I am planning to replace the bronze CX500 I have for a Rosewill 750 watt gold unit. Will I have to use the cables that come with the Rosewill unit,or can I just use the cables already inside my case,that came with the CX500? It would be nice not to gut everything and disconnect all my hardware,I amjust concerned about any compatibility issues. I dont want to fry anything,potentially. Maybe I could go with the similar priced CX750,which surely should use the same cables,only its bronze and since I leave my PC on 24/7,a gold is a better choice for better energy savings.
