My PC configuration is this:

Pentium D 820
Intel 945 mobo
1 sata HD
2 cd drives
7300gs Gfx card
2x512 MB DDR2 Ram
15" monitor

For the present config a 500VA UPS is enough. But I will upgrade the monitor to 17" and probably the Gfx card too. Then will a 500va UPS support the new config? Or will I need 650VA?

I'm going for APC and the 650VA is costly. So I will buy it only if its absolutely necessary. Kindly advice.

People having similar config and preferably APC UPS, kindly respond.

APC is good and higher is allways better !! but That config will run with 500 VA i think as if i can run E6600 + P5N-E SLi + 3GB + 2 DVD Burners + 17" with my 4 year old Proview 500 VA, u can rest asure APC 500 VA is good enough for ur system !! though Cold start (Monitor or Full system) may be a problem !!!

I got 500VA APC and it is overloaded if i try a manual start(without AC)..go anytime for 650VA one.

^^ I'm having simiar thoughts after seeing this site

You can calculate your PSU requirement. Mine showed I need a 415W PSU excluding the monitor ofcourse. So a 500va UPS won't be enough.

I have mentioned that, with 500 VA, one will face problem with Cold Start-up !! but certainly running process wont be effected !! so, if one plans to for a Cold start, then even i guss 650 VA APC wont do, as if one need to work with Cold Start then some Double Battary 650 or 800 VA is needed...

so, as blackpearl said, his has a budget problem, therefore I suggested that 500VA

and rather than VA Backup will also depend on that Battary one is using !! :)

@blackpearl

As i have writen already that I am running 450Watts (ColorSit) with E6600 + 3GB + P5N-E SLi + now 3 HDD (SATA-II and PATA) and 17" Monitor, even with my 4 Year old Proview apart from Cold Start-up, there is not a problem with Power Cut (Yes my battary is pretty old therefor not more than 4/5 mins backup)

The 500VA APC is Rs 2400 and the 650 VA is Rs 3600.
Thats a big difference.

I don't plan to do cold start. I just want it to run for atleast 5 min so I can safely save my work, finish a half burned CD etc. Nothing else.

@Choto Cheeta :

I may have a 15" monitor right now but I would upgrade to a 17".
Also the gfx card might change. Then will a 500va be enough. Even you have a 600va.

P.S: I have a 500W smps. Consider that as a limit. But it won't stretch that far. :)

One question more: What is the wattage rating of a 17" CRT monitor?
15" ones are of around 75W.

I think the SMPS wattage should also be given consideration, especially with 500 - 600 W and above becoming popular.

APC u can Trust on that VA Thing :lol:

Quite honestly if u try mesureing that VA with Hardware !!! u will find, APC will b able to pass the test on delivering promissed VA rather than brand like Microtek or Proview or etc...

Its like that SMPS, u get a 400 Watts frontec or JBM type SMPS in just Rs. 250 or 300 MAX where as buy a Perx or such SMPS, same will Cost 3000 or more with those Brands :lol:
