Thank you guys, it worked. Though I was only able to fit the 6 pin, I don't know if it was just me or if the empty holes are grounded, and I won't be removing the video card to check for a while (as the case is a quite a mess) unless there is a issue with this. I still messed up the HDD LED, upon research it appears I still misunderstood polarity. However now I think I will get it right.
edit: I put the HDD LED correctly, before I had this insane thought that changing the connector side was changing the polarity, but fortunately I snapped out of it
