if you don't have a nother pci connecters you will need to get a molex to pcie to add .

if that is the psu you should have more pice connecter . it's a moduler psu so you should have them lying arround some where. check the box

That 1250W PSU has provisions for at LEAST six 6+2 PCIe power connectors. Your original box should have come with more PCIe power cables, you're going to have to find them or buy replacements from Seasonic support if you threw them out or lost them. The cables plug-in to the PCIe connectors on the PSU .... the ports are clearly labeled as such.



For the sake of clarity, please don't refer to those plugs or sockets as "slots" - a "slot" is the PCie x16 card edge connector on your motherboard that the video card goes into. If you refer to the word SLOT, most people will think you're talking about that type of connection, not a power connection.

There is no benefit from using more than 1. And you can install on either bridge location, doesn't matter. The SLI bridge only helps take some stress off your PCI-E ports by using that bridge to communicate between the cards instead of over the PCI-E, improving performance. The cards will only use ONE bridge though, so having a second installed it will just ignore the other.

If you have two GTX 680 - you only need one bridge. The second bridge connector is only utilized if you go Tri-SLI or Quad-SLI. It won't hurt to have a second bridge cable on there, but it will not be used.
