PCI-E 6 pin to molex

Hey, this has been driving me crazy for a bit and i cannot find out the answer. Hopefully you guys can help!

Awhile back ago I've purchased an eVGA 8800gts. It supplied me with 2 PCI-E Power adapter. The adapter was split into two giving me two molex connector going into one 6pin PCI-E. So when I hooked the PCI-E power adapter to my video card I only plugged in one molex to the adapter and left the other one unplugged. It's been running like this for about 2 years.

Would this cause any issues? I've heard you need to plug in both molex from the adapter to get enough power to the video card.

  1. It is recommended to plug 2 molex in to supply enough power apparently your PSU has enough power on that rail not to create issue.

    it depends on the card, I ran both a 9600GT and 9800GT with just one plug in but both don't need a lot of power. If there has not been an issue in two years, then there is no need to change now.
  3. Thank you both for your input. I can finally put my mind at ease.
