Hi,
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
<o:p></o:p>
I have a question about making my own 8-pin PCI-E connector for the HD 4870x2.
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
My CoolMaster RealPower has 2, 6-pin outlets and 2, 8-pin outlets for the PCI-E.<o:p></o:p>
Look at link to understand.<o:p></o:p>
http://www.alternate.nl/html/product...r+dan+600+Watt<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
The cable that came with it has a on one side a blue PCI-E connector and on the other side a 6-pin connector.<o:p></o:p>
<o:p></o:p>
For some odd reason I only have one adapter cable being a 8-pin connector but has 2 empty slots, so in other words is a 6-pin connector with options.
<o:p></o:p>
<o:p></o:p>
Still with me?
<o:p></o:p>
The Sapphire HD 4870x2 on the other hand came with a, on one side black 8-pin PCI-E connector and on the other side a standard (male) flat 4-pin white Molex connector.
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
Now comes the technical questions and what I did so far.<o:p></o:p>
I took the PCi Express connector that came with the PSU, cut off the 6-pin PCI-E connector from the bottom end and added 2 wires to the blue connector to complete the 8-pin's PCI-E connector.
<o:p></o:p>
I also cut off the 2x 4-pin white Molex which came with the HD 4870x2 adapter cable at one end leaving me with the 8-pin PCI-E connector.
<o:p></o:p>
<o:p></o:p>
So now I have a blue 8-pin PCI-E with loose wires and a black 8-pin PCI-E with loose wires which I intend to connect via a bridge.
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
It looks like this, where the * is a pin.

4 | * com | * com | 8

<o:p></o:p>
<o:p></o:p>
I hope you're still with me...
<o:p></o:p>
<o:p></o:p>
Going from there, I connected the black PCI-E connector (HD 4870x2) the same way.<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
Now the question before I connect the lot....
Is it as simple as I think it is....?
Do the wires have a specific place into the connector?<o:p></o:p>
Just add 2 wires to the one connector and attach the other connector via a bridge in the same order, in effect make an extension cable..
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
I wanted to test the theory by trying to connect the blue PCI-E connector to my HD4870 and the black PCI-E connector to my PSU (all without power obviously).. <o:p></o:p>
it should work.
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
Thx for any reply regarding the rather long post.
<o:p></o:p>
<o:p></o:p>
Edit:
CHANGED ALL MOLEX'S TO PCI-E ... KINDA GOT LOST IN THE MASE OF CONNECTORS.
