  1. A 750w is really unnecessary for only a 7850. A 650 would be plenty. It all depends on how much you are really wanting to spend and how high of an efficiency rating do you want.
  2. Best answer
    A 500w PSU would be fine for the HD 7850. However, if you have an AMD CPU then you should get a 600w PSU instead since they consume more power than Intel CPUs. Which PSU depends on how much you want to spend.

    In general I recommend PSUs manufactured by Seasonic. That includes Seasonic, XFX (all of them), and Corsair (some models). Seasonic's PSU generally do no go on sale or are discounted as much are other brands so they can be relatively expensive, but at least in my opinion no one can match them in overall quality.

    Corsair PSU are a popular choice because their overall quality is pretty good and due to frequent discounts or sales, they are relatively inexpensive. Their CPUs are manufactured by Seasonic and Channelwell Techologies (CWT). While CWT not considered as good a Seasonic, they are still considered one of the better PSU manufacturers around.

    Enermax is another good brand.
  3. I have an intel i7 processor in mine
  4. A 500w PSU would be sufficient. Of course buying a PSU with higher output than 500w means better upgrade options. Like dropping in another Radeon HD 7850 for some Crossfire action. Or a single powerful like the GTX 780.

    Here are some PSUs to consider:

    I'm a sucker for Seasonic PSU so if I wanted a 750w PSU then I would go with the above PSU.
  5. My TX 750 has been good to me. It is the 1st gen one so not as efficient as current models. Rosewill Capstones are also very good PSU's.
  6. Thanks for the help guy's appreciate it ;)
