You'd be better off just getting a new power supply. Cyberpower never ever uses credible power supplies for their computers. Chances are it actually doesnt have enough to power the card.
I hope you didn't pay more than $500 for something with a GT610 in it.
I wanted to build one of my own but being in high school I had to convince my mother to pay for it. Lol. There is no way she would have put any money into it if I were doing it myself.
I actually got the pc on sale. It was on amazon for like $100 off. I knew it was a bad deal compared to what I could build. I paid $515 for it.
