As the title said, I got some doubts about my PSU 12v Rails. I want to understand what the info. description of my PSU say. So here it is:
It said that it got a +3.3V (24A), +5V (20A), +12V1 (20A), +12V2 (25A), -12V (0.3A), +5VSB (2.5A).
Now, my question is about the video card that I buyed. It's a AMD HD RADEON 2GB 7770 and everyone say on forums that with a 450 or 500 watts PSU it's ok. So, I got the original the PSU that came with the computer of 500 watts, and, the max 19A that I need for the 12v for my video card. What I want to know is the difference between the +12V1 amperage and the +12V2 amperage, and wich one I need to use?
PD: If it's a dumb question then I'm sorry. I'm still learning about this things. Thanks in advance.
