what we did is we used the cathodes that were used off the light off "Rack & Roll" we also have a fan on our board that blows under the laptop... what we did was put a "female connector" hard mounted on our board and ran the DS fan and lights off of the power cord cumming from the transformer that is part of the kit it ran for an hour and a half one time and was fine the cord, which should be the same as the one at competition, worked great..... no need for another power supply
