MacBook Pro 16" not charging through Aorus Gaming Box 1080 eGPU

Hi everybody,

I have this problem where my Gaming Box 1080 no longer charges my MacBook Pro 16". I bought the eGPU a year ago to use with a 15" and everything worked fine. But, since I upgraded to a new 16", the eGPU no longer charges my computer while in use, and instead actually discharges the battery even faster. Furthermore, it actually tells my MacBook that it's charging, and prevents me from using the apple charger and the eGPU at the same time. So i'm basically forced to use the eGPU only until my battery discharges. Then i have to disconnect it if i want to charge my Mac.

Could this be a PSU problem? And if it is, how and with that PSU should i replace it?

Could it be that the new 16" can't charge fast enough with the power the eGPU provides since it's more powerful?

Any help on this matter would be very welcome.

Thanks and be safe

@martinanthony, Try a different Thunderbolt 3 cable. If you have a USB-C Amp/Volt meter that would help too.

Did you ever figured it out? My friend is facing the same problem, same cable length, same eGPU.

On thorough inspection, I noticed that one of the chips on the PCB was shorted out. This must be the power regulator that sends charge to the computer. I can probably get someone to resolder that particular part, but because it's been burnt, the model number is unreadable.

If someone is kindhearted enough to open up his/hers Gaming Box 1070/1080 and tell me the model number of the chip showed on the photo, I can maybe find it on Aliexpress and save this eGPU from going in the trash. The chip is located underneath the power supply.

@itsage, Dear Illustrious member, do you think it's possible to do so? I have limited experience with eGPUs and this problem in particular.

@martinanthony, I will see if I can get to the mainboard of the Gaming Box this weekend and take a photo for you.

@martinanthony, Sorry I didn't get around to it earlier. I took the Gaming Box PSU out to take this picture. From what I could see it's 6508 GV7683. The IC next to it is identical in number so you could double-check on your Gaming Box Thunderbolt 3 mainboard.
