Guys really need your help, the problem is very-very irritating.

The problem is-my PC restarts with power goes :@....i have Microtek 1000VA ups, It doesn't restarts while idle load or like movies watching or net surfing :no: , it only restarts while playing games or while any 3dmark running ,means on max load it restarts, can anyone exactly tell that what's the reason. :(

Here is my rig

Phenom 2 955 @ 3.2ghz

MSI 790gx -g65

4 gb ddr3

4X500GB segate

GTX 275

Real power 750 watt.

Help guys this is really irritating :@

All of a sudden everything restarts when power goes :(

i know many ppl here have much more high end rig than mine, then what UPS you all use with it...

Please replay..
 
1000VA does not equal to 1000watts. Your UPS probably delivers only about 600 watts.

Typically, a UPS has a VA rating. The VA rating is the maximum number of Volts * Amps it can deliver. The VA rating is not the same as the power drain (in Watts) of the equipment. Computers are notoriously non-resistive. A typical PF (power factor: Watts / VA) for workstations may be as low as 0.6, which means that if you record a drain of 100 Watts, you need a UPS with a VA rating of 167. Some literature suggests that 0.7 may be a good conversion factor, but this will depend heavily on the machine. WARNING: Don't take my word for it! Note: Some UPS's can continue to deliver power if the VA rating is exceeded, they merely can't provide above their VA rating if the power goes. Some can't provide power above their VA rating at all. Some may do something really nasty if you try. In any case, I strongly recommend not doing this under any circumstances.

^^ thanks for the post.....but i asked the microtek engineer he said 1000VA means equals to 700Watt so i guess watts is not the issue because this 750watt PSU don't give total 750watt and AFAIK my rig not require more than 550watt(just the CPU no monitor nothing , this issue i think of some sine wave.
 
if your current UPS worked fine under same conditions before ,then its clear that it the UPS.The problem occurs when the mains power goes off , the UPS not able to change over from the mains to invertor mode (battery), its a small factor of a sec, but this carry over procedure fails (on hold on UPS), and this small milli sec gap( no power stage for SMPS) causes the PC to restart.In Many cases these problems are also causes PC parts to get damaged eg:HDDs .or even OS crashes & BSOD.

So recheck the same with your UPS ,if its UPS problem call the Microtek service people for repair.THe best solution is (technically) online UPS, where the above matter is not a question (if the UPS is under desired load).

No i have this issue from the day i bought it.

From your post it seems like the sine wave is the issue, but the current UPS i have is meant for PC work only na. so why these kind of irritating issue.
 
sir, Its not the sinewave issue, its a problem found on many models of UPS. The best solution is get a decent 1000VA UPS from good brands like PCM,Numeric,APC,Trip lite,Delta etc.I can promise that your problem gets fixed. Also if your friends are having any these UPS, you can check the same.Also if you have any technicians having energy watt meters with them , you can check exactly the watt/load usage under heavy PC load,and to conclude the current UPS load status.

The current problem is based only on swiching time problem of UPS on some above threshold loads !commonly found on many UPS. Also i can promise that your current UPS will not have any power blackout issues with the standard PC config ! is it ture ?

Ya very true..a standard PC config don't have this issue. then suggest a specific model of APC UPS. I don't have any friend who have these UPS suggested by you,( they don't such high end rig), and if you promise that my issue will fix changing the UPS by a higher brand and powerful , so i prefer APC brand, please Post link of some good model of APC ups, i only need 10-15 min backup so that i can save the game and shutdown the PC properly.

Ya Numeric brand will also do, i have a good dealer of Numeric.

@TE Guys replay....suggest some models, its really urgent, i can't play games in day time as the power cut has increase, only can play games in midnight from 12:00 to 3:00 because of less power cut.
 
go to the apc website and use the ups selector to find the best ups for your comp.

