PSU/GPU power compatiblity

[Jake Rose]

So I recently bought a new PSU and a New GPU to put in SLI with the other one. The GPU is a EVGA 760 and the PSU is a EVGA Super Nova 750W. When I was installing everything I noticed the PSU only has enough connectors to run one card. This is what the pins look like for the card. Do I have to have power going to both the 8pin and 6 pin? I only have an 8 pin cable to run from the PSU.

So it has an 8 pin and 6 pin connector? You need cables to both.

Yes you need both plugged in. It looks like your PSU has connectors for 6+2 pin power so you take off the two pin and you'll have a 6 pin connector you can use. You should have plenty of power for your build with that PSU

You have to have power plugs in all of the pins in both cards. You can use molex to pci adaptors but you are better off with a power supply that actually supports the cards.

You'll probably need something like this: http://www.amazon.com/PCI-Express-Y-Splitter-Adapter-Converter-Gaming/dp/B004PBJARO

Or another PSU as suggested above.

I will probably send it back and get another. I don't understand why it is advertised as SLI ready if its not completely SLI ready. http://www.newegg.com/Product/Product.aspx?Item=N82E16817438025


Anything you recommend.

it IS SLI ready. Go through your cables you will have a 6 pin and 8 pin connectors, if they are no native 6 pin they will be 6+2 where you can detach the two from the 8pin cable to make it 6 pin.

Your conncections:
24 Pin ATX: 1x
EPS (CPU): 2x 8pin (4+4)
PCIE: 3x 8pin (6+2)
SATA: 9x
Four-Pin Peripheral: 5x
Floppy: 1x

Those 2x 8 pins are (6+2) so you just take the two off from the end and voila~! a 6 pin connector.

Oh there are only 3 of them I see. Looks like you might need to return it. If you can go for a PSU that has a single 12v rail on it.
