Power Supply

Is it possible to run a computer of 550W power supply with a 1000VA inverter?

Recently I bought a 1000VA inverter for my home use. In my house there will 4 lights and 4 fans running with that inverter power supply. If I run a computer which have 550W power supply, will there be any possible of burning out of my inverter. The shop from where I bought the inverter, they told me that there will not be any problem. I am confused.

OK, let me simplify this for you. It will probably work, but you shouldn't do it.

Yeah, I know that sounds like a contradiction, but it's not. I used inverters for years. The HIGH-QUALITY ones will last several months, maybe a year or longer...
But only if they are loaded below 50% on a regular basis.

If you load an inverter much past 50%, they will die quick. Like weeks or even days. I'm talking about good quality inverters, not the cheapies.

Your 550W power supply is probably drawing about 300W maximum *from the inverter*. That's based on the fact that most computer systems max out around 200W or less...but there is some energy wasted as heat, also. So round it up to 300W from the wall outlet (or inverter in this case) and that's a pretty good estimate of what the inverter is actually supplying for the computer.
It would be kind of silly to run a computer power supply off an inverter and run a monitor off of the wall outlet. So, add in another 100W for the monitor.

Now your 1000VA inverter is loaded to 40% and you haven't turned on any lights or fans.

Turn on lights and fans? Now you'll be somewhere above 50% loaded. In my experience, inverters die QUICK if you load them like that.

I predict it will indeed work, for a short while.

You should up to 2000VA or even 2500VA, if you want a more reliable solution. But don't buy cheap.
