It's slightly more forward (away from you) than center.
This places the "plane" of the supply on the incline of the board, to where the lower pair of rubber feet on the CIOKS SOL, are on the horizontal plane that the other six rubber feet of the board are. It sits perfectly level with the SOL having those two points of contact along with the boards six rubber feet.

I have a short power cable, supplied with the OPUS OEM power supply, that I am using to connect to my snake power cable with the XLR and 1/4" TRS cables in it and then in to the SOL.
