I currently have an MSI GTX780 Gaming, that is powered (barely) by an old Enermax Liberty 400, I was hoping to one day upgrade to an SLI system, but until I can replace old faithful, I know that I can't. My liberty isn't fully modular, the cable braid is loose and none too flattering, but it is my power supply and it has served me well. Of course, a nice shiney new power supply, would make it so much easier to upgrade my computer, and see me through the next few years.
