CPU [i7 3770k+Z77xup5th+7970]
Monitor : ASUS 23" IPS LED 3D
Speaker: Altec Lansing 2.1

1.Which Brand?
2.How Much Power ?............. 600mva / 800 mva / 1Kva??
3. Is Service Center is available for your suggested Brand in Kolkata?

I am aiming minimum Electricity Cost , and just enough to close every application in case of any power failure ........... normally without any corruption

 

[Myth]

1. APC
2. Backup time depends on the current load of the total system. Take a 1/1.1kva to be safe.
3. apc service is present on kolkata.

1. APC
2. since you want it just for power failure, get 1.1KVA, did fine with my 2600k+GTX580 setup.
3. Yes, there is a dedicated service center+rashi as well, also 2 yrs complete on site warranty.
