APC config modes

[Gaurav]

when i run the apc UPS medium sensitivity setting(factory default), the UPS seldoms run on its backup and after 10 to 15 mins i had to switch off my PC, which i did'nt want to.
My question is that if i run the UPS at low sensitivity setting will it be safe for my computer and various other components.
using the following config
c2d E6300
kingston 512MB ram 667MHz
200gb seagate hdd
1dvd rom, 1 dvd-rw drive
peace cabinet (zebronics) with three fans.

I run it high settings and it gives me backup of arround 35 minutes with all graphics cards etc.

I think setting at low won't be safe. It has been mentioned there next to the settings in parachute software.

I am talking about 800 VA. Can you check how much is the connected load on your UPS. At full load the backup will only be 5-7 min. which ever UPS may be.

For example, My APC 800 VA is capable of supplying 540 watt, where as all my componenets presently accounts for 156 watt only, so i get more than half an hour backup [no CRTs]. If I load this UPS to say 540 watt all together, then it will give me only 5 minutes.

There are two fuctions of UPS to protect PC & to give backup. The protection is most important to indivisuals, where as backup may be relevant to coporated like banks etc. For indivisual home user a backup of 5-10 minutes is ok.
