850W PSU not enough for an 8800GTX?

[VortX]

I've run one off a 550W PSU. Try not using the PCI-E dedicated leads, but use molex to PCI-E converters from a couple of other power leads.

Also, have you tried the card in another machine?

Why do you say this? I have mine running off 2 dedicated PCI-E cables? Would this have something to do with my OC restrictions...

While we are on the subject I will ask about that aswell:
When I OC my BFG 8800GTX OC I can get to about 640/2100 but if I go any higher the system will just crash, it doesn't have any artifacts it just crashes? I had the impression that it should go like this when OC:

Stock: Stable
Slight OC: Possible artifacts
Then further OC: crashing and wierd errors.

But mine goes like this:

Stock: Stable:
Slight OC: fine
Further OC: Crash

Please help as I would like to OC my GTX further?

Might be easier to start your own thread

One reason to use molex connectors from different rails is to ensure that more than one rail is providing the power, hard to be sure about that with the pre-wired connections as often they would each be using only one rail.

On the other hand few PSUs have enough rails to power two PCI-E connectors from 2 different rails each anyway.
