Best PCIE Powered GPU

[jonnyrb]

I'm looking for the best GPU that requires only a PCI-E connection OR my psu says it has a 16amp and 18amp 12v rail, However I only have 1x6-pin connector.

I was hoping for something like a 5850, but I'm not so sure anymore

p.s. I'm an amd/ati fanboy

edit: Currently have an 8600 GT // On board 4290 HD.. =\

Click on the link in my sig, you'll find a good summary of video cards in different price and power needs ranges. A 5850 needs 150w of power, and the cards I see have 2 6 pin connectors.

A 550ti only uses 1x6pin connector. I ran it on my 400 wat psu and it worked great. Now I have them in sli on a 620wat psu.

I have an Radeon HD 5770 which runs on only a single connector. I have a 620W PSU and it works just fine.
