I'm trying to power my pc off of 1 15 amp outlet that also has a tv (1amp), cable box (3amp), modem (1amp) and router (1amp) on it, but i'm not wanting to trip the breaker in the trailer i'm temporarily living in. This means i should be able to draw roughly 41 amps (12v*41a =~ 500). Power supply is a reference to a source of electrical power. Well, also the supply side is at a different voltage. So you can see that we two problems. The first is that we… Nov 12, 2004 13,837 4 0. Amperes measure power use, but watts are the more common designation for power consumption in electronics.

The capacity of the psu is quiet different than the 'current usage'.

These ratings can typically be found on the label on the back of the equipment. Since these power supplies were designed to work inside of a pc, you need to come up with an enclosure to mount them in. I'm trying to power my pc off of 1 15 amp outlet that also has a tv (1amp), cable box (3amp), modem (1amp) and router (1amp) on it, but i'm not wanting to trip the breaker in the trailer i'm temporarily living in. The main specification of a power supply is in watts. On the other hand, a desktop pc can use up to 1.67 amps per hour when its speakers or printers are running. If so how much room for upgrading will the power supply has as well would you say? The actual connections from the power supply are as follows: An atx psu has one 3.3 volt rail. Certain pc like lcd or led monitor use more than 5 amps because of the display. An advanced technology extended (atx) power supply is the most common kind, and it looks like a small box with multiple wires sticking out from it and a fan on the inside. 500 watts / (line voltage @ 120 volts) = 4.16 amps For starters, your car amplifier is meant to receive its voltage from a 12 volt dc source which is your car battery. Car amplifier and subwoofer powered by a computer power supply:

300 watts / (line voltage @ 120 volts) = 2.5 amps. The total power handling capacity of this connector is 58 watts. An advanced technology extended (atx) power supply is the most common kind, and it looks like a small box with multiple wires sticking out from it and a fan on the inside. Will that power supply in my first post link run this pc fine please? If you are using a power hungry cpu like a fx9590 that will be a problem also.

If you look at the power supply's label you will see that it can operate at as low as 100v ac which definitely will reach a little over 12 amps. So you can see that we two problems. On the other hand, a desktop pc can use up to 1.67 amps per hour when its speakers or printers are running. How a power supply works. Depending on the type of computer used, the amps drawn range from 0.25 to more than 2. The amps available is not the sum of the 12v1 and 12v2 numbers, but something less. Let's clear up any confusion about the term rail. There's a way to understand if your psu relies on higher or lower energy consumption.

For starters, your car amplifier is meant to receive its voltage from a 12 volt dc source which is your car battery.

When you convert a computer atx power supply into a dc bench supply it can include up to 5 voltage outputs plus a ground. When more amperage is required by the motherboard before the 24 pin connector was devised, this six pin inline connector was equipped with power supplies to provide supplemental power to the motherboard. Power supply is a reference to a source of electrical power. How a power supply works. This means i should be able to draw roughly 41 amps (12v*41a =~ 500). Common households use approximately 120 volts ac. This is the maximum power on average that this computer can consume. The best power supply for your pc build is the one that provides the right amount of wattage to all components simultaneously. Usually, a typical computer uses an average of about 65 to 250 watts of, also between 3 to 5 amps. The result is the total watts that your pc build requires. The total power handling capacity of this connector is 58 watts. Usually, a computer unit draws nearly 0.25 to 2 or more amps in a single run. I just need to figure out this part so i know what resistors i need to get and calculate the wattage.

It also has one 5 volt rail. The actual connections from the power supply are as follows: On the other hand, a desktop pc can use up to 1.67 amps per hour when its speakers or printers are running. Lets say i have a 500 watt, 12 volt dc power supply. Amperes measure power use, but watts are the more common designation for power consumption in electronics.

Converting atx power supplies from a pc. Load for mine is around 0.8 amps. It supplies power at 120 volts ac. Multiply amps by volts to determine voltamps (va). The main specification of a power supply is in watts.a watt is the product of the voltage in volts and the current in amperes or amps. How many amps does a computer require? For starters, your car amplifier is meant to receive its voltage from a 12 volt dc source which is your car battery. 300 watts / (line voltage @ 120 volts) = 2.5 amps.

I just need to figure out this part so i know what resistors i need to get and calculate the wattage.

By vented_swing_6295 june 7, 2018 in power supplies. This is the maximum power on average that this computer can consume. However, the computer will have a power supply rated at a set number of watts. Power supplies need a certain minimum load to work properly. For starters, your car amplifier is meant to receive its voltage from a 12 volt dc source which is your car battery. This is far more current than my mains power can provide. To convert watts to va, divide the watts by power factor. An atx psu has one 3.3 volt rail. 500 watts / (line voltage @ 120 volts) = 4.16 amps Watts (adapter rating)/voltage = amps so, the amps a computer use should be 2.5 if the power supply comes rated at 300 watts. An advanced technology extended (atx) power supply is the most common kind, and it looks like a small box with multiple wires sticking out from it and a fan on the inside. Certain pc like lcd or led monitor use more than 5 amps because of the display. These ratings can typically be found on the label on the back of the equipment.
