hopefully this will help out..........will stick to my 8800GT till pricing of the 285GTX will be on a reasonable level.if somebody wants to make his own cable here you go.....bought mine from apple directly.......
It turns out that the relatively-standardized PCI-e power connector on the 8800GT is known as a Molex male "Mini-fit Junior" type with 4.2mm pitch pins, so to make your cable you need a 6-pin female mini-fit connector for that end. Molex's part # is 39-01-2060 (39-01-2065 will also do.)
The power connector on the Apple mobo turns out NOT to be a custom Apple part at all, but is known as a Molex male "Micro-fit 3.0" type, with 3mm-pitch pins. You'll need a 6-pin female micro-fit connector for the mobo end of your cable. Molex's part # for this is 43025-0600. The round-cornered pins on the 43025-0600 fit the Apple mobo connector exactly so I didn't have to do any whittling on this one - go figure.
I also bought a few extra female mini-fit and micro-fit pins in case I screwed up the wiring operation; in the end, I didn't need them because I was super-careful with the crimping operation.
Get yourself about 3 feet of 22 awg yellow and another 3 feet of black wire to make a cable that's got the stock color coding of black ground wires to the upper 3 pins and yellow wires to the bottom 3. I connected all 6 pins even though I believe that the center pin on the bottom is a n/c. Trim your wires so they match in length as closely as possible so that no single wire recieves more strain than the others.
Without the proper crimping tool you'll have to strip and crimp the wires on the female pins "by hand" with a small wire-stripper and a good set of small needle-nosed pliers. Strip the wires carefully - about 2mm of exposed conductor for the micro-fit and 3.5mm for the mini-fit. You want the "outer" or posterior set of crimps on each pin to bend around and grip the INSULATION on the wires, for strain relief; only the inner set of crimps is used to make electrical contact.
Once all 6 wires are crimped at both ends, you can insert them into the connectors; like pins are wired together on each receptacle. Pay attention to which types of pins you're inserting into which connector - yes, the mini and micro pins are different! - and the correct axial orientation in each receptacle. When they're seated correctly you'll get a tiny but satisfying "click". Tug gently on them to make sure they're fully locked in the receptacle.
That's all there is to it, except for the tricky operation of getting the micro-fit connector aligned and plugged into the Apple mobo - tricky because the clearances are small and your hand is big. I actually used a pair of needle-nosed pliers to get the alignment between male and female connectors set up and then pressed them gently but firmly together with one finger until the mating toggles overlapped. Close the case, power up and you're good to go!
