I'm no expert, but u need to plug in both of the 6pins. If ur psu only has 1 6pin, then u must use the molex to 6pin cable that came with the card. And how many watts and how many amps does ur psu have on the 12v rail? If it only has 1 6pin, then it probably isn't ment to deliver more, but yea tell me ur psu, otherwise cant help
