I've got an an issue with my UPS and today went to an technician to check to so he said there must be something wrong with the charger
anyway I have got Luminous Vista 650VA UPS. so it's definitely okay for me as I believe but I've got a doubt is this really enough for me?
I meant another unit but the same brand. I am wondering how long can I work with this UPS when it supplies the backup current.

Foxconn G41MX-K Motherboard
Hitachi 250GB 7200rpm Hard disk
Axle GTX 460(DDR 5,1GB,450W) Graphic Card
1 DVD Writer , Samsung.
Samsung 15 inches , Sync Master 632NW Model LCD Monitor
2.6GHz(Over Clocked to 2.8GHz~ Dynamic Overclocking) Intel Dual Core Processor.

I think My 750VA UPS lasts about 10 minutes... long enough to finish what I am doing and shut down. How long are you expecting your UPS to last?

I'm actually a fan of APC.

As for how many VA's to get keep in mind two things:

1) how long does your PC last if you UNPLUG it? (while hooked up to the UPS)

2) The UPS battery loses capacity over time. Don't cut it too close.

More VA?
- if a new UPS supplies power for less than 30 minutes (remember the battery loses capacity)
- if a two-year-old UPS supplies power for less than 10 minutes

Why UPS?
I like them to prevent damage caused by the PC shutting down unexpectedly. I don't need to pay for the VA to be so high that I have an hour of use.

It should be plenty as long as you plan to power down soon after a power loss.
