I have just received several of these cables and seem to be running into a problem not described anywhere else here.
If I have a card plugged into an adapted x1 ->x16 cable (plugging the extender into an x16 slot) the computer refuses to boot at all. Using a combination of sapphire 5850s and 5870s on a Crosshair IV Formula motherboard. This happens even if I am only plugging in one of the cards that works when plugged straight into the motherboard, so I am confident it isn't any sort of ATX power issue. I have tried with, and without, the pins shorted as shown in many of the diagrams here.
I appreciate any help or insight anyone here may be able to offer.
Thank you.
Hi Thor, some motherboards will boot with the 1x->16x adapter plugged into the 16x slot, however in many cases you would need a straight 16-16x cable. Send me an e-mail to
sales@cablesaurus.com and I can get a replacement in order if necessary.
