I have just brought a nvidia 8800GT. Iv installed it and run the driver update. But windows say that the card is not getting enough power and slows it too a crawl. I think that its my antec quatto 850W because iv heard that theres problems with them running this card?

Is this right? and is there a way to fix it?

In order to get any help, you need to post your system specifications that have to do with the problem. In this case, your PSU wattage. I have no idea how to check your PSU type from windows itself and i don't think its even possible, but there should be some label on it if you open the case.

iv tried several ways of worig it up and none of the work. I have read on other forums that antec power supplies have this problem. Just wondering if anyone else have had simular problems?

Wow ... 850W is a monster. Mine is Antec 550W and I too have a 8800GT. I use the dedicated PCI powerline with no splitter and I don't seem to have any issue with power.

Im using a Thermaltake 500W PurePower PSU. Are you using Vista? Open up the latest Version of GPU-Z and see if you are running at 16x for PCI-E. There is a power option under vista that will decrease the bandwith to save power, I turned it on and it made my 88GT act funny so I turned it back off. Just set your power scheme to the high performance setting and try that.

I was actually talking about the wattage from the PCIE connector on your power supply. I think you can check this in speed fan but i am not sure, maybe your PCIE connector isn't feeding the 8800gt enough power? Antec is a good brand, but your power supply may be broken. My fault for not being clear, sorry :) .
