I have an H11SSL-i with EPYC 7232p, 128GB of DDR4 ECC DRAM, 2 1TB NVMe drives, 3 3.84TB SATA SSDs, 1 6TB SATA EXOS spinner, and various other minor things. Idle consumption for the entire system is under 80W.

I don't think the OP, @graczunia, is specifically sweating 100w. That came into the discussion later. Reading their post, I think their main question was, could they replace a dual E5 v2 system with something newer and get both more compute and more efficiency? They specifically mention Scalable and Epyc but mention they are open to other ideas.IMO if you're sweating 100 watts Epyc and Xeon SP might not be the best route.
Maybe look to upgrading the Xeons? I have a dual 2696 v3 setup that peaks at 370w with 8x8gb DDR3 installed so DDR4 should be lower power still. RAM type and quantity makes a difference here too. I use it when I have a bucket of threads I need to throw at something and not huge IPC.
Saw another post of yours in another thread and remembered that I wanted to treply to a certain postis not idle
idle(not sleep / power saving):
- unemployed,
- unoccupied,
- free to start a job
no bios tuning Im guessing?h12ssl, 7443p, 128gb ram, 17x 16tb hdds in a sm 846 with sas expander backplane and raid controller: idle ~190 watt* (windows server 2022 login screen, large movie file being read from the array)
*measured via ups: system under load - system was powerded off
@graczunia how do you define "idle"?
I do have a spare ASUS Z10PE-D16 WS, might play around with it and see how it goes - would fit perfectly in my Supermicro chassis.IMO if you're sweating 100 watts Epyc and Xeon SP might not be the best route.

For the sake of the argument let's assume system is booted into Proxmox with a TrueNAS VM running, no reads/writes on the disks/network activity.@graczunia how do you define "idle"?
Spot on - I'm looking for a replacement for the powerhog that the dual E5 v2 system is; not really considering how to reduce it's power draw as it doesn't seem to be worth the effort. Something that is more 'worthy' to run 24/7 on a student budget for a lack of better wordI don't think the OP, @graczunia, is specifically sweating 100w. That came into the discussion later.

Since Sandy/Ivy Bridge are a dead end upgrade wise, a system upgrade is going to require replacing motherbaord, CPU, and RAM. @graczunia , I'm not sure if your main criteria is reducing consumption or replacing a system that's on an almost 10 year old platform?
Reading everyone's replies, the consensus (which I agree with) is that it's going to be the disks, HBA(s) , 10G networking, maybe PSUs if they are innefficient, and everyting else that's attached, that drive the higher consumption. If you replace a dual E5-26xx V2 motherboard and CPUs with a single early generation Scalable or EPYC, but transfer over/reuse your other components with the same general configuration, you may get more compute/easier management, but it won't save you much powerwise.
There also seems to be a consensus that, for the early generations, EPYC drew more power. I don't have either one, so can't comment on that.
Since you'll need Motherboard, CPU and RAM as a minimum, the 500 euro budget for the base components is going to be tight. You'll get newer, but not much better in the efficiency area.
