suggest a cheap UPS

[soumyaxyz]

I have power backup (inverter) in my house but it takes around a second or two to take over. i need a ups for this interval. The PC is has 520W Psu.

I have a ancient proview ups (that no longer works but i can probably get it working by replacing the battery)
it has a 220-230 Vac 56/60 Hz input-output rating

so will fixing it work or do i need a new one
if i need to buy a new ups please suggest the cheapest possible sollution

what is your pc configuration. give exact model number. saying i have 520W psu is not just right.
mention your budget too.anyway the minimum you should go with is the apc 600va at 2.3k.

specs is in my signature . its seasonic s1211 520 W

i was wondering since i need backup for only a sec or two
if the old one with a replaced battery could work

getting a good quality ups is important.the old one may not suffice. you might require apc 1100va as you have a beasty gpu.

The inverter if was a 600/800 va then how would it handle the load,

Computers must be run on pure sinewave
The op's inverter might be an ancient square wave so it is taking time during changeover from Mains to battery

If it is new he could simply change a switch in the inverter as ups mode and no more ups
