Almost certainly. Assuming your not running a bunch of hard drives and a water-cooling system off of it. But first, I would recommend you go over to the power supplies section of the forum and ask them, they'll be able to give you a better idea. That's where this thread belongs, anyway. My advice to you is to buy the best power supply you can afford. As one of the guys on here says, "Cheap power supplies accound for 2% of total system costs, and 28% of total system failures."
