The input power of a computer Power Supply is usually 110-240VAC. The power supply usually transforms the input voltage into 3.3V, 5V, and 12V...all in DC. Different components require different voltage...either (1)ONE of a combination of these. 12V is one output voltage of the PSU(Power Supply)
What else can I help you with?
Can you charge a 12v lawnmower battery with a 12v car battery?
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
Can you use a 14.5 DC power cord on a 12V computer monitor?
No. If the transformer outputs 14.5V it is very unwise to hook it up to a 12V Monitor. The transformer needs to be able to output 12v, the polarity needs to be correct (e.g. tip + tip -), and it must be rated to provide at LEAST the required amount of amperage.
Convert 12v to 3v DC?
if you have 12v dc then you can use a 4 ohm resistor
What voltage does a PCI slot use?
-12v+12v+5v+3.3v
Can you use a 12V 7AH charger to charge a 12V 120AH battery?
Yes it will work quite well.
Can you plug in pest control into a 12V battery?
In order to use the "plug in" pest control with a 12V battery, the device would have to have power requirements less than or equal to that which a 12V battery can provide. The pest control would also need an adapter to use the 12V battery.
Can you use a 12v 7.2 ah battery to replace a 12v 4 ah battery in an alarm system?
Yes
Can a 12v plug be used in the 1999 Subaru Cigarette Lighter socket Manual says only to use a Subaru made plug?
Use your 12V plug.
Can a computer case fan run off of a cars 12v dc line?
Yes, no problem.
Can you use and charge and battery at the same time?
I kinda wonder that myself...I am running my 12v LED computer fan from a 12v battery pack from my Ryobi drill with the charging cable inserted into the battery...it says its charging, and my fan is running...So, I will see if it doesnt explode...fingers crossed...
What if you use a 12V 1.5mA power adapter in place of 12V 1.2 mA one?
It will take longer to charge the device
How many amps in 12v 150w?
Volts * Amps = Watts 12V * A = 150W A = 150W/12V A = 12.5
