Would you say that in terms of power delivery, the Aorus ITX will be the top choice? Given that I'm looking to drop in a 3900x then I wouldn't want to see the most power hungry of then line up (so far) held back.
have to see the Impact , features same VRM , 70A beasts as Aorus. Believe it is 8+2 vs the Aorus - its the controller thats the blank area ..
Aorus are the only ones to use 16 phase PWM controller , MSI and Gigabyte use IR35201 . ASUS used ASP1400CBT VRM in the Hero/Formula didn't go down well.
MSI new 14+2 Godlike uses IR3599 VRM controller.

Phase multiplier -
@tamzzy - asus could use this and correct their Z390 mishap
Asus ITX boards are either using Doublers on the Mosfets or Phase Multiplier controller- roughly meaning 2/4 power phases plug directly into one PWM chanel to achieve 8+ phases for Vcore .
Aorus would be better then the Strix, handles more power and in a better way. as for Impact, on theory Aorus could be better on how it delivers the power, even though Impact takes more amps across the VCore . Then it boils down to cooling and such .
Gigabyte have the better Customer service and RMA being UK based, but asus with Bios
seems like you'll be pumping 1.4v + on 12 cores
