No Power = No R600?

[GTaudiophile]

Just reading Anand's second CES article:

http://www.anandtech.com/tradeshows/showdoc.aspx?i=2905&p=2

Seems that R600 will need a new 8-pin PCI Express 2.0 power cable.

I wonder if this is one reason why R600 is taking so long.

Too bad peeps might have to buy a new PSU for it

The card had better kick arse if so!

 

[JackBurton]

We'll see. I'm still waiting to build my machine, so if it needs a new power supply, it makes no difference to me. I need to buy a new PS anyway.

 

[Creig]

I'm guessing they'll just include a molex to 8-pin adapter with the card for those who don't have a power supply with the connector.

 

[theprodigalrebel]

I'm sure there will be Molex/6-pin PCIe to 8-pin PCIe adapters. Just like when SATA hard-drives came out and PSUs didn't carry SATA power connectors.

 

[CP5670]

I wonder why they're making the switch for only two additional pins. Would they really allow a lot more current to pass through safely?

 

[Captante]

That would be seriously stupid ... why not just go with 2 x 6 like the 8800GTX?

I believe the 8-pin power connector is a requirement in order to be compliant with PCI-E 2.0 specifications.

I was unaware of this ... link to source?

Q11: I?ve heard mention that PCI-SIG is working on a new graphics spec ? what is it? How is it different from the existing PCIe x16 Graphics 150watt-ATX 1.0 spec?

A11: PCI-SIG is developing a new specification to deliver increased power to the graphics card in the system. This new specification is an effort to extend the existing 150watt power supply for high-end graphics devices to 225/300watts. The PCI-SIG is developing some boundary conditions (e.g. chassis thermal, acoustics, air flow, mechanical, etc.) as requirements to address the delivery of additional power to high-end graphics cards through a modified connector. A new 2x4 pin connector supplies additional power in the 225/300w specification. These changes will deliver the additional power needed by high-end GPUs. The PCI-SIG expects the new specification to be complete in 2007.

If you are going to run crossfire, OCZ announced a 2Kw PSU. It just might be enough

Where did you read that? Here is what I read;

These power supplies feature the new 8-pin PCI Express 2.0 cable design and will allow the use of two R600 cards.

Two as in Crossfire, not one. Unless I missed something.

Hardly. The 8800GTX was rumored to pull 200+ watts before it was released, too. Why don't we wait for the hardware to show up before buying stock in nuclear power plants, eh?

Maybe the article meant there will be two 8-pin connectors?

 

[Corporate Thug]

wouldnt there be some sort of converter? when PCI-e first came out, most cards came with a molex to pci-e scenario

 

[Peter]

The eight-pin plug is introduced because six pins can't feed the power. Now, how exactly would this work with an adapter from exactly that insufficient six-pin plug? Think again.

 

[CP5670]

It would probably have multiple 6-pin adapters on the other side (or a 6-pin and a 4-pin molex), like the existing PCIE/molex converters do.

 

[trOver]

my guess is that the adapter, if there is one, will have either 2 or 4 molex connectors going to a single 8 pin pci-e connector

 

[mamisano]

What they should do is go 10 pin, for future expansion. Seems like they change the requirements every year or so...

Hahaha...I remember about a year and a half ago when I posted up PCP&C's 1Kw PSU for $450. 2Kw!? Holy cow!

 

[schneiderguy]

Enermax will have an 8-pin cable available for their current Liberty series that will allow the use of a single R600

We asked about potential cable adapters for current power supplies and were told by most of the suppliers that they did not know if an adapter would work or not

Strangely enough, last time I heard a lot of detail on R600, it was something to the effect of having a higher heat density (in nanometers) than a nuclear reactor.
Besides, what is the point of building that card for something that doesn't exist yet? You're creating even higher prices for the consumers, who are inevitably becoming more impatient with the delays. nVidia is in a major winning situation as long as ATI keeps dropping the ball.

 

[40sTheme]

Read closer, it says it includes both an 8-pin and a 6-pin, unless I read it wrong.
