View Full Version : PCI-Express 2.0! More power and still extra power connect?

02-28-08, 11:20 AM
One of the advantages of the PCI-Express 2.0 was able to do more power to the video card, so... why I need to user the extra power cable 6/8 pin to the vga?

ex: 9600gt or 3870

The majority of users will be using a these cards in a 1.1 slot, so they will still need to have the other connector to use the card. There are not a lot of motherboards out that are PCI-E 2.0 capable.

Agree but and how have motherboard x38/x48 for exempl?

Can I use a 9600gt without auxiliar power on a Intel x38 board?

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.

Why not just try it? The worst that will happen is either 1) the computer won't POST or 2) you'll get a pop-up warning at bootup or within the OS saying that the power isn't connected. You won't do any damage to the card or your system.

2.0 is backwards compatible.
If you're using a 1.0 card or cards, you don't need an extra plug.

As far as I know.
Google search it.
