Hey Logan I have a question. I have a 430 watt PSU and I am wondering if that would be enough to power a gtx 660, thanks-Cody

As mentioned, it requires more information about your system.
But, with that said: BEHOLD! The answer to your questions lie within http://www.extreme.outervision.com/psucalculatorlite.jsp
