GeForce 9600 GT, power supply questions around 12V rails? - 2008/05/30 20:18
I saw this topic touched upon a little in another thread, but the guy couldn't speak English very well and I think a lot was lost in translation. I do not own a GeForce 9600 GT, 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 GeForce 9600 GT has a power supply requirement that goes beyond just wattage. It has a 12V rail requirement of 24Amps.
Well, my buddy brought his in and let his friend try it on his computer. My buddy has a power supply with 18Amps on the 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 4-pin molex together into a 6-pin PCI Express connector. I'm guessing this is so you can join two separate 12V rails from your power supply to get more amperage.
My power supply has two 12V rails with 20Amps a piece. So if I combine the two with the cable it came with I should have plenty of amps to run the card. Has anyone experimented with this? And just so you know my power supply is one from BFG, namely the 650W standard version.
