I've been considering something like this which, is 700w 80+ bronze which, is also seems to be a reasonable price.

I'm not sure what atx size PSU means but, do you think this would fit my case as far as lining up for the screws goes and have the proper connections? It shows it has a 6+2 and an 8 pin. Would that work for a GTX 970? It also comes with 6 sata's and 3 pata's which seems like it would be enough and, is semi modular so in theory, if I needed more cables for other components I could just buy some more cables.
