Power Supply for New Video Card

[specs1832]

How do I find out what the wattage is to see what video card I can get? The card I'm looking at says it needs 350 minimum. I have a Dell 8200 with mx420, want to get geforce 6600 pci, I have the system info from gabriel topala, it says my pci slots support 5.0 volts and 3.3 volts, and my 4x agp only has 3.3 volts?

The required wattage is nothing to do with the voltages. Its the spec for your power supply (psu) that needs to be checked. If u open your case up and look at the psu, it should have a sticker on it that states its maximum wattage. If its less than 350watts then u will need a new one.

First, I don't think there are any 6600 pci cards, they only come in pci-express, and agp. If you have agp, then you probably could get the agp 6600 and have it work if the card is agp 8x/4x compatible.
