Will a 430W PSU be enough for a gtx470?

Hey all,
I've got a fairly old setup and have just acquired a GTX470 GPU. The Nvidia website says it requires 550W and my current PSU is only 430W. I was wondering if 550W is a definite requirement or just more of a recommendation, and whether it would be safe or not to upgrade GPU with the smaller power supply until I can upgrade to a larger one in a few months?

Any info would be greatly appreciated :jap:

System is currently:
Board: Gigabyte GA-EP43-DS3L
CPU: Intel Core 2 Duo E8500
Graphics: Nvidia 9600GT
RAM: Corsair Dominator 2GB DDR2 x4
PSU: Thermaltake XP550 NP (430W)

    A GeForce GTX 470 needs 38 amps on the 12v rail and a 550 watt power supply.

    430W Corsair can't run it.
