Modify an Akitio Node to supply more power to MacBook?
Hey guys! I'm new here and this is my first post. I've recently purchased a second-hand Akitio Node and a 980 Ti to use with my 2016 13" MacBook Pro (w/ Touchbar), and although I stayed within my budget, I realized that I'll have an issue powering the laptop itself with only 15W. Is there any way to modify an Akitio Node to supply more power to the laptop, and less to the card? Or is there any power supply that can be swapped out with the Node's to give the laptop more juice?
Suppose that this isn't possible. In that case, does anyone here know if the MacBook Pro is capable to sipping power from more than 1 TB3 port at once? I'm trying to avoid purchasing a new charger (I need the one that came in the box for other purposes), and I have some lower wattage chargers laying around. Will the MacBook take power from the Node AND my charger, or will it default to only using the charger because it's a higher wattage? This is important because neither the node nor the charger can power the MacBook on their own; they need to work together.
And finally, if neither of this can be done, does anyone know the cheapest reliable 3rd party MacBook charger?
You already have a Macbook USB-C charger so can answer the second part of your question. Connect the charger it to your TB3 port, Node to another TB3 port and see what macOS reports as being the AC charging wattage.
As an aside, if in the US can grab a US$250 Sonnet Breakaway 350 with 60W PD.
I don't have a node yet, but I'll be receiving mine in the mail in about a day. I'll try using it and the USB-C charger at the same time, but I don't see how this would give me any meaningful information. I know the laptop won't take more power than it needs, so it'll just be taking the 61 watts the USB-C charger provides. This doesn't really answer my question of whether or not it can take power form multiple sources.
About the Intel TB3 firmware, I'm assuming that's not something I should try tampering with, right?
@Ray, the MBP can only take power delivery from one source with the highest amount. Like @Nando4 said, the PD of 15W is baked into the AKiTiO Node firmware. Swapping for a more power PSU won't help change that.
