You would also need the 2x6-pin to 1x8-pin adapter so you have 3x8-pin connectors. May sound a bit hairy but it seems to be working well with a 750 watt PSU for the peeps in this thread 
  [IMAGE] [IMAGE]   Hello, I have ran into a problem here. I am kind of new to the whole PC gaming world and when it comes to the technical aspect of it I am just a complete noob, but a quick learner. I currently have an Alienware Aurora R13 paired with an i7-12700 and an RTX 3090. I recently purchased from a friend of mine an Dell OEM RTX 4080 which measures 12x5x2 inches and it fits perfectly on my R13. Now, here is where it starts to get complicated for me, I noticed that this Dell 4080 has a different power connector which now features a 16-pin, but the cables that come out my Dell 750W Platinum PSU as you can see on my images only has 4 cables consisting of 2x8-Pin and 2x6-Pin. I was told I will be needing an adapter but I was not given a link or image to one. Any help will be much appreciated. Thanks.
