Huh? Did I miss something? We're talking about a power supply here, right?


A power supply should provide the specified voltage. The power supply must be rated at *at least* the current (Amps) or power (Watts) drawn by the load, but an excess here does not hurt. Some power supplies require a minimum load in order to operate correctly, that is not likely to be an issue here. You will fry a power supply if you pull too much current from it. You cannot *provide* too much current to the load -- it draws what it wants to. You *can* provide too much voltage.

Wrong... I'll give you an example which ANYONE and EVERYONE working with electricity should know, and if they don't they SHOULD NOT work on anything even remotely related to electricity until they do know it.

You know that it's the current of the electricity is what will kill you right? You could have thousands of volts running through your body and still live. How is this possible, you might ask? Well if the the current (power) is below .5 mA then it should not cause a problem. Ask any electricity teacher "At what point will electricity kill a human being?" and their response will be something along the lines of "Anything at or above .5 mA will (more than likely) kill a human being." Of course there have been cases that said otherwise but this is the majority case. Same thing applies to delicate electronics... apply more amps then it's rated to handle and it's fried. Just last week I fried a 2.4GHz wireless phone by applying a power supply that had exactly the rated voltge but was 1A instead of the required 800mA. I smelled smoke not long after plugging it in. All this in a unit that worked properly with the right PSU just 2 weeks before... the original PSU being lost. Need I say any
 more? Current is everything... voltage is nothing.

BTW- goto the nearest high school and ask the electricity teacher about this... see what he say... then compare it to what I said. Remarkably like, eh? LOL
