1200w is a bit overkill for most PC's, but the peace of mind knowing that I never have to worry about my PC having enough power, lifted a wait for my shoulders that I didn't know was there. It gives me the freedom to upgrade the rest of my PC in the future without worry. If you can afford it, I definitely recommend it.
