5970 power cable??

Hi guys,

I was about to install a second 5970 in my system, but realized that my 4 gig 5970 uses up both 8 pin connectors..
do i need to get a new power supply to be able to pop in my 2 gig 5970?

the 2 gig version only needs one 8 pin and 1 6 pin..

my power supply is a 1200 watt and has the power cables that can get unattached.
is this something I can buy at a pc store? like microcenter?

Id hate to think I need another powersupply.

Not sure what happened to the cable though..

any ideas?

thank you
Phil

  1. you just need something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16812706017 that is for the 8pin one they also make 6pin ones
  2. Your 1200W power supply is sufficient enough. if of course it's a proper brand with the right power ratings. :)
    Your PSU should have the sufficient connectors on it , I guess if it's not too old.
    If it doesn't then you need to get a power adapter from any of the online shops or your dealer that will comply with the power requirement of the 5970 and provided that you have the other power cable free from your PSU for it to comply with.
  3. You do not need the power adapters. Just use one 8 pin (6+2) and one 6 pin each.

    I do not know where the original specs for the PCIe power cables came from, but look at the 6 and 8 pin connectors. The 6 pin has 3 hot (yellow) wires and 3 ground (black) wires. The 8 pin has 3 hot and 5 ground wires. So each will carry the same amount of current through the 3 hot wires.
  4. I'm still curious as what make/model PS he's running???
  5. I think this is the machine he's using
    Alienware Area-51 ALX (Intel Core i7 950 1200GB/6GB)
    I don't really have an idea as to what Alienware uses for their PSU's.
