Help me understand External GPU/Intel Thunderbolt 3

[shahidrahman]

I just heard someone talk about this and I did a lot of research and asked around about this but I still am lost about its capabilities. I hard you can use a desktop graphics card with your laptop using the external GPU product. I also head the Intel Thunderbolt 3 is being released soon and it can do the same. The thing is when I went to Best Buy, I asked a guy about this and he said that's almost impossible because of the watts needed. He showed me how the gtx 770 and gtx 980 need about 200-300 watts but the intel thunderbolt said it can only do 100. Is this really true? And will this product work with the Asus ROG series?

My Laptop: Asus Rog G751 JT

Yes when you find this information please post it. We here are just users helping other users. As of today Asus has released no specifications for the model G700. As far as the 100 Watts supplied by Thunderbolt 3. Its easy if you have an external Video card you would also have an external power supply for that external card Yes? So far we have no information than what is publicly published. So as I started this reply if you find some hard new information please post it here for us.

I forgot where I found it by some Chinese retailer manufacture & sell M.2 PCI-E ( for output ) extension cable that has PCI-E x16 slot ( for input ), though I not sure the cable length will manage to baypass the length of our laptop with enough comfortably distance
i.e the external slot might sits very near the laptop end, thus heating all your working surroundings.

This is completely irrelevant as it has an external power supply and the thunderbolt is used for information transfer purposes only. Of course you can't power a 200w card through the Thunderbolt port.And about the question of whether or not it will work with the G751 it will but because it's not a thunderbolt 3 as far as I know it will probably limit the transfer speed and might cause some stutters or bugs on high end GPU's ( imagine if you plug a 980 in a 4X pci-e instead of a 16x one it's kinda the same deal).
