Power Draw from 6 120 mm 3 pin Fans
 

I was wondering what the power draw would be from 6 120mm pans (3 pin)

They are going to be connected to a HWLabs BI Extreme III

My powersupply is an Antect 480W True Power. Would this suffer terribly from having so many fans connected, I also have 2 additional 120mm case fans (Intake/Extraction)

All of the fans are low noise 17db so they should not render me deaf but hey :shrug:

If the powerdraw is too severe what would you recommend?

The fan should have a wattage or amperage figure listed on the label. If it is wattage, just divide the watts by the volts to get your amperage figure.