UPS Selector Sizing Applications

As a forethought, always keep room for upgrades when using the selector. ex: if you have 1 hdd, select 2 or 3 in the selector so that your ups will still give sufficient backup time.

remember more backup time you select, more expensive the ups will become. backup time of 25-30 mins is sufficient for most people, for saving apps, finishing a dvd burning session, or closing the comp safely.

I found three UPS with the help of UPS Selector Sizing Applications but it only allow max 4 HDD i already have 4HDD and will add more 2-3HDD, also their is no option of additional VGA card,

But after filling the require blanks i found three UPS

1.APC Smart-UPS 1000VA USB & Serial 230V

2.APC Smart-UPS 1500VA USB & Serial 230V

3.APC Smart-UPS 2200VA USB & Serial 230V

This UPS Selector Sizing Applications is good but can't add as much hardware as we want.

so @TE guys i want you personal views and ideas on UPS, there are so many ppl here having high end rig....what UPS you all use to run your monsters????

tell me your personal experience which UPS you all are using.....

waiting for your replay.........

This is really very F**king irritating issue....Its gonna be one week i haven't played any game properly:@ its really very risky for hardwares...while gaming so many things are on almost max stress and usages and all of a sudden everything goes off, so irritating , i am really afraid for my hardware :(

will never buy or suggest anyone these normal microtek UPS (for high end rig) which i have currently..nope never
 

How much vCore you using for that..?

It probably that on 'load' the UPS cannot supply enough juice. So you would be crossing the 600-650W range, which is the maximum that UPS would be capable. Probably lower.

Thanks for replaying .

Ya my vCore is 1.387 V around at full 4core usages. Never do OCing (vCore means cpu voltage- correct me if i am wrong)

I noticed one more thing i.e on just cpu test like OCCT my UPS doesn't restarts but when both cpu and gpu are at stress like gaming or 3dmark it restarts.

asingh your statement is also true i.e when idle my UPS doesn't restart because their is not much load, but while max load it crosses 600-650W range which is close to my current UPS max output so it restarts. so it means clicking of power to battery is not the issue here? (coreect me if wrong) the wattage is the issue..
 
I just plugged your values into the online Thermaltake calculator, and on full load it is ~567W with the OC+vCore you mentioned. So it quite obvious the current UPS is not upto the mark. A 1KVA UPS (good brand), should be fine for you.

Ok now its sure na that wattage is the issue?

Then suggest a very good and reliable UPS, i need just 10-15min backup, suggest for future proof also as these things are changes within a year.

Like in future i will use 1000Watt PSU of Cooler master, which will give max out put till 960W around, for SLI my cards or 1KVA will also not work.

Suggest a UPS that can handle 1000W total with monitor+CPU, a solid UPS with no issues like this microtek , budget is 10k , but please please ensure me that it won't give these kind of irritating issue.
 
^^

It handles mine fine. Never faced an issue. What are the prices of the above 2 units. You sure, you will touch 1000W load..?

Ya i am 90% sure i will touch not 1000W but around 890-920W with CM 1000W PSU(good series like new silent pro gold series) in future not more than 1000W PSU. the reason i am forcing on 1000W is because this current microtek UPS has made me very very disappointed, its one week i haven't played proper gaming, what proper not even a single stage in a game, if their is a voltage fluctuation in the house then also my PC restarts :@:@ so irritating. so need a best and solid UPS this time, backup time is not an issue but load handling is very important.

And i search on google and found that Smart UPS are much better than back up UPS.
So @TE any one here knows what will be the prices of 1500VA smart UPS or backup UPS

here on primeabgb i found the product but not the price APC Smart-UPS 1500VA USB 980*Watts/1500 VA

--- Updated Post - Automerged ---

Guys found on lynx india, but is these price updated? APC Back-UPS RS 1500VA, 230V is for 14k

APC Smart UPS 1500VA - SUA1500I
 
If Voltage fluctuation is the issue adding a servo stabilizer to the current setup will fix the issue. But go for Online UPS if price is not a problem (Numeric Online UPS 1KVA 36V ~ 12k w/o batteries). Online Ups will give continuous pure sinewave output at any instant.
