I think they got that wrong.....For optimal performance and Overdrive overclocking you need to use one 2x3 pin PCIe power connector and one 2x4 pin PCIe power connector.

It should be one 6 pin PCI express and one 8 pin PCI express

I already posted on this , to recap. Even an overclocked dual C2D+2900XT isn't going to use more than 350W/30A@12V. A good 500W PSU will be fine for most people. Its just to cover the PSU manufacturers who quote peak power levels. Its aimed at the general user who probably doesn't know what a rail or amp means. A more interesting problem is an overclocked 2900XT is getting very close to the overcurrent limit for a single rail. If you have a PSU with very strict OCP limits and the manufacturer has stuck to the ATX spec. Then the cpu is on one rail the remainder is on the other, it could well trip out.Mortster said:http://www.fudzilla.com/index.php?option=com_content&task=view&id=810&Itemid=1
This, claimed, scan of the ATI quickstart guide found with the 2900XT states "A 750W or better power supply..."
This is utter madness, this can't be right can it ?
The problem is....Which PSU's under 600watts come with a 2x3 PCI express and a 2x4 PCI express plug....fornowagain said:I already posted on this , to recap.

But you need a 2x3 pin and 2x8 pin for overclocking...and most smaller PSU's don't come with a 2x8pin.....Gibbo said:Hi there
It does not require a 750W PSU !
It consumes 200W a maximum of 200W at stock speeds.
No you need a 6 pin and an 8 pin. It'll have/need an adapter that converts 2x 6 pin to an 8 pin. So that's 3x 6 pins in total.chaparral said:But you need a 2x8 pin for overclocking...and most smaller PSU's don't come with a 2x8pin.....
So the Card no good if we can't overclock it

Enermax 1000w IIRC.Tom|Nbk said:Gibbo what PSU are you using with your card?, knew this wouldn't be true, Fuad should be banished from the internets, the utter moron.
Gibbo said:I am sure when reviews surface they will let us know about power requirements.
Obviously our system has no issues, but it does have a 1000W enermax in it.
