Dell Precison 490 - PSU

HI All,

Can I please ask if anyone has any experience with using SATA II connectors and converting them to a molex connector?

I have seen a few people putting high end graphics cards into the Precision 490 machines but the current OEM PSU has only one 6 pin supply for graphics cards.

I suppose there is two questions here, (1) will what i am asking work? and (2) if so, has anyone done this and what card are you running? :bounce:

Many thanks

Haph

  1. Well, molex is a power connector. I am not sure if SATA would be a good choice with GPU, due to power regulation problems.

    Are you looking to be able to use a molex to pci-e adapter ?

    You can use a sata to molex adapter
    http://www.amazon.com/Supply-Connector-Adapter-Changes-adapter/dp/B001V9S088

    It's more expensive than one of these

  3. Those precisions come with a nice 750 watt unit , but like you found out connectivity is not there for a High End GPU.

    Like Dell suggest use two of these.


    Then use the molex to PCIE adapter I do not recommend using a SATA to molex adapter and then use another molex to PCIE adapter this will create way to much resistance and could be bad for your GPU if the voltage drops too low. If you are handy you could just cut off two of the SATA connectors and splice in another PCIE line this would be the best way if done right.
  4. could just run a 4 pin molex splitter like this:

    just a molex y adapter for 4 pins
    not sure if that is what your trying to do
  5. Thanks for the responses All, these are helpful and I shall be buying the molex adapters.

    Cheers!
