trouble installing my 560 ti

post #1 of 36
Thread Starter 
The card requires 2 6-pin connectors from my power supply, though I only have 1. I don't know much about that aspect of video cards and it didn't come to mind that it might be a problem. It came with 2 power connectors that I can connect to cords coming from the power supply(think its called molex?), should I use that? I googled it and got a couple websites saying it should not be done that way, whats the difference? Another thing I noticed, the connectors that came with the card have a pin missing in both the side that connects to the video card and the side connecting to the power supply. Should I still be using the one power connector already in my computer since it isnt missing it, or should I use both that came with the card. Something I'm confused about aswell, is theres 2 molex connectors attached to the 6 pin connector, do both of those need to be connected, meaning if i use both the connectors that came with the card, I'd need 4 of those connectors from the power supply? Sorry I know its a lot of questions.

Yep - use the molex connectors. They are provided for people in you situation.

Yes, you can use one of your PSU cables and one molex connector if you wish. It doesnt really matter as long as the card as both power sources installed.

Using the molex connector is the only option to power your graphics card That isn't buying a new power supply.

The molex connectors are just fine as long as you don't overclock your graphics card, If you want to do that then You'd need a power supply with two 6 pin power connectors.

I know some cards already come overclocked, mine says free performance boost on it, would that be a problem? And if I did try and overclock it with it connected this way, what would happen?

I wasnt aware of this. Granted the PSU indicated is staed 500w - unknown brand. The system doesnt look all that power hunger either.

The GTX 560 Ti doesnt pull that many watts, even at full load. Id suggest the OP could get away with a modest OC if the card is properly supplied via molex. Im mean, its not like he is going to SLI thye cards...smile.gif

Not sure what that means by a free performance boost... I dont see an issue.

The worst you can expect is crashing to desktop, BSOD and unstable OCs. Try a modest OC and see how it goes.

Id suggest your next upgrade be a good PSU. They are the life force of your PC and will serve you well into the future.

Nothing much would happen if you had the molex plugged in. It is just reassurance. I wouldn't overclock it any further. If it is factory overclocked then it is stable and will run on either a molex or real 6 pin.

@ above got ninja'd.

no, That would not be a problem.

The problem with overclocking with a molex connectors providing power is that the molex connectors can't supply enough power to properly power the card, resulting in crashes.
or so I heard..............

Does it matter which molex connectors from my power supply I use, can it just be any combination of them? I heard they should be from the same rail, though I don't quite know what that means.

Don't stress about it. Leave it as it is. Christmas is coming. Get a new PSU and maybe another GTX 560 Ti and SLi them.
