Not Really Windows 10 Per Se... Making a PCI-E 4-pn Power Connector

I have the parts...

I want to make C using A and B without **ANY** possibility of frying the video card..

I know it's likely simple, but I am talking a GTX TITAN 6GB Video Card and I don't want to have **ANY** possibility of frying it.. For reasons I don't really want to get into, buying one on Ebay or Amazon is not an option..

Help a brother out???

Yea, I hear ya.. But, because of circumstances both external and internal, it would be at LEAST a week (likely 2 or more) before I can order the connector..

Damn covid hysteria!!

And I really want to light this puppy up..

Figuratively speaking.. Not literally...

Covid-19? How would that affect online ordering?

However: the yellow wires are +12V, the black are grounds. That applies to both the PCI-E and Molex peripehera connectors.

The pinouts for the PCI-E connector are:



The pinouts for the Molex peripheral connector are:

Thanx guys.. JUST what I needed..

The covid comment was regards to my personal finances.. As I said.. LONG story..

Anyways, the videos and the pinouts are JUST what I need to do this with confidence..

Thanx again...

So, just to follow up...

I clip the red wire off of B and run all the yellow wires from A to the single yellow wire on B and divvy up all the black wires from A onto the 2 black wires on B..

And there shouldn't be any "load" issues or anything.. Right???

Do you plan to use two peripheral connectors per adapter? I see that the 6GB Titan uses a 6 pin PCI-E plus an 8 pin. I believe that both must be used.

The 6 pin is rated at 75W, so a single periperhal connector could supply all the current needed. (It's rated at 11A.) The 8 pin PCI-E is rated at 150W, so you'd want to play it safe with two peripheral connectors.

The power supply in the computer has an existing 6-pn connector I can use.. So I am good there..

When you say "The 8 pin PCI-E is rated at 150W, so you'd want to play it safe with two peripheral connectors." are you saying I should make a 2 4-pin molex connector (ala pic C) and plug BOTH into existing 4-pn connectors..

Sorry to be so detail nitpicky, but I just want to make sure I don't fry this Titan...

The PCI-E adapter that you need is 8 pin, not 4.

Yes, you'd want two use two Molex peripheral connectors to feed the PCI-E connector. There are 3 +12V pins on the PCI-E. Two would get 12V from one Molex, the third from a separate one.
