9600gt Black Screen of Death Question

I'm posting it on the nvidia forums too.

The buddies I'm referring to are Del and Cruistix.

I do not own a 9600gt, but I’m planning on buying one.
One of my worries was the black screen of death that some people are having. The card will run flawlessly for 10 minutes sometimes, an hour other times, and then just go black and restart.
The literature I’ve read says the 9600gt has a power supply requirement that goes beyond just wattage. It has a 12v rail requirement of 24 amps.
Well, my buddy brought his in and let his friend try it on his computer. My buddy has a power supply with 18amp 12v rails. This is not enough power to run his card. The card ran fine on his buddies that had enough power.

Here’s my question…
The video card came with a power cable joiner that looks like it combines two molex 4pins together into a 6pin pci-e connector. I’m guessing this is so you can join 2 separate 12v rails from your power supply to get more amperage. Here’s a picture..

My power supply has 2x 12v rails with 20 amps a piece. So if I combine the 2 with the cable it came with I should have plenty of amps to run the card.

Has anyone experimented with this?
