Question sli psu plugins

I have a older nvid board ( 680i)that can run tri and I would like to try to run two cards in the future but the thing is that my PSU is a real power pro 750 standard which I am pretty sure can handle SLI but it only has two 6 pin and two 8pin connectors and the 8 pin connectors are attached to the 6 pin connector line. now most video card need two plugins in a few different combinations two 6pin or an 8pin 6 pin.anyways how do I run two cards?

If I understand you right, you're saying that your PSU came with two 6-pin and two 8-pin modular PCI-E cables but the PSU itself only has space for two PCI-E cables of any kind? If that is the case, you'll just have to use molex to PCI-E adapters to make up the extra connectors you need. Of course, it also depends which GPUs you plan on using, but most newer nVidia cards do require two PCI-E power connectors.

If the 6-pin and 8-pin connectors are on the same cables, they can still be used at the same time in which case no adapters are necessary.

That depends on the video card. Some cards require one 6-pin and one 8-pin and others require two 6-pins. And depending on how the sockets on the card are located, you may be able to fit an 8-pin connector into a 6-pin socket and leave the extra two pins hanging out if there is space.

Get a PSU with the appropriate number of PCI-E connectors....
