I'm currently using the gtx 1070 version of the g20 and I bought the gtx 1080fe to upgrade it.
Question, do I need to change jumper settings to combine the power of the bricks ? It has 180w and 230w power bricks.

You shouldnt need to... the G20 has been ran on a 1080ti using the 230w brick by another user but typically... because of the draw rates of the 1080 being slightly higher it wouldnt hurt to invest in a slightly higher wattage brick. voltage of 19.5 should be fine however.
