Ok, so here is my quick question, I think i know the answer but want to be sure.

TDP of a Xeon 2699v4 is 145w (I'm aware its not directly relational to power consumption, but websites like ExtremePSU calc use it as a reference... so putting it in here for reference)

This TH article has the system they are benching consuming about 500w of power, but as far as I can see it doesn't specifically state if thats the system, both CPU's or per CPU.

Now I'm guessing one Xeon doesn't consume anything like 500w all by itself but if someone could offer me some clarity on the matter that would be superb.

Ultimately my question is:
What is the peak power consumption of a Xeon e5 2699v4?

500 watts in the test would be for the whole system not for the CPUs.

You can use the TDP as a good idea of the power use of the CPU. Motherboards use that rating for specs about what CPUs they can run. The actual power draw may be more for some CPUs.

Maybe if you explain why you are looking for this specifically it may help clear things up for you. Are you looking for what power supply to get? Simple, add up the TDP of the CPU, the wattage ratings for the other components, add another 30% - 50% to that and you are good.

That was pretty much the answer I was looking for, thanks.

I was actually just looking at super compact ATX cases which can only take 1U server power supplies, nothing I am really seriously considering but just wanted a definitive answer to the power question when it raised it's head.

If you go with a very small case, you have to keep in mind the heat the Xeon will generate. A custom server small case has custom heating design usually with loud fans made to go inside a rack which itself can have fans, and is being cooled by an AC unit in the server room.

I don't suggest a high wattage CPU in a very small case unless you know what you are doing with the cooling.
