Re: Computer and PSU
If you look on the label of your power supply, it will list out the voltages. 3.3V, 5V, 12V, and so on so forth. Now, to get Watts, you use the simple equation of Voltage * Amperage = Wattage. So...Lets say that his 5V rail has 20A, that means that he has 100W on the 5V rail. Since his computer is 5V based, it uses more 5V than 12V. So, if his computer only draws 10A off the 5V rail, he's fine regardless of the wattage rating of the power supply.
