i want to connect my radeon HD 4870 GPU , which has 2 X 6 pin PCI-e connectors required to OCZ600MXSP PSU which has 2 X 8 pin outputs...

i have all wires and plastic connectors for them to sleeve my self, i just want to know right pin out sequence .
does someone know or have this cable and just could tell me p1 to p1, p4 to p6 and so on....?

So what is wrong with the leads from the PSU now? That PSU has a 6pin and a 6 + 2 pin. The 6+2 is able to be split to use as a 6 pin.

i don`t have any original leads for my OCZ ,i want to make them myself, instead of ordering or buying.

i want to make a cable myself :

6 pin ...
G(p4) sense(p5) G(p6)
+12(p1) +12(p2) +12(p3)

to

8 pin...
g(p5) g(p6) g(p7) g(p8)
g(p1) +12(p2) +12(p3) +12(p4)

i just want to know :
which wires should go to which wires between these two connections, like :

i assume for my OCZ it could be like this:

6 pin (p1) to 8pin (p2)
6 pin (p2) to 8pin (p3)
6 pin (p3) to 8pin (p4)
6 pin (p4) to 8pin (p6)
6 pin (p5) to 8pin (p1) ... this one seems have different one to manufacturers, so i only think it could be like this from picture above..
6 pin (p6) to 8pin (p8)
