the power supply is tracked by two's.
By using a voltage divider, that is two resistors of the same value in series across the DC supply. Half of the supply voltage will be at the point where the two resistors is connected. But how much wattage of those resistors is also an issue.
If it as a 20 or 24 pin connector and a 4 pin connector then it is a ATX power supply.
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.
The rated powers, printed on each lamp, will no longer apply. You will need to measure the load current (I) drawn by the two lamps, together with the supply voltage (U), and multiply the two values together: Power = U I

The computer will only consume what power it needs. No diffference. if you have a 350watt power supply, and it is using more then 70% power consuption, the life of that power supply will be short, so always aim big when picking out a power supply, ie: 50-100 watts more than what you would actually need.
CPUs get power from two places-- From the motherboard through the tiny pins on the bottom of the CPU (Which in turn gets power from the 20 / 24 pin connector that connects tot he power supply) and from a 4 / 8 (Only on the newest boards) - pin connector that directly feeds the CPU a very steady supply of power. Both come from your actual Power Supply.
Power supplies can supply AC or DC current.
