Ta grafa ima 6pinsko napajanje sa zadnje strane
The R7790 has a typical power draw of 85watts under full load, allowing XFX to utilize a single 6-pin connection located at the rear of the R7790. AMD's ZeroCore Power technology keeps the power draw at a minimum when the GPU is in the idle state, reducing power consumption down to as little as 3watts of power.
