Connecting a 480GTX

[Guest2]

I have an Antec truepower 750watt PSU and a new 480gtx should be arriving today.

To connect it an 8 pin and a 6 connector are needed.

I'm guessing that the 12v4 or 12v3 PCI-E connections (that are red) on the PSU are required to connect the 6 pin connector? Which of these do I use or doesnt it matter

Can the 8 pin (6+2) then be used directly from the PSU?

Would the PSU be able to handle 2 x 480s in the future. I think they take around 250watt at lead each

It would seem the PSU has 2 x 6+2 pin PCI-E power cables hard wired and 2 x 6 pin PCI-E modular cables.

Use one of the 8 pin cables hard wired to the PSU and one of the modular 6 pin cables to share the load over the PSU rails.

You really need a good 850W+ PSU for SLI'd GTX 480's.

Thanks.

I currently have a [email protected] and 2gb memory. I imagine I will upgrade my whole system before I get a second card. Just annoying I bought a 750watt psu not long ago from here and I doesnt support SLI (even though it says it does on the box and when I bought it)

Maybe by that time, there will be a new card that uses less power

The PSU does support SLI and Crossfire it just depends on what cards you're using.

It would be OK for 2 x GTX 570's or 2 x HD 6950's for example.

It could possibly run 2 x GTX 480's but you'd be really pushing it and that's not good for the PSU.

False advertising surely? Shouldnt it say

SLI ready...
(excluding 480, 6970 and a load of other cards)

Good luck taking that one to Court.

Think about the 500W PSU's which are SLI Certified. You may be able to run SLI'd cards but only low end.
