Recommended Power for SLI?

[imported_Noob]

How many watts does your PSU have to be to run SLI stabily? For both 6800 Ultra's and 6800 GT's?

I'd suggest at least a 450W, though people have done it with less.

To be absolutely sure, nvidia has a list of approved powersupplies. I'd recommend a brandname PSU of 500watts or more to be safe.

Would it really vary if you had to 6800U's or GT's, considering the 6800U requires more power. And how would an Antec TruePower/TruePower 2.0 550 Watters perform? Or do they have to be SLI ready specifically?

Nvidia only has 5 PSUs on that list, as for the OP's question a high quality 450W (might be a bit low) or 500W will do fine just make sure it has 2 video card connectors.

An ultra only uses a few more watts than a gt.

An Antec Truepower 550 should be just fine for an SLI system.

As long as it has plenty of reliable power, don't worry too much about nvidia's seal of approval.
