I have just recently bought an Asus nvidia GTX550ti direct CU. it has an auxiliary power connector. does this need to be used or does it not matter unless im doing a sli??

More about : question

When a card has a connector like this, it means it needs more power than the PCI-E bus can deliver and it is required. But this should also be stated among the installation notes on your manual.

6 pin connecters are required to be connected(some double 6 pins may not need the second one, but all single ones will need it). The only time this happens is when someone try to cut around the corner and did not question their psu if they can run X card yet.

It does matter SLI or not. Why are you asking? Don't your PSU have the auxiliary power connector cable? What is your PSU?

Im assuming you are using a 6 pin connecter to 2 4-pin molex convertor that gpu companies usually give to you. you can use that, but if your psu doesnt have one built in already, than its likely that it will not like being connected tot he card because it was not designed to power up a gpu.


to your question. yes, both must be connected to the molex cable off your psu.

so does that mean that the card is working at minimal performance because its not hooked up correctly because its working for me to talk to you all right now. so ultimately i really need to upgrade my psu?

PCIe connectors sometimes come in 6+2 configuration. If your graphics card only need 6PINs, you just leave the +2pins dangling. No problem with that.

It is always good to get an upgrade to a known & well trusted brand. But based on your statement below:

then we know at least that the PSU can handle during idle. The real test is when you start gaming. Have you tried that yet & did you encounter any problem?

Then I guess it is just a matter of "if it ain't broke, don't fix it".
