Okay thanks for the help, am also wondering what power cables do i need for MSI RX 580, on those gpus i think it goes 2x 8 pin power inputs, so do i need 2x 8 pin cables for those gpus that will use 2x 8 pin slots on the psu or i can use one cable that forks on one end into 2x 8 pins and on the other side has just 1x 8 pin for the psu ??
