    I am looking to get a new power supply. I am in need of one that has 40 amps on the 12V rail. If I look at a PSU specifications chart like the one below does when using two of the 12V rails combined will that be 40 amps? The video card has a 6 pin connector and an 8 pin connector. The 8 pin connector from the power supply is on the +12V4 rail and the 6 pin is +12V2.

    1. How did you determine that you need that 40 amps on the 12volt line?
    2. That spec sheet is a little confusing to read as to the intent of total current capacity. I would read it as being 20 amps on each
    line BUT......
    3. Who is the manufacturer? I would double check with them. It just doesn't look like a "standard" spec sheet and some companies do not always comply with standard coding for their products. That's not saying that they aren't OK, just depends on who wrote the sheets. Go to the source for the right info.

    Sorry, about the long post back. I did not have access to a computer for a couple of weeks. My old power supply finally failed. I have a new one installed now. I decided since I was replacing my PSU that I would treat myself to a nice video card. I just wanted to make sure I got the correct power supply for it.

    1. The video card maker list it in the specs, but they did not state that using two separate connectors at 20 amps each, if that would get the 40 amps that I needed.
    2. You are correct, it is 20 amps on each, I was not sure if you used two separate rails would it equal the 40 amps needed. That would be a yes for me; the video card has two separate connecters for two different rails to connect too. Using those combined will cover the requirements for the video card.
    3. Thanks, I did go for the source. I did not have a computer to see the posted back I had an idea and called the manufacture. The spec sheet for that power supply shown was OCZ, I ended up getting one from Kingwing.

    Thank You for the input.
