How use a 6pin molex adapter for hd 7770

My computer is an Inspiron 620 and the PSU is only 300w. Now I have the graphics card in the slot but I don't see WHERE to put molex adapter into. I don't see where there's holes for them, and I really won't be able to get 40-60 bucks for a PSU soon either, well by soon that means a month or two, I just really want to try it out already.

So yes I could see where to plug it in on the graphics card but I just don't see where to connect the other two parts, I don't know how to post pictures on here, but I might make some imgur account later to show. And I've been searching for the answer for about 20 minutes.....I kinda feel stupid asking it, maybe my motherboard doesn't have the holes? Idk just help quick, I'll check this most likely tomorrow

  1. You need two free four-pin Molex connections from your Dell PSU, which would be the match for the two pig-tails coming from the six-pin PCI-e power adaptor. It is very possible that Dell does not have enough, or any, four-pin Molex power connections on the PSU in your system.

    If that is the case, there are SATA to Molex adaptors available: http://tinyurl.com/o8443ls
  2. I got it opened up now and putting photos up on imgur, hld on
  3. Also upload the pic of your motherboard and the all the wires that are coming out of power supply.
  4. well my camera kinda sucks today http://bobbflocka.imgur.com/all/# need more?
  5. Your pictures are not publicly appear.
  6. Alright I think I'm just going to go with getting a new PSU, I just really want to know if I won't miss some connections or it won't fit, how do I figure that out? I kinda like this one, but I don't know if I'll be missing cables and such http://www.newegg.com/Product/Product.aspx?Item=N82E16817148027
  7. Can you tell me the exact make and model of the graphic card. I mean company and and whole name not just hd 7770. Those IDE connections are seem a little off. Also i need to make sure your power supply have right molex connectors for your graphic card.
  8. Yeah get that power supply. It has 6 pin molex connectors for your graphic card.
  9. DO NOT get that PSU!
    It is a poor quality unit and lacks decent protection, this is a better unit by far: http://www.newegg.com/Product/Product.aspx?Item=N82E16817256060&ignorebbr=1
    Don't worry about its 'low' power, it has plenty of juice for your system, the card makers overstate the cards power requirements specifically because of poor quality power supplies!

    BTW the IDE connectors you're saying, your knowledge is wrong. The Molex connectors are the ones you're calling IDE, and the ones given in this image are SATA power connectors.
    IDE connectors are connectors used to provide data interface to older hard drives, with Molex as the power cables for those drives.

    Probably, but it's a poor quality unit. Please do not make such suggestions.

    Ok, look when I bought the graphics card, it was like if I just gambled, how would I know the PSU is "compatible" and/or has the enough cables and/or fits in my tower. I just the suspense and when something didn't seem right, but yes I'll go for this one instead of the other one,

    Sorry, just got home from work and it would appear I just about missed all the fun. :-)

    I don't like the term IDE power, and recommend it not be used, as it isn't correct and can lead to confusion or misunderstandings.

    This is a 4-pin Molex connector:


    This is a SATA power connector:


    This is a 6-pin PCI-e power connector:


    For the power adapter to be used with your graphics card, you need to locate two 4-pin Molex connectors, and plug them into the adapter. They really won't be too hard to find. Just trace the wires that come from the power supply. If you can't find the Molex connectors, you are left with the option of adapting a SATA power connector for use instead. The other alternative would be to purchase a new power supply that has the correct 6-pin PCI-e power connector for your graphics card. The ideal solution is to buy a new power supply, but when a new PSU is not in the budget, you may be able to afford the adapter route. I looked a little further, and because of the low power requirements of an HD 7770, I would actually suggest just using this adapter:

    http://www.newegg.com/Product/Product.aspx?Item=N82E16812816315

    It will adapt from one of your SATA power connectors, directly to your graphics card. Just make sure the 8" length is long enough to reach.
  13. But aren't the molex connectors use to power old HDD (not the SATA one). How they can be used as pci-e power connector?
  14. While 4-pin Molex has been used prior to, and during the transition to SATA power connectors, 4-pin Molex power has been used for other devices as well. The power connectors don't necessarily deliver magically different power from one another and can be adapted safely, provided you don't exceed the current capacity of the original conductors and plugs. That's why you generally see 2 pig tails on a 6-pin PCI-e to 4-pin Molex adapter. They all tie back into the same power sources inside the PSU. The reason for the different sizes and shapes of each connector is to make sure the end-user plugs things in correctly, so that power limits for wire conductor sizes and connectors are not exceeded, and for example in the case of SATA power (notice the staggered conductors,) so that grounding takes place before signaling during a hot-plug.

    In the case of the OP's HD 7770, the graphics card only maxes out near 80 watts of power, which is just shy of the PCI-e standard 75 watt capacity, so his adapter is not going to be carrying much of a load.
  15. I'm not going to put under load, maybe the only times are if the enb mods work for Fallout NV, but I was thinking about the SATA, but I have two pigtails, and yes I did see two free sata's* it'll definitely reach it. But this one just requires one, kind of worried.
  16. Nah, with an 80 watt max TDP, the one SATA to 6-pin PCI-e will work fine. The PCI-e slot on the motherboard should be able to provide up to the first 75 watts, if you have no other PCI-e peripherals installed, but any way you slice it, the adapter won't have much work to do with an HD 7770. If you were planning to run a higher wattage graphics card, I would definitely not recommend the single SATA power to PCI-e adapter, but then, you'd probably have no choice but to be purchasing a larger PSU anyway, which would already have a proper 6-pin PCI-e connector. :-)
