Hi all,

I realized I could charge my 2017 Macbook Pro by connecting the USB-C cable from my Macbook to the Thunderbolt 3 USB-C of my ASRock Z370 motherboard.

Looking up the thunderbolt 3 tech, it mentions the following on power delivery:

Power (based on USB power delivery):
-Up to 100W system charging
-15W to bus-powered devices

The power brick of my Macbook pro charger says it's 65W.

Does that mean when charging my Macbook, it could be drawing up to 65W from my power supply from my PC? Seems like a lot. Thanks!
