Power Consumption

The 9900KS really loves power, it eats it up quite well, and while the difference here isn't the same as what is on paper (95W vs. 127W), it is more realistic because we know TDP numbers don't mean much.

Overclocking

Intel Core i9-9900KS (Coffee Lake) Processor Review 25 | TweakTown.com

The CPU runs hot, but we were able to pass our HandBrake test with a 5.2GHz overclock. At 5.3GHz we were able to run CINEBENCH. We set 1.375v with Turbo level LLC, activated XMP, increase core current limits, and unlocked the power settings in the UEFI.

If there was ever a reason to increase TjMax, the 9900KS might be it, although we were impressed with our temperatures here. We used a closed loop all-in-one water cooler, and if we really wanted to run this at 5.3GHz or even 5.4GHz we would use a custom loop.
