Power Supply Question

Can somebody please explain to me what this means, "300 watt or greater power supply with a minimum of 20 amps on the +12 volt rail." I understand the 300 watt PSU, but I don't understand the rest. Thanks!

amps are a measure of current. A power supply uses different "rails" which deliver power at different voltages. Your CPU+GPU will use 12v power when they are running, and either 5v or 3.3v (not sure which) when they are in sleep mode. The rating of rails in amps describes how much current can be pushed through the rail at a rated voltage.
