Hello All,
Recently I purchased an Evga SuperNova 550 G2 power supply for my little PC. My build is very modest, an Intel i5 4690, Asus Z-97A motherboard and 16 gb of DDR3 RAM. No GPU and no overclocking, just a stock PC that I use for some audio and video editing. Well anyway, my computer is evolving and I am planning on upgrading my  motherboard, CPU and RAM so I thought that since I have my computer opened up I might as well upgrade my PSU as well. But since this is a gradual evolution of my PC I think that I will start with upgrading my PSU first, which brings me to my question.
 
I am looking at installing the Evga 650 SuperNova P2 in place of my current 550 G2. Can I just trade out the power supply itself and leave all of my cables in place? In other words, are the cables between these two PCs interchangeable? That is the deciding factor for me to do this upgrade since my system is already wired up and working fine, I do not want to do a major operation on my PC at this time.
 
Thanks in advance for any responses.

Thank you very much for the prompt reply. I really thought that this was a possibility but I wanted to make sure.
 
I absolutely love my 550 G2 so I wanted to just upgrade and stay with the same Evga Leadex PSU platform.
 
Thanks again.

Here is a picture of my current build, I will update as the system evolves,
 

OK, that was how my PC looked before I upgraded the case. That picture was an old gaming case but just put my innards into a more adult oriented case, a Fractal Design R5.
 
 

 
 
 

Yes, you are absolutely correct but even though I don't plan on OCing or anything, my philosophy is anything that is worth doing is worth over doing.
