the power supply is tracked by two's.

A dual power supply refers to a system that provides two separate power sources to a device or circuit. This setup offers redundancy and can help improve reliability in case one power source fails. It is commonly used in critical systems where uninterrupted power supply is necessary.
AT Power Supply - still in use in older PCs.ATX Power Supply - commonly in use today.ATX-2 Power Supply - recently new standard.
power supply is a device that supplies electric power to electrical load

We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
AC is supplied to the input of DC power supply. One way to get to DC is to full wave rectify the AC sine wave. Basically you flip the negative side of the AC waveform to the positive side. You are left will all positive voltages varying from the peak voltage to zero and then back to peak. To make DC you need to smooth out the valleys and make them as close to the peak voltage as possible. You do this with various types of filters that usually involve a large capacitor. Once filtered you can use various circuits to either create a fixed DC output voltage or a variable output.
Use a power supply tester. You can get them on ebay for under $5.
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
if you are reffering to Vcc than it means- It is the positive power supply used for TTL gates it is nothing but simple dc power supply. if we use CMOS than we use Vdd for indicating power supply these are method for indicating power supply.
Pentium MMX and AMD K6 both use dual voltage. The lower supply voltage is used for the core and the higher voltage is used to power the I/O pins.
