Hello there, I am looking for a relatively decent upgrade from my current PSU, I currently have an ARK 500W power supply, it looks really shady, and I am wanting to step up to something more solid. I am looking for a PSU with enough wattage to run a 7870, or possibly a 7950. While still having some breathing room. Anyways, my price range is probably around 60-70 dollars. If anyone has some suggestions, I would really appreciate it. Please and thank you.
