No amps do not have to match but the power supply or charger must be able to supply enough amps as required by the device being powered or charged. LM358 can be used for the opamp as long as you take into consideration maximum operating voltage.

PC power-supply cables use standardized keyed connectors that make it difficult to connect the wrong ones.
Amps computer power supply. Your CPUs power is usually derived from the 12V power supply in your computer which is stepped down to achieve the lower CPU voltage. The circuitry that isnt highlighted represents the existing circuitry. I just need to figure out this part so I know what resistors I need to get and calculate the wattage.
This laptop was produced in 2004. I am trying to use a computer power supply to run a vape mod that is designed to run at 84 volts and 30 amps. The original power supply put out 20 volts at 35 amps.
The case fan shown below is rated at 12 amps and 12 volts or 144 watts. Certain PC like LCD or LED monitor use more than 5 amps because of the display. I wonder does their amps on the supply have to match the amps for the laptop or can it exceed the requirement.
Now for the connections. Computer power supplies are available in a wide range of power output options with 1500-200 watts being very common but others as large as 700W or more can be found although they cost a bit more. Output specifies the characteristics of the power provided by the power supply to your computer.
It is a de-facto standard in the industry that the watt rating is approximately 60 of the. Power Supply Ratings amps Power supplies vary in ratings by manufacturer and date of manufacture -- consequently the power supply you have on hand may not exactly match the output ratings listed below. The input numbers are all about connecting to the wall socket.
So the amps a computer use should be 25 if the power supply comes rated at 300 Watts. There are actually a few different ATX power supplies all of them are designed to provide 33 5 and 12 volt outputs. Larger computer equipment made prior to 1996 also typically used this type of power supply and exhibited a power factor less than one.
In reality that current is a little higher because the power conversion circuitry isnt 100 efficient and some power is lost by default. A power supply rated at 200 watts will be similar but probably have slightly different amperage figures. 300 watts line voltage 120 volts 25 amps.
The current output will limit how much power you can get from a car amp. This is is often something like DC 195V 462A meaning that this power supply provides electricity at 195 volts and is capable of providing a little over 45 amps of electricity. Also how many amps is a PC power supply.
UPS have both maximum watt ratings and maximum VA ratings. Adaptation computer power supply for car amplifier About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy Safety How YouTube works Test new features 2021. The current draw for the same power will be about 55 amps.
The main power connector supplies power to the motherboard of the computer. Theres a way to understand if your PSU relies on higher or lower energy consumption. ATX Power supplies have standard sizes and connectors for use with ATX motherboards.
It does require adding hardware to the existing power supply but it doesnt require adding another supply or building a new supply from scratch. 12 amps on the 5 volt bar represents a load of only 6 watts and apparently 6 watts is all you need to tell the PSU shutdown circuit a load is connected and there is no need to shut down the PSU. 24 Volt 5 Amp Power Supply 220 Ac To 12 Dc Converter 120w Power Supply Supplier S-60 Power Supply 5v 5v 12 Amp Power Supply 798 Response Rate Contact Supplier.
Look at this calculation. Usually a typical computer uses an average of about 65 to 250 watts of also between 3 to 5 amps. So your original power supply could produce up to 70 watts of power.
20 x 35 70 Watts. In practical terms that means the amperage rating of a power supply or charger must match or. Herein how many amps does a typical desktop computer use.
Representative ATX 12 V. Neither the watt nor the VA rating of a UPS may be exceeded. ATX is an industry specification that means the power supply has the physical characteristics to fit a standard ATX case and the electrical characteristics to work with an ATX motherboard.
The power lights so not turn even though it is receiving power form the supply.
