Corsair Professional Series Gold AX1200

Hi! :hello:


Wondering if the Corsair Professional Series Gold AX1200 is worth buying, money is no trouble.

I would like to have a good and efficient PSU. :)

  1. It is a good and efficient PSU and at a good price for a 1200watt if you need that much! (There are many more good and efficient PSU's)
  2. Any chance you could tell me some? - My system runs at a 550-600 watts full load.

    And if I'm not mistaken I've heard that PSU's work best at 50% load.
  3. This one would be plenty for you then http://www.newegg.com/Product/Product.aspx?Item=N82E16817139015
    PSU's have the best efficiency at 50-80% load http://www.corsair.com/power-supplies/modular-psus/professional-series-gold-2/ax850.html
    Even the 750 would be enough.
  4. PSU's generally hit their best efficiency point at 50% load. It tails off slowly in each direction. But at your load, I'd get an 850 watter.

    Given today's pricing, unless you have a compatible Antec case, I'd say the XFX Black is a "no brainer".
