I was running an ASROCK A580 Challenger and I got the same B Series model and I tested the A580 against the B580 and thought I would share my results.
I will say either Intel made massive improvements in power consumption or else their software that reports the Wattage being used is way out of whack.
My A580 Idled at 41 Watts and used 57 to 61 Watts running Handbrake,it ran at Idle 41C and when running Handbrake at 48 to 51.5C
My B580 runs Idles at 7 to 9 Watts and bounces to 10 or 11 Watts for 1 to 2 seconds and mainly always runs between 7 to 9,running Handbrake it runs between 27 and 31 Watts,it Idles at 36C and runs at 41 to 42C running Handbrake.
The video file used was downloaded from the link in the thread and the file is called big_buck_bunny_480p_surround-fix.avi and is 210mb and 854x480p

I ran the same video file threw 5 times at 854x480 the same resolution as the source file and used Intel H.264 QSV encoder in Handbrake and left the compression at 22.
I have an ASUS X870E ProArt 9900X cpu and 32GB DDR 5 Ram
