples I've been gleaning from my 2990WX system I've build. First configuration..

AMD Threadripper 2 2990WX - PDO OFF

64 GB G.SKill 3200 CL15 RAM - OC'd to 2933mhz(Fastest I can get with this board)

ASUS X399 Zenith Board

16 8TB WD Reds

2 10 TB WD Reds - Not part of the array  yet.. Adding another 3 10TB WD Reds before I start adding.

1 Samsung NVME 960 512GB

1 Intel 240GB SSD

1 Sandisk 960GB SSD

EGVA SC2 1080Ti

1600w Titanium PSU

Enemax TRII(I know you don't have to tell me) 3x120MM fans

5x 140MM Fans

1x 120MM Case Fan

 

All measurements are taking from the UPS

 

1. Idle Consumption - All VMs off, All Drives Spun Down, Plex & Such but no trans-codes occurring Dockers running(allocated 8 cores) On-Demand

 

2. Online Consumption - Drives Spun up, Gaming VM Running - Chrome Running, Discord, few other apps CPU utilization below 10%

 

3. Online Consumption - Drives Spun up, Gaming VM Running Game Running - Satisfactory - Medium Sized Factory - CPU Utilization in VM at 40%

 

4. Online Consumption - Drives Spun Down Gaming VM Running just like #2

 

 

I believe the bulk of power consumption comes from the VMs themselves. The Windows 10 VM is fully patched but do not appear to "idle" like I would expect when I log out. I can save a lot more power by simply turning the machine off at night. The only PIA with that is I have to turn the VM back on in the morning when I come in. By doing that I can save over double the power. I've also been reading there are tweaks you can do the XML but I've done most of them. Below is what my XML looks like that does appear to have lowered idle consumption but just not as much as I would hope tbh. I kind of wonder if the GPU isn't going into lower power mode or something as well.

 

Anyways just thought I might open discussions about power consumption. Its always an interesting topic and I assume most if not all of us run our servers near 24x7.

EDIT:

 

Turning down refresh rate to 60hz substantially lowered power consumption

 

#5. All disk Spun up just like Example #2 but with 60hz set and gsync off

For comparison this is my typical power consumption:

 

One Unraid Server with Xeon E3-1220v5, 15 HDDs, 1 NVMe running 3 Windows VMs (no GPU).

One Unraid Server with G4560, 8 HDDs, 12 SSDs

24port Gigabit Swith

Wireless Router

All disks are always spun up, but most are 2.5".
