PC Peripherals Need info about UPS

[mehrotra.akash]

I have the following equipment I need to connect to a UPS
1) 32inch Samsung LCD
2) i5-750 with 5770 Hawk and VX450w
3) 21 inch sony CRT
along with an inkjet printer, a scanner,router,cordless phone,mobile/laptop chargers,etc and settopbox

my current config is
LCD - without UPS
Computer - on a 600VA Microtek Heritage Plus
Misc stuff + CRT - on another 600 VA Microtek Maxpower with a failing battery

Also, I will not be coldstarting the PC or CRT on battery. The backup need is only about 5 minutes.
The reason I need to replace this setup as the Heritage plus is unable to provide backup to the comp under full load.
Can you suggest a replacement for these 2 UPS so that all the stuff can be connected to one UPS only, or if it is better then I stay with 2 separate UPS and replace the Hertiage plus with an 800VA one . I cannot go for APC UPS(line and neutral are reversed in my house and APC UPS refuses to work under such a conditon), and I believe Microtek is second best.
Putting the LCD on a UPS is not critical but would be preferred

get atleast a branded 1KVA (offline or online ) with external battery /built in. never buy local unpopular brands such as intex,fronttech,umax,energ,zebronics etc for a good spec,else R.I.P !!!!

didnt know those companies made UPS, all I had heard of were

APC

Microtek

Luminous

and maybe SuKam.

Anyways, are Microtek and Luminous OK?

and would 1KVA be enough? or would I have to keep one of my older UPS as well?
