Thanks
I have just been looking at my Z390 Aorus Master in comparison the my two Z690 Aorus Elite AX DDR4's
The vrm efficiency seems crazy bad on the Z690's even at idle
if its correct so be it but its so high it looks to be a calculation error maybe?
16+1+2 Direct Digital VRM Design
70A Power Stage
Premium Choke and Capacitor
50% VRM Losses at idle?
26% VRM Losses at load?
Z390 Aorus Master at idle is 16.xx w Power (Input) 16.xx w Power (POUT) i9 9900K 52x (1-3c), 50x (4-8c)
Z690 Aorus Elite AX DDR4 1 at idle is 30w Power (Input) 20w Power (POUT) i9 12900K 53x (1-3c), 52x (4-7c), 51x (8c)
Z690 Aorus Elite AX DDR4 2 at idle is 38w Power (Input) 24w Power (POUT) i9 13900K 58x (1-3c), 57x (4-5c), 56x (6-7c), 55x (8c)
Z690 Aorus Master at idle is 23w Power (Input) 17w Power (POUT) i9 12900K 53x (1-3c), 52x (4-5c), 51x (6c), 50x (7c), 49x (8c)

Load Line = Normal
9900K Z390 Aorus Master
IA Domain Loadline (AC/DC): 1.300 / 1.300 mOhm (Auto)
Voltage/Frequency Curve: +20mv (adding the 52x multiplier for cores 1-3 results in around a 22mv undervolt at 50x so i had to bump the table 20mv for the Curve)
Otherwise it used the 50x vid for 52x and 50x got less etc..
