So the graphics card that came with my prebuilt machine crapped out on me, and I need to get a replacement. I'm looking at the EVGA GeForce GT 730 2GB which should be plenty for my needs (not much gaming, some Photoshop/Lightroom use). The problem is that I'm not sure if the power supply can handle it. The card says it requires a minimum 300 watts and a "minimum of 20 Amp on the +12 volt rail". I have no idea what this means. I googled this spec and found a lot of explanations, which I only kind of understand. One thing I found said that to find the number of amps, I would divide the number of watts actually supplied to the 12 volt rail by 12. It appears that this one has 360 watts going to the rail, which would give me 30 amps, right? If that's really all there is to it, it appears that there should have no problem. But how do I know if my power supply can handle this card with my other components? I don't have anything crazy, just a couple of hard drives and an optical drive. I'll attach a picture of the label on my power supply, if anyone can help me figure this out I would greatly appreciate it.
