look at it this way, 23 amps is equal too 276 watts, you'll have a hard time running any GPU on that PSU unless it has multiple rails.

Ok in very simple terms when a PSU has multiple rails it means that it splits up the power into two or more parts adding up to a more powerful PSU. They do this because back in the day they thought it would be unsafe to have to much power in a PSU so that's how they did it. On the label on the side of the PSU look and see if there's more than one 12v+ rating. Or try to find the model and make of the PSU.

If you try and run a GPU that takes more power than the PSU can handle it simply won't work, depending on what GPU your looking to buy will determine how much power you need in a PSU. Here is a good quality PSU that I have a feeling you'll end up needing before you can upgrade your GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E168... (if you look at the close up of the sticker you'll notice that this particular unit has 2 12v rails)

No, it'd be labled 12v1, 12v2, 12v3, etc.., the -12v is something else, your going to have to buy a new PSU the one you have now isn't going to be able to run any decent GPU.

To find the actual watts you use a formula. If it's a single railed unit you take the amps on the +12v rail and multiply by 12. If there's multiple rails it gets trickier but as long as you buy a good quality PSU it'll usually do the math for you and tell you right on that same sticker.
