NEED URGENT HELP.....can this be done?

post #1 of 10
Thread Starter 
my new rig didn't have enough power for the 8800,so i guessed i could take it from the main rig's PSU.
the other psu has 45A on the 12v rails and can take 2 8800gt/gts 320.
but the second PCIE connector cable isn't long enough so it doesn't reach the GTS's pcie connector
EDIT: i managed to connect the 2nd PSU PCIE cable into the card.

I'm so confused...Are you trying to use a second power supply for the 6pin connector for your other graphics cards?

I see what you're doing. And it wont work. You might fry the GPU. It would have to be turned on at exactly the same time. BUT it would have to be turned at the exact same time. Not even a nano second apart. Anyways, what I'm trying to say is. It COULD be done. But not humanly.

It is not safe to use a separate power supply to power that second vid card without a connection to the mobo as voltage is running through the PCIE slot as well, and power from another PSU not tied in with the one connected to the mobo is bad, as it will fry everything and possible cause a fire. I suggest you get a better powersupply.

Yeah, like other people have said. I'm sure it can be done but its in no way safe.

Would be a good idea to start looking for a new power supply
