I am at a standstill for where to connect the additional PS connection for my new GTX 660. Did lots of homework before buying it, etc., talked with Nvidia Support, but still don't know. I have a Gateway FX 540S, with existing Nvidia GeForce 8600 GS. PCI Express. It has a 700w PSU which I thought would be ample for the new card..specs for computer...http://reviews.cnet.com/desktops/gateway-fx540s/4507-3118_7-32815138.html.
I installed the new card no problem but don't know where to connect the additional PS connector. There is a vacant 4 pin male connector nearby with outside red and yellow wires, with 2 black wires on the inside. The Molex adapter that came with the new card is a six pin on the card side, and the two connectors coming out of it are female with 3 wires each, outside yellow and brown & one black in the middle for each.
The Nvidia Support person said I needed a LOGISYS AD201 12v Molex to 12V 6Pin Adapter to make it work. But what about the second connector? Do I just connect one and leave the other unconnected or get a pass thru to connect both? I called Gateway to find out where to connect, but they couldn't help, and did advise not connecting it, to which I can understand their position.
So, I am at a loss and I have spent a day trying to find an answer. Certainly don't want to chance creating any problems without knowing what I am doing, and now I am wondering if my PSU would need to be replaced just to accomodate the new card. Wouldn't think so, but at this point I am frustrated with what I though would be a simple project.
Appreciate any help.
