Alright I'm trying in build my PC and I've come to a crossroads of sorts. Installing an Asus GTX 1070 strixs in a cooler Master elite 130 on am ASRock fatality z170 gaming itx/ac mobo. I've got the GPU in there and it won't go down any further without me applying force the back piece with the outputs is matched up with the screw wholes and is sitting flush. The problem I'm having is the when I look at where the GPU is plugged into the pcie slot on the Mobo I can see gaps where the PCB is cut out for installation like it's not put in all the way. The last time I installed a GPU was back in 2003 it was an FX 5700 and I don't remember gaps like that is this new is it just to accommodate different mobos. The lock on the slot is locked though... Any help would be greatly appreciated.
