Hello, I have been given a GTX 1080 to replace my RX480, tried to swap it out, both have 6+2 pcie connectors so should be a simple swap, however when connecting the new card i get the "please connect pcie power" notification on boot, the RX480 works fine without issue so its not the cable and the GTX1080 was working when last installed on my friends pc, I have a corsair CX430m (i know this is cutting the limits close) but it should still boot right? i have seen a lot of posts on this error but its almost always a cable issue and havent seen anything that has helped so apologies if its already been solved but i cant find a soloution so far, thanks all
