Answer +5, -5, +12, -12
Two technicians are discussing how to measure the voltage outputs of a power supply. Technician A says that the power supply must be connected to the system and turned on before voltage can be measu?
It does have to be turned on. A highly regulated PS will be the same under load as without a load. But it may not be able to supply the amps. Best connect it and t…est it. WHO WON?
+5V, -5 V, +12 V, and -12V Source: http://www.studydroid.com/index.php?page=viewPack&packId=85684
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the… logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
Generally, there will be a 12+ volt rail, a 5+ volt rail and often a 3+ volt rail.
by d way input only
Depends on the power supply, usually theres a red switch on the back that says the voltages that I can be. You can also change them by going to the boot setting(setting when t…he computer boots up)
-12, +12, -5, +5 & ground.
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
Input would be 120v at 60hz. Standard US wall power.
Output is: DC10V - 800mA - Center Positive
the ATX standard supplies three positive rails: +3.3 V, +5 V, and +12 V
The electric voltage are energy to my system.
This can very greatly from computer to computer. You will have to open the case of your computer to tell.
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and… packaging will state voltage recommended for the product.
