If you have 1950X on an asus mobo, please let me know the CPU, not the entire PC, power consumption reading using asus AI suite . I am interest at the figures when running 3.3 and 4.0gz clock speed under windows 10 professional power option of BALANCED plan.
I think that chip is up there with the most power hungry chips on the market. Almost all other CPU's you might consider will use less power, excluding something like the 7980XE which costs your first born child anyway.
The 7960X will beat the 1950X in performance and power consumption if you are really worried and willing to pay a little extra.
Also keep in mind that ASUS and a few other manufactures have a default OC setting enabled in bios. Out of the box and ASUS motherboard clocks the 1950X to 3.7Ghz. You have to disable the OC setting (sorry I can not recall what it is called in bios) and the chip will then run at its stock 3.4Ghz. So some reviewers do not know this and are putting out what they thick are stock power consumption and temp. These are not correct.
Its not a terribly hungry chip on idle like most people think. My previous setup, which was an X99 intel 5960X, ran 180 watts at the wall on idle (4.7 OC). Turning on power saving options brought that down to 130 watts at the wall. My current setup (Same everything, except board and CPU) idles at 120-130 watts (Cool n Quiet is not selectable on this board, and hwinfo doesn't detect any downclocking, from 4.2 OC 1.45v).
If you're moving up from a 'regular' setup to an HEDT one, of course there will be a power difference, but AMD right now is in a very good spot, power-wise. Meanwhile intel HEDT cpu's are using 500 watts just on the CPU alone lol.
CPU Package Power bottoms out to just under 50 watts for me @ 4.2GHz 1.45v.
BTW, the setting you are thinking of is "Core Performance Boost". Turning it off, though, disables the chip's turbo and XFR frequencies completely. You really should be letting it stay on, as the chip will still respect the 180W TDP and not exceed 180 watts CPU Package power; It will increase and decrease frequency and voltage dynamically to stay under 180 watts, but turbo up as high as it can (up to 4.2GHz XFR) under stock settings as long as temperatures allow. The board is not responsible for the behavior of XFR; The CPU itself does XFR all on its own.
Of course, if you push the chip frequency past it's own boost frequency, it goes into bypass mode, ignoring 180W power limit, and no longer uses XFR, so you could see a performance loss when running single-threaded loads, depending on how far you manually OC.
Thanks ssateneth.
Are you saying that if I want to respect the 180W TDP ( I will air cool it), do NOT bother with OCing it as the CPU will try to run as fast as possible, right?
If it is true, then I do NOT even need a mobo that can be OCed.

Pretty much. Threadripper is very good at respecting it's TDP. It'll automatically boost cores a lot on single thread loads, or balance out speeds on multithreaded loads when approaching TDP. If you don't plan to push the CPU past it's normal boosting behavior and to air-cool, then a plain-jane board will do you just fine. All TR boards exceed $300 new though. The Asrock x399 Taichi is on the lower spectrum of price and performs great. There is also an asrock Fatal1ty X399 Professional Gaming on ebay (bidding only) and you can bet you'll get a much better price than new. Only difference between that and taichi is a 10GbE ethernet and different sound chip IIRC.
None that I have noted. Within AMD CBS section there is a C-TDP setting (IIRC), even adjusting that has no effect.
