  PSU 2 24pin power cables 
 Date Written

I have a Dell workstation 490 that has 2 duel core CPU's on the mother board. The computer came with a 750W power supply (model N750P-00) that has two 24pin power cables required to run this computer. I'm trying to upgrade the graphics card however and recently purchased a GeForce 670 FTW.

This card seems to requires 2 PCI-E power connectors (my PSU only supplies one) from the PSU and demands more power than my current power supply provides.

I thought this would be a simple issue and went to Frys to buy a PSU with two 24 pin connectors and the power I needed. They didn't have any. So I came home and started looking around online for a PSU that would work. I can't find one. I called dell, they don't have one.

so, what can I do? I'm running out of ideas. is there a small aux power supply that would fit into one of my computer's device bays that could supply my GPU with power on it's own?

I don't have much room in my case and adding a full secondary power supply is probably not possible.

thanks in advance for your help and suggestions.

could I purchase a PSU with the necessary power and use this cable:

to branch the power from the PSU to the two connectors on the MoBo?

this site seems to have it available:

I am not sure how to answer your question but I think it will not work as you need two plugs with enough power; your solution may not give you the needed power.

Sorry I could not help you any further.

Best of luck,
