Does Alienware 18 R1 have enough power for a GTX1070 MXM

[Sebastian Ramirez]

Hi, Im going to get an GTX1070 MXM soon, but just wanted to be sure, does the Alienware 18 R1 motherboard have enough power to handle the GTX1070's full power? (It wont burn out or something like that?)

 

Thx

Yes, many have done the same upgrade in the past with good success. @ssj92 may have a few things to say on using a better card than the 1070, maybe an RTX 3050 or 4050 would be a better buy.

Hello, they are impacted by the TDP bug, 40W or fluctuating between max TDP to 40/55W.

 

So it's not worth it since they are limited by the Optimus MUX Switch.

 

I got the M6800 to work with the modern RTX Ada and there was no TDP bugs.

I believe this issue was found by @janepa and I have to still disassemble my aw18/m18x laptops to find the resistor to mod to fix the issue.
