More about psu 7770 gtx 650ti
    it a seasonic unit that been rebranded. with the 650 or 7770 you want to have 550 or larger power supply so there rom on the 12v rail for the gpu and cpu when it under full load. buying small 300w power supply wont work you just blow up your rig.
  2. The 650 Ti needs a 400 Watt or greater power supply and the HD 7770 needs at least 450 Watts. So, plug all your components in here:
    and based on the recommended wattage, pick a power supply from a reputable vendor (such as Seasonic).
  3. but some people said that 400W is enough to run hd7770
