Difference between these PSU???

What's the difference between these PSU? Looks like both of it is the Seasonic X (according the image) and they have slightly different design, why they have different names?

1. 850w
2. 650w

Does it suits my build?

    They are called the same thing, or the same range, it's just pcpartpicker picking and choosing between the marketing name (X-series 650 etc) and the part name (SS-650KM etc).
    Both are good, but are both likely to be massive overkill for your system. It's hard to tell without more information though.
  4. Thjere is also KM3 , KM4. same supplies.
