I tried to pull it out but It takes too much force I'm afraid my motherboard will crack if I put more strength... how can I do it?
the only option is to leave the motherboard plugged in the psu with that cable and move it to my new case but that's just retarded.
On the side of the plug(the side under the wires in the pic) has a locking mechanism. if you can dis-engage that, Usually by just squeezing it, the plug should just pull right out.
You are right in not trying to force it.
thanks, hope I don't break something there
good thing my motherboard is "ultra durable 3" as they call it
last time when I had to put a cooler I had to flip it around since I couldn't remove it... that was a pain in the ass hope this time it works (I remember pressing that pin but maybe I didn't press it hard enough or something since it didn't work).
