8800 GT power issue

[swoop56]

I have a new build that includes a Gigabyte GA-P35-DS3P motherboard.

When I boot and windows starts up, there's an error window from nvidia telling me that my video card doesn't have enough power and will run in low power mode.

What I don't understand is that I have just one 8800GT attached to a thermaltake toughpower 850W power supply.

This powersupply was just powering up two 7800GTX's in SLI the other day. So what could it be?

Both the 6 pin connector is in and the motherboard 4 pin molex connector is attached. Drivers are 169.02

I remember someone having some problem with some motherboard and their 8800gt giving them an odd error. It may or may not have been the DS3 and a low-power error. Anyway, I think they fixed it by rolling back the BIOS or updating it, idk.

Sorry for the vagueness, best of luck to you.

I had the same problem.
I bought an XFX 8800GT the 1st day ZipZoomFly had it.
Plugged it into a Intel brand G965 Q6600 system with an Antec True Power 850 PSU.
Got the same error as you did from the Nvidia drivers saying I did not have enough power.
Swapped PSU (Seasonic s12 500w) and went along my merry ways.

Something is wrong with these 850 PSUs.

if the PSU is modular, you'll find the first 2-3 slots has a seperate 12v than the next few slots.

Try saving the first few slots only for the vid and the rest for the non-vid related power devices.
