It should say on the label, but if not, you can multiply volts times amps to get the wattage.The power supply for these puts out 2 voltages (12V and 5V), so use 12 V to get a more accurate figure.See if your label has volts and amps listed, then multiply these to get wattage. Watt=Volt X Amp.

All the information you need is in your text :>)

Volts, Amp Watts To determine the wattage, use a simple multiplication formula. The ampere (or**amps**) is the amount of electricity used. Voltage measures the force or pressure of the electricity. The number of **watts** is equal to **amps** multiplied by **volts**.

Power Supply - 200 Watts

That is the supposed Maximum Wattage the computer will use per hour.

Variables come in to play, however;

1) Back when the computer was made, the Power Supply manufacturers were 'fudging' the real maximum rated Wattage.

True ratings were more like 60 to 70 percent, of what was actually stated.

Divide 200 by ten; take it times;

6 for 60 percent. 120 Watts

7 for 70 percent. 140 Watts

So, the Actual Maximum Rate Wattage, could be as little as 120 Watts, or a little more than a 100 Watt light bulb.

2) Second variable is what is the computer being used for?

Surfing the internet? About 100 Watts.

Playing an intensive game, (Yeah right. Not on that computer), or using an intensive program?

Then, you may be using the Maximum rated Wattage,

120 to 140 Watts.

So,........the hourly wattage rating, could be as low as 100 Watts per hour, or perhaps up to 120 to 140 watts per hour.

Also include the power used by the monitor.

If you do not have the specifications of the monitor, see if you can look them up online.

My HP 2009M uses 47 Watts, (2 Watts when in Sleep Mode),

My other monitor I use (Dual monitors), is an RCA 26 inch HDTV,

(RCA L26HD31)

Uses 82 Watts,

(And the power supply for my computer is 500 Watts.

Hmmm,............no wonder the little wheel spins so fast in my electric meter! lol!)

Add the two together to get a basic conclusion, of what Wattage per Hour your computer system is using.

Don't forget to include printer/scanner/fax machine/copier, WHEN being used.

For additional questions please post in a Comment.

Maybe a dumb question, but what do you need a transformer for a washing machine? Washers typically plug into a standard 120 volt 15 amp outlet. To figure out the wattage, use the simple formula, P=E x I. There will be a tag somewhere on the machine stating current draw, which is "I", "E" is your voltage, and "P" is your wattage which is what you'll figure out after reading the label on the machine.

Hello,

The calulation of max wattage is going to be 750 watts at start up and be around 500 on normal running wattage after start up so a 1100 watt generator should be fine.

Hello yes you can the Important thing to remember here is not to exceed the wattage that the transformer puts out.

Add up the wattage of each bulb that you are running and ensure that you do not exceed 300 watts.

for example a 300 watt transformer could drive

a. 10 - 30 watt bulbs

b. 20 - 15 watt bulbs

c 75 - 4 watt bulbs

Its also ok to mix bulb wattage for example I use 10 watt bulbs in the fixtures in the front of the house but also power 4 20watt spotlights from the same transformer.

Hope that helps

Wattage used varies greatly by product. Obviously the higher the watts, the faster it should warm the vehicle up. If I had to put a heater on my TDI I'd look at the frostheater. This particular heater uses 1000 watts. Google it and check it out

the needed wattage is directly linked to the componets you want to use other then the mobo itself. the main power surges are the CPU (takes 40 to 110 Watts) a graphics card (from 5 to over 150 Watts) the Drives (about 25-30 Watts eachs), the RAM and all the other addons and gadgets you build into your PC. Just add the different Wattages together and give it quiet some headroom. I usually drive this kinds of mobos with 400-550 Watts PSU to be on the save side, if i use a more or less "standard" graphics card, and even more with high sophistcated cards or lots of drives or such.

if you "see" low power (Volts) it might also be a problem with a partwise defective PSU.

Hi and welcome to FixYa,

It would be safe to use an amplifier slightly lower than the maximum rating of the speaker. In this particular case, 350 watts or lower would be just about right for each. If you are wiring the 2 subs in parallel and powering them with a single channel amp, then a 700 watt bridged would also work.

Good luck and thank you for using FixYa.

maybe is 115 to 125 watts.but if want to see the true wattage of your unit ,look at back of your tv set then read the label the tv ,you'll find the true voltage and the wattage of your unit.

The output power for model MA-780 was 700 watts, so I'd bet yours is either 600 or 700 watts.
