Can an Antec BP550 550w PSU run two GTS 450s?

I know the wattage will be enough to run the two cards in SLI, but I was wondering, does the PSU even support SLI? I still have all the cable that came with it, but I'm confused as to what I must do. There one 6-pin PCI-E power connector that is running my one GTS 450 at the moment, but when I upgrade to two, what connector do I use? The only the 6-pin connect that came with it that seems would be compatible is a strange one with one of the end of it being red. Is that the one I use?

There is one 6-pin PCI-e connector that is part of the built-in cabling, along with the 24-pin power connector and the 4+4 pin CPU power connector. But there is another cable that look like it would power a GPU in a PCI-E slot. It looks like this:

When I install the second GTS 450, is the power cable I use?

can you post the name and model/numbers on side of psu.

without seeing this the only advice we can give you is to buy a psu that we know has the right cable.


didnt read the title

yes it can run it.

your psu has 3*12v rails that give max power at 264.

should be fine
