I just built my pc it starts up with the cx 430 watt on my motherboard the atx connector to power up the motherboard is loose like if I move the cable it shuts off immediately however i can move the case up and down side to side with out any problem it wont unplug. So what I am trying to say is that it doesn't lock on as tight as it's suppose to. I am just wondering if this is normal or not because my pc has been running fine i haven't encountered one flaw about the computer beside this loose atx cable.

My PC Build:
MOBO: MSI A78M-E35
GFX: r7 260x
CPU: Athlon x4 760k
PSU: Cosair CX430
RAM: Kingston HyperX Fury 8GB
HDD: Western Digital 500gb
 

Hey man thanks I just wanted to make sure, as long as I know it's not my motherboards problem I'm fine.
