    how loud is it under load the GX
    series aparently have some trouble with a wierd buzzzz sound

    • I dont think its horribly loud and I dont have a buzz noise (yet atleast)

    • That’s because the plain GX is an extremely low end design that can barely put out 500W. It was and is a piece of shit. This newer version, on the other hand, is a pretty decent ATNG design, who used to make server units.

      Also, capacitor/coil squelling is a luck of draw. It can happen to any unit, and gives you the right to RMA if it happens so.

  2. Funny how in the specs it says 6-2 pin x4 times and the review says only 2 and its not capable of crossfire/sli. Why should i buy a 700w power supply when i cant even connect two 7950s? what is it now 2x 6-2 pin or 4x 6-2 pin?

    • swampert543 says

      Actualy, it supports a SLI of 7950, since it has 4x8pin (the 8 pins are made by combining a 2 pin and a 6 pin). trust me, I got one 🙂
