Hi Mario,

for the sup 720 you need a 2500W Power Supply (which yoou have) and a new FAN Tray. Your original Fan Tray should be the WS-C6509-NEB-FAN, the new is a WS-C6509-NEB-FAN2. A fine FAQ about the Sup 720 you will find here:

You just need to buy high speed fan tray (ws-c6k-9slot-fan2).

Sup 720 has minimum requirement 2500W power supply so you can use your current power supply.
