What happens if the width and height of a power supply is a little smaller than mine and the length is a little longer. Like 5.7" or 5.51" instead of 5.5"? Will that be a problem? I know width and height matter but if it is a a little longer can it stick out in the case? Thanks.
EDIT: My dimensions of my PSU now are 6"x5.5"x3.5"
