  1. Yes, that PSU is more than enough for your current setup! The 7790 is a relatively low powered card.

    According to AMD, minimum requirement for power supply is 500w or greater. But if your PSU is 450w with 80 plus, then its ok.
  3. Is my power supply 80 plus?

    Its not 80 plus.
  5. So will it work?
  6. The recommended PSU is more of a "safe" range. My 7950 recommended a 500W at least... There is no way the 7790 and 7950 are similar in power draw.

    If you wanted to be on the safe side, up your PSU to a 550W

    Try first, then you will learn from your experience.
    Update: Better get higher PSU.Just in case you want to upgrade in the future, you dont have to be worry about your PSU.
