We strong recommend to use the 8pin interface power port on EXP GDC. You need to use the ATX power. The power need to be enough for the externel graphic card you use. 2. The EXP GDC has DC port (inner diameter 2.5mm, outer diameter 5.5mm), the voltage need to be 12V and the current need to be under 12.5A.So the power is limited by 150W. If you use the externel graphic card you use is over 150W, you can not use this DC port. 3. check and connect the power supply carefully to prevent the equipment damage caused by wrong connection or short circuit. Do not power on it all connection done. : PCB+Plastic+Metal colour: As shown Package Contents: 1 x EXP GDC adapter 1 x Expresscard Interface data lines 1 x ATX PSU power cable Only the above package content, other products are not included.
