Just bought ATI 4850x2 need help please.

[Leopold Butters]

So I ordered this card from newegg 2 days ago, and I was going to buy a new power supply to run it. But I am finding different sites with different system requirements. Some sites say it needs a 650watt supply while others say 450. Now i have a 450 and would rather not buy a new one, so to anyone who ones this card can you confrim the system requirements please.
