I am planning to upgrade to a HD7750 card. i am currently on a crappy PSU. so i will be upgrading to a Corsair 430cxv2.
the main problem lies with my UPS. i bought around a month back. its a BR600CI.. its 360 Watts / 600 VA. there is absolutely no question of replacing it so soon.

now the question: both my CPU and Monitor (80W) will be driven by the UPS. will the current UPS be able serve its purpose if there is a power cut, i.e., will it give me some back up, say 2-3 mins(just the time to save my game/work and shut down immediately), incase the power goes off? if yes, what will the approx time?? [please note that the total wattage needed will be around 510W, whereas the UPS itself is 360W/600VA.]

if no.. well then. goodbye upgrade.

Well, AFAIK CX430 is Active PFC PSU, and the UPS is "Waveform Type - Stepped approximation to a sinewave", a modified sine wave.
So it is more likely to not work, as Active PFC Psu dont particularly like cheaper UPS ;)

Mine didn't work, and I learnt the hard way..... and now my whole PC is on direct power line.........until I can afford one of those true sine wave UPS (above 5k) :(

just check the battery is good, assuming u dong have crt and an uber overclocked proccy, u should get ~10 minutes backup/more with a 7AH standard ups battery.

I think the UPS and PSu combo will work just fine ..

- the battery is fine. its 1month old. i have an LG studioworks CRT. the proc is NOT OCed.

:nervous: its just that i'll be making a biggish investment here and i want to absolutely sure before hand. i am pretty sure the sales people at the shops know shi*'sworth, so asking them would be a farce. i am asking coz you guys have lots of experience in these matters. i'll hang around the forum for few more days, poking around and disturbing people till i can reach a satisfactory result. :p :)

Re: UPS suggestion for GFX & PSU upgrade

Oh well, everytime power went out, the system turned off directly w/o going into backup mode while connected to UPS
It worked fine with my "INTEX" el cheapo PSU but not with the CX430.................

If you are lucky, it will work..................

Re: UPS suggestion for GFX & PSU upgrade

i will be using the 430cxV2... ??

btw.. i saw somewhere that the corsair 450 costs less than the 430cxv2. why is this so??

it's better to stick with cx430v2 though it costs a few bucks extra compared to vs450 which don't has any proper reviews.

as expected ;-) anyway, glad to know and thanks for the feedback - some people just creates thread and when they solve their issue feels no urge to provide the final result/feedback.

@ debarshi - can't say bro - I really don't have much knowledge on PSU/UPSwaveform Type - read something like those some years back with not much attention and when I used a corsair PSu with APC 700VA UPS the combo just worked and so far personally I've seen every APC UPS working good with corsair/cm psus.
