No need, I reiterate that the GPU would be the bottleneck not the adapter or connection.

The PCI-E slot provides 75 watts of power and upto 16 lanes of bandwith, some cards draw more than 75 watts and need more from the PSU via a connector.

Bandwidth provided by the PCI-E slot is so high that no modern card, no card ever created for that matter can be hindered by the 16 lanes provided.

The x1950XTX in its AGP form was compared to its PCI-E counterpart and performed exactly the same, thus even that high powered card was not hindered by 2 gb/second AGP connection, PCI-E is 8 gb/second.

excellent points...well taken...but really it all comes down to one thing: i cant get enough power to my 8600gt from my vmod and there are no external connectors

Umm suck it up? tough luck?

it doesn't draw enough power for a supplemental PCI-E power connector, so you are already limited, same with the 7600GT, you might be able to.

So have you already volt modded it?

If not then how do you know it will draw more than 75 watts? Plenty of people have volt modded 7600GT's and they don't need a supplemental power connector; given that the 8600GT is close in power to the 7600GT does it really draw that much more power?

maybe they dont have the same mobo as I do...ECS C-19A Sli

It is an industry standard that the PCI-E alot provides 75 watts of power, if a card needs more the PCU gives it to it via a PCI-E 6 or 8 pin connector.

No motherboard is unique in the voltage it gives everyone gives the same (give or take a fraction of a watt) no ifs ands or ECS motherboards. Heck your motherboard supports SLI so it has 2 PCI-E 16x slots providing those 75 watts.

http://www.guru3d.com/article/Videocards/326/7/

"The design is clean and simple. A single slot fan will cool down the card. It's audible, yet not at all too noisy. Since the card will consume roughly 68 Watts when it's peaking it can draw its power from the PCI-Express slot, which maxes out at 75 Watts. So there really is no need for an external PSU connection."

so it draws less than an additional 7 watts when they are volt modded.

while the 8600GT:
http://www.guru3d.com/article/Videocards/427/4/

"A clean, pretty looking design. The 8600 GT cards have quite a low power draw due to the lower clocks, roughly 45 Watts. So here we do not see a 6-pin power connector. Which quite honestly I would have liked to see... why ? Because it's good for overclocking."

look at that, a 7600GT draws 69% more watts than an 8600GT, and the 7600GT has been well known to overvolt quite well. They say the extra cable is uesful for overclocking, but if the 7600GT can be heavily volt modded so can the 8600GT. Many members of this forum have heavily volt modded 8600GT's to prove it.

I still don't get why a second PCI-E (not PCI-ex, which can be confused with the wholy incompatable PCI-X) would be desired for more voltage" it would be much easier to rig up a PCI-E power cable than to arrange another PCI-E device to plug into the 8600GT.

point taken...thank you for your help, and this stuff is news to me

I just read about your volt mod, very nice work! I definitely don't have to balls to try something like that with a brand new card!
