Hi everyone I was wondering if I could have some advice on my new evga 8800 GT. I installed the card and am having artifacts, and its saying I don't have enough power for the card, but I have the power adapter plugged in. I ran speed fan to figure out what voltage was coming in and it says 9.82 v. I have tried the dual 4 pin to 6 pin adapter that came with the card and it still shows up 9.82v. The power supply I have is the 1000w antec quattro. I called evga and they said it was either the card or my power supply. Going to try a volt meter when I get home. Any ideas would be appreciated, Thanx
 
Your power supply is faulty. Antec is aware of problems that exist between the 8800 series nvidia cards and the Antec TPQ 850 and 1000w power supplies. Take it back to where you bought it and get a different one.
 
You might, check the 12v rail and see what its giving you.
 
That seems like a really weird problem... I hopefully haven't damaged the graphics card or anything. It was doing some really crazy things when I tried to run Crysis and Quake Wars to just test the thing. I am prolly going to jerry rig my old power supply and use the dual molex to pci exress 6 pin adapter to power the graphics card and see if it fixes me issue... and then contact Antec

It won't be damaged but all it does it is run the card at half speed or so. Personally I wouldn't bother contacting Antec unless you can't return it to where you bought it and besides you don't need a 1000w power supply :) Buy a good 750 or 800
 
I am fairly sure I can't return it because I have had it for a while less than a year. If I did go for another power supply what are some good options? I only got the 1000w just to make sure I wasn't going to have any power issues (and it had positive reviews)

Go for something like the Pc Power & Cooling 750w its what I run and have no issues.

Its worth checking as its a design/manufacturing defect.
In the UK, you can get a company to repair or replace a product outside of the warranty period if it fails outside the expected operational life of the product.
Hopefully there is a similar policy where you are.
 
I still am going to try to see if I can get the issue resolved with the Antec power supply. The other one is more of a last resort measure :) I need to research the multi rail vs single rail too.. right now if i can get something to just work I will be happy
 
Well I came home and hooked up my old Ultra 550w power supply it doesn't have all the "correct" connections, but the graphics card is running now .. was testing out the crysis demo at 1280x1024 with everything running very high on vista and it ran perfect. I saw that the revision number on the Antec Power Supply is rev 3, which i saw on another forum was the one that was suppose to be fixed with the 8800 cards. Calling Antec to see whats up with his now.
