  • Graphics card to power supply issue

    My 7950 MSI card has two 6 hole slots to be connected to psu.

    However out of my pus I only have 1 6 slot pin....its say pci-e on it.

    If I only connect 1 pin is that ok or problematic?

    If I need 2 how can I get another pin out my psu?

    Is there an adaptor to get 2 in 1 etc.

    What I have done and dont know if this is good or bad but i have a 6 pin connector with tow molex ends...I put that in the 2nd slot on the gpu and then from the 2 molex i have a 2 to 1 molex....the 1 end of this molex goes into the main psu molex.

    So what I have is

    gpu 6 pin with 2 molex>>>>2 molex to 1 molex>>1 molex into psu molex

    picture of cable...http://bigbytepc.net/images/molexpcie.jpg

    so really questions.


    1. Do I need to have both 6 hole slots connected?

    2. How can i do this with only 1 current 6 pin connector in my psu

    cheers

    You do need both to be connected, or else your graphics card will not have enough power to run.

    What PSU have you currently got? Brand and wattage?

    What is the rest of your system specs?

        I'm not sure that will provide enough power.
        Do you not have 2 spare molex connectors? Avoiding using the 2molex - 1 molex cable, as it will be drawing all the power from the one molex connector then, which I don't think will be able to provide enough juice.

        Which model of PSU is it specifically?

          Its HX520w http://www.trademe.co.nz/computers/c...-503042326.htm

          so you mean i should be putting the 2 molex leads into 2 seperate molex leads coming from my psu?

          but i dont even have that many molex from my psu...maybe only 2 or 3 tbh..and they are all used by hard drive, dvd drive etc....

          Added after 2 minutes:

          I do have a spare 8 pin addapter from my psu maybe i can get adaptor to make it 6?

              If you're using IvyBridge, how are you still using IDE drives? That kind of baffles me.

              I would look at a new PSU. I would not want to draw that much power through a single Molex connector, especially as it will probably hurt your 12v rail too.

                The HX520 Should have 2 6-pin pci-e connectors anyway "/ can you take a picture of the side of the PSU the ports are?

                    From a review site quickly pulled from Google:

                    • 2 x 21" cable for 6-pin PCIe connector
                    • 2 x 31" cable with three 4-pin IDE drive connectors
                    • 1 x 16" cable with two 4-pin IDE drive connectors
                    • 6" 4-pin IDE to two 12V only 4-pin IDE connectors (meant for fans)
                    • 6" 4-pin IDE to two floppy power connectors
                    • 2 x 25" cables with two SATA connectors


                    What've you done with the other cables? Why do you require an 8pin to 6pin? Your PSU has two 6pin PCIe power connectors and that is what your card requires.

                      ill need to put my pc off...do it later..if it has 2 ports does that mean i need to buy another 6 pin to 6 pin ci-e cable?

                        the 8 pin (if its the PCIE) might have two pins that detach, to leave you with a 6 pin, though I am not familiar with your PSU.

                          What've you done with the other cables?

                          NO idea i bought it from a guy who already built it...those were only cables in...he had only gf x card only needed 1 pci-e 6.

                          Can I buy new cables?

                            So you don't have the other cables which are meant to be supplied with the PSU? You probably can buy them from the Corsair shop but I had a quick look and they're about $8. Whether you can get them from the UK or not, I don't know.
