Which switch supply power to a computer?
Power switch on the back of the computer, usually just on a desktop. Power switch on the power strip, surge protector, or UPS, if you're using any of them. Check for disconnected computer power cable connections. A loose or unplugged power cable is one of the top reasons why a computer won't turn on.
What voltages are supplies by the power supply on your system?
The power supply is visible from the back of many systems because it contains the power-cord receptacle and the cooling fan. Power supplies, often referred to as "switching power supplies", use switcher technology to convert the AC input to lower DC voltages. The typical voltages supplied are: 3.3 volts.
What is DC voltages does a PC power supply provide?
Power supply is a reference to the source of electrical power. Most electronic circuits require a DC power supply. Chances are you have one at home already, and can use it for physical computing projects. The most common operating voltages for microcontrollers and digital processors are 5V and 3.3V.

A decent model that sports a 27-inch display and comes with a 2.66GHz Quad-core Intel i5 processor and ATI Radeon 4850 graphics consumes 1.21 amps an hour when idle and 3.04 amps/hour while running at its peak.
How many amps does a computer use?
The amps that computers draw fall anywhere between 0.25 and 2 or more. A desktop PC uses up to 1.67 amps per hour with the printer and speakers running. So, a computer that runs as long as eight hours a day needs up to 5 amps.
How much power does a computer monitor use?
Computer monitors are crucial to energy consumption. Desktop monitors that we usually see need 0.15 amp to 0.5 amp tops. The calculation for CRT monitors or LED-backlit screens will be a little different from ordinary monitors or computer screens. For example, a 22-inch LED-backlit LCD monitor consumes up to 0.30 amp for five hours.
How many amps does a loudspeaker need?
The loudspeakers need 0.17 amp per hour. There’re significant deviations from the above estimates when it comes to workstation computers which usually consume 2 amps to 3.50 amps per hour when performing at 100% and 0.75 amp to 1.20 amp per hour when at rest.
What is the deciding matter of a PC?
The configurations of a PC and the way one uses the device are the deciding matters. Let’s get a hold of these and then move forward with the actual amps that a computer pulls.
What does less consumption mean?
Less consumption means lower utility bills which ultimately lead to more saving . You can’t really begin an energy efficiency initiative without knowing the amount a computer requires for its regular operations? So, how many amps does a computer use?
How much current does a power supply need to run all 3 fans?
So in this case, you're running all three widgets on a 1 foot gear, only you have to crank that gear three times as hard so all three widgets can run. That is analogous to amperage. So the power supply needs to stay as 12 volts only it has to provide three times as much current to run all three fans and computer power supplies typically have plenty of amperage to run especially fans.
What will happen if one fan is running too fast?
What will actually happen is whichever fan has least drag and or best torque will run really fast and the others will stall or run much slower. You will be over-driving that one motor and will likely damage it. You can use a zener arrangement as suggested by wiebel, however those zeners need to be able to carry the full start-up current and may get very hot if one fan is struggling under a heavy load.
Can you run 3 widgets on 1 foot gear?
So in this case, you're running all three widgets on a 1 foot gear, only you have to crank that gear three times as hard so all three widgets can run. That is analogous to amperage.
Can you run a fan in parallel?
It is much simpler, and safer, to run the motors in parallel using a 12V supply that can deliver three times one fan's start-up current requirement.
Is it bad to run DC motors in series?
HOWEVER: Running DC motors in series is a bad idea. What will actually happen is whichever fan has least drag and or best torque will run really fast and the others will stall or run much slower. You will be over-driving that one motor and will likely damage it.
Step 2: Using the Case Fan: the Original Connector Can Be Used With Slight Modification
The connector that exits the power supply has a male connector with female pin sockets. When the key (rounded edges) are facing up the red +5 volt lead is on the right and the yellow +12 volt lead is on the left. The connector you want to modify is the female connector with the male pins, coming from the fan.
Step 3: Using the Resistor: Find the Two Output Connectors Marked P8 and P9
Both the P8 and P9 connector have ground connections but the ground connection on the P8 connector is what to use since most 10 ohm, 10 watt resistors have axial leads rather than radial although these are made too. The axial leads are not quit long enough to use the P9 connector by itself.
How many amps can a 400 watt power supply deliver?
My 400 Watt power supply can deliver 23 Amps through the 12V rail, and 40 Amps through the 5V. That's very good for something that, aside from the initial cost of the PSU, cost about $10.
What colors are needed for a power supply?
The only colors we care about are Black, Red, Orange, Yellow and Green. Any other colors are superfluous and you can cut them at the circuit board. The green wire is what tells the power supply to turn on from stand-by mode, we want to just solder it to a ground (black) wire.
Can capacitors cause burns?
While I'm reasonably sure that there isn't enough residual energy to stop your heart, those capacitors can still bite, and that can cause significant pain and maybe even burns. So be paranoid when getting close to the internal circuitry. It would probably be a good idea to put on some insulating gloves.
How much power does a USB port need?
The original USB standard required that a host be capable of supplying 500mA per port on request, though that is only after a negotiation happens between the host and device, and the host may decline. The device is not permitted to draw more than 100mA until it has negotiated for more. Thus the minimum you can count on without some intelligence in the device is 5v@100mA.
What is the difference between USB3 and USB2?
A standard USB2 port that provides the traditional 500mA of power will usually be black. A non-standard USB2 port that provides High Power for fast-charging devices is usually red. A USB3 port is usually blue. Note that USB 3 is still backward compatible with USB 2.0 and USB 1.1, although about th. Continue Reading.
What color is USB 1.1?
Although it is not specified, USB 1.1 and USB2.0 have been whatever color the manufacturer chooses (usually black or white), although there appears to be an emerging elective color standard that distinguishes USB2 from USB3. A standard USB2 port that provides the traditional 500mA of power will usually be black.
How many watts does a USB port draw?
The original USB 1.0 spec (and the updated 1.1) allowed devices to draw up to 500mA from the port. USB operates at 5V, so that means a maximum of 2.5 watts.
How much power does a micro USB port carry?
Also note that the Micro USB connector is only rated to carry 2.1A (10.5W), so that’s the maximum charge rate for a phone that uses 5V charging. It depends on what kind of USB port it is. The original USB 1.0 spec (and the updated 1.1) allowed devices to draw up to 500mA from the port.
