Just ordered a 8800GTS 640MB. I already have a PSU with max output 550w. Would you guys think that its necessary for me to get a new one with maybe 600-700w? If so, any suggestions on what I should get?

Thanks

AMD Athlon Dual Core 4400+
2024MB RAM
GeForce 7800GTX 256 (getting 8800GTS 640MB as explained above)
FSP Group Inc. AC Input 100-240V - 10A, 50-60Hz
Max output power: 550W (Max ambient 30 celsius)
500W (Max ambient 50 celsius)

Not really sure what "amps on +12V rails" is or where I can see it.

Hope you can work something out from this.
