Seasonic X650 Gold vs. X660 Gold

Been looking at the two models for a while now. Still can't figure out which model is the upgraded version. There gotta be some differences between the two models.

  1. One just outputs 10 watts more.

    Really, they're going to perform identically.
  2. X660 is the upgraded model. Also the same PSU used for the Corsair AX650

    Buy whichever one is cheaper IMO, both are good.

    LOL.... duh... I can figure the math out. JK... Anyway, from what I saw online, the 660w has a newer technology than 650w, or something like that. But really they didn't go too deep to have a further discussion.

    Yes, the upgraded version. That was what I was going to say.

    The x660 is slightly upgraded; little different organization but performance and efficiency is so close to each other that it doesn't matter. The Corsair AX series is basically the original X and the slightly updated X series combined.

    Basically, whichever is cheaper is the better deal since they're nearly identicle in everything. Efficiency , quality, and power output. Only difference is the price.. XD
