I just built a new PC with a cx750m (grey label) in it but I was thinking about possibly upgrading to a little bit better corsair psu such as the RMs. My question is, if I stick with corsair psu would I just simply be able to disconnect my current psu and reconnect the new psu with the same wires since they should be the same? I'm not too familiar with building pcs so I'm just wondering if it would just be a simple swap or not.
