Where can I get news about power supplies? How do I know which power supply to buy? Motherboard — Be sure you know what kind of motherboard Desktop, Server, Laptop, etc. This is a critical component of your calculations because almost everything within your build plugs into and derives power from the motherboard. So make sure your PSU has enough cable to support that. Most PSUs will have at least one cable that is compatible with either an 8-pin or a 6-pin connector.
Memory RAM — Always know the number of memory sticks that your motherboard can support as well as the size GB of each one. Optical Drive — If your PC build includes an optical drive, be sure to include this in your calculations. Solid State Drive SSD — You need to know the size GB of each solid state drive that you currently have within your build or that you would like to include. Remember that sometimes these can be attached to the motherboard.
You can calculate Watts using the relationship between Amps, Volts and Watts. Find out how to convert Watts to Amps here or how to calculate Ohm's Law here. Amps measure the flow of electricity as an electric current.
You should think of electric current as the flow of water through a hosepipe. The more water flowing through the hosepipe, the stronger the current is. Volts are the measurement used to determine how much force is needed to cause the electric current to flow. In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow.
Hello Sandra, do both run on V? If they run on V, the amps are halved. Additionally, the fridge might draw Most fridges run on much a lower percentage and hence draw much fewer amps.
I have an inverter AC watts, v. With the equation you provided, it consumes 7. Is this a feasible setup? Am I correct in saying I can run the AC even 24hrs? Hello Franz, two Ah batteries have a Ah capacity. However, the batteries run on 24V while AC runs on V. At V, it does consume 7. We live in our 5th wheel. Generators run out of gas.
I was thinking about deep cycle rv batteries and solar panels to charge the batteries during the day. There are many 12v deep cycle batteries that put out AH for their 20 hour capacity. Can 12V batteries provide that amount of power? I am considering hard wiring with switch boxes a amp welding mach.
Hello Roy, it depends on the voltage. You would need a much stronger generator for amps. Hello, I have a wall baseboards heaters in my basement for a total of Watts. My breaker is 25 Amps.
Can I add another Watts? Hello Serge, the voltage is V? Additional W would add the total to W and My understanding is that I would need to run amp circuits to carry this load is that correct? Also, can you calculate the cost of electricity used in a 24hr time period. Hello Max, nice rig. You have Your understanding is correct; you will need 3 20 amp circuits. You can use our power consumption calculator here for all these calculations.
Each hour, you consume Hope you can help me understand it. And now I have a device which needs W DC power. An AC-DC power adapter has been provided and it has the following. The true measure of capacity is Wh or Watt-hours. You can use this Ah to Wh calculator to figure out how many Wh you have. Alright, so you have a 16,Wh battery.
Want to hook it up to V to run an AC?
