I tried using guides, but they just leave me in doubt and I want opinions and advice from an expert community.

Will the PSU be able to run this system with a Radeon HD 7870? What about a Hd 7970? I don't plan on using crossfire because I'm on a single monitor at 1080p. The extra card would just be a waste to me. Newegg PSU calculator says I need around 500w.
