Subject says it all:  I have the Aurora R13 with a 750w power supply. You can 100% tell that the system doesn't always have the "oompf" it needs and I see Aurora R14's have a 1000w power supply now, but I also can't see anything about it. Anyone have experience with that? I seriously thought about going to Amazon - replacing the MB and case; getting a 1000w power supply that way. But I'm willing to bet everything is proprietary on the components. Thanks!
Aurora R13, upgrading power supply?
