I don't have another power supply to test with other than the one in my computer, but I really don't feel like disconnecting everything from both computers and switching lol. I'm lazy so we're waiting for cyberpower to respond to our e-mail. The reason I didn't build a computer for my sister was because if I was to mess something up or couldn't get it to work, then it's on me and there's no tech support or free help I could get to fix my mistakes or errors. I didn't want anything to be blamed on me as I had only built one other computer before. I have since replaced everything in my computer and feel much more comfortable building and troubleshooting common problems. But as far as this goes, cyberpower apparently isn't too great and I feel bad for her.
