What shall i look out for in a PSU? Fan size? Efficiency? Wattage? Ampers?
Is there a difference in Non-Modular, Semi-Modular and Fully modular?
--Is performance better in a non modular and semi modular?
--Is there a drop in performance between semi and fully modular?

More about which
  1. Modular vs non-modular design has no bearing on efficiency or performance.
    I would go with either the Antec or Corsair PSU.

    Why?
  3. Simply because I have used both brands before and know them to be good.
  4. Like stated before, Corsair or Antec, both are much more true to their 80 plus ratings than Cooler Master, OCZ is pretty good but I never have personally owned one, although my friend uses an OCZ. Cooler Master is a no go for me as I have heard they skimp on quality.
  5. The Antec is a very solid unit manufactured by Delta Electronics.

    The Corsair is also a very solid unit made by CWT ( Channel Well Technology ).

    The OCZ ZX is manufactured by Great Wall and also a very good choice.

    You would do well with any of the 3. With the Corsair and the OCZ being the same price you could really flip a coin to decide.

    The Corsair supplies 62 amps on the 12v rail.

    The OCZ supplies 70 amps on the 12v rail.

    So you end up with a more powerful PSU for the money with the OCZ.


    As stated above I would not even consider a CoolerMaster.
