Molex to 8 pin PCI-E Adapter missing pins

[fawal_1997]

Hi everybody 😀 ,

I have just taken " 2x molex to 1x 8pin PCIE power adapter " from a friend who has a Gigabyte GTX 970 ( the adapter which came in the box with the 970 ) ,
but I found that it only have 6 wires and 6 pins and two pins are empty , checked the web and all pics with 970 have the same adapter ,

SO , is it normal to have only 6 pins for an 8 PCIE power connector ?

NB : I need these adapters to power my Sapphire 7970 GHZ Edition

could be damaged or even mistake at the factory?...


anyways it is not a good idea to use such adapters at all

especially with high power consumption cards with weak no name power supplies without the proper pcie cables

what is the make and model of your power supply?

8pin pcie only use 6 pins. The other blank pin slots are purposefully blank. The gpu uses the blank spots to determine if the connector is correct 8pin and not 6pin.

Nice psu choice, but for the price, this psu still can't be touched.

And to reiterate: Never skimp on the psu.
