Finally, the 430 requires an FDD power connection for the front panel. The 430 V2 and Black 430 use a 3-pin power cable from the display to the 3-pin connector on the 24-pin ATX main power connector of the power supply. Therefore if you are swapping out the PSU you will need to contact Antec to purchase a special 24-pin Extender with the 3-pin connector to power the display.
