Splitting a PCI-E connection

post #1 of 11
Thread Starter 
Hey guys,

Last night I installed a new 5850. I didn't realize that it needed 2 PCI-E connectors, however, I misplaced it. So I went out to microcenter and found a cable that splits the PCI-E connection. I wasn't sure if it would work since I don't know how much power one cable could draw. Then I tried to find a graphics card that uses around 150w like the 5850 does. I noticed that the 8800gts also uses only one PCI-E connector and draws around the same amount of power. Therefore, if the 8800gts can use one cable, the 5850 should be able to use one cable split into 2 correct?

Here's info on my power supply, 3-12v rails with 38amps:

Your PSU doesn't have two available molex leads?

uhhh, SOL?

I would NEVER split pcie power to a card that was made for two. If it could safely run with one it would only have one. Only option is to get more molex cables or splice off of an existing line that's not the pcie one.

Post me the model of your PSU. I probably have extra cables in my lab destined for the scrap bin... Yours for postage.

LOL! I guess I could have just looked in your system specs...

Checking now, but I am pretty sure all of the Antec PSU's use the same cables.
