Solved

Not to sure about my current power supply.

So I'm going to be ordering a new 680 but I'm unsure if my PSU can handle its power.

My current Psu: http://www.newegg.com/Product/Product.aspx?Item=17-341-018&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Page=2#scrollFullInfo

The gpu I'm buying: http://www.newegg.com/Product/Product.aspx?Item=N82E16814127693


Notice that the 680 is a dual 8 pin where as my PSU only comes with a 6 pin and a 6+2 pin connectors.

So the question is will I be able to buy an 8 pin Cable and connect it to the modular slot on the psu to replace the 6 pin or will I have to use the one 6+2 Pin cable and then use Molex adapters to get the last 8 pin?

Tyvm for the help here if you give any!

  1. New PSU I think. The 6-pin only provides 75w, while you get 150w from the 6+2 pin, so it's not just a question of cables. You could use a Molex adapter, but it's not generally recommended.

    So this means either upgrade my PSU or use mollex adapters.

    Or just get a 680 that is 8 pin + 6 pin?
  3. Or one with two 6-pins :-)

    Surprised a 700w unit only came with the 2 pci-e connectors, but it being modular u shud be able to pick up anoth 6+2,
    I agree w/ sam_pLay molex adapter will prob work, but i wouldn't do it.

    So for sure if I bought another 6+2 pin connector I could use it on this PSU and have 2x 6+2 Pins in the PCIE slots on the PSU or will one port put out less power than the other one?

    Hi again - Have you purch the GPU yet? MSI offers and may include a 6 to 8 pin adapter in the box, so you may not have to
    purch another cable. As far as the power being divided, you need to check your PSU's 12v rail or rails amps. On a 700w unit
    you should have plenty, but either look on the PSU label or booklet. If this is a quality PSU, you'll gave plenty of amps
    avail to run that GPU (& possibly 2 of em)

    No I have not bought it yet and it doesn't come with the cable I need.

    here is the chart for my PSU (its the 700 series) I'm not able to make sense of all of it.

    Hi again - MSI should furnish that adapter cheaply I would think, if not it's prob avail
    at Newegg.
    Not to worry - you have 50a & 552w avail on +12v rails and even tho it would be
    nice to have a little more of the total on the +12v you will be able to run that card.
    I read somewhere that it draws about 316w on average during game play.

    Tyvm for all the help. I wanted to just be certain I could run the card on this PSU if I bought another 6+2 pin and replaced the other 6 pin connector.

    I mean for $500 I want to make damn sure I don't have to do anything else. I plan on Over clocking a little somewhere around low 1200Mhz for core and the boost in the high 1200s so sounds like I have plenty of power for it.

    You should be happy with the performance you're gonna get.
