CPU Recommendations for Low Power System

[thomas-hn]

Hello,

my current system runs PVE with 7 VMs and 4 LXCs on a Intel Core i5-4690S @ 3.2 GHz with a CPU load of around 40% over all 4 cores.
I am planning a new system which shall be a bit faster but also consuming less power.
The system shall have ECC RAM and my preferred CPU would be a Xeon or another low-power server level CPU.

Do you have any recommendations for CPUs?

Thanks,

Thomas

Problem is more the chipset and mainboard and less the CPU. The more IO and features it got, the higher the idle consumption will be. But with 40% load I wouldn't call that idling.
