UPS problem in low voltage, power fluctuation, PC getting restart..

[kool]

Hi guys.
My UPS is now 1 year old, its working fine until power fluctuation has started in this summer. My PC has restarted more than 5 times a day. UPS is giving backup, but unable to control power fluctuation in my home. These little bit low voltage, Others appliances working fine even in low voltage like refrigerator, LCD TV, Tube light 40w etc.

So, guys give me any solution for this problem.. for low voltage, power fluctuation. Is there any device that can control my UPS fluctuation? like stabilizer? what would be its cost?

I've INTEX GREENX 600VA

Well instead of buying stabilizer get APC 500va ups, should be around 2k.

PS: Intex psus are crap, had issues with one long back.

Electrician has suggested me to buy a voltage stabilizer of 500va. u guys tell me now, is 500VA good for me or not? reply...

I suggest you to get a proper UPS. An APC 500w or a Numeric of similar rating would be great

u guys tell me now, is 500VA good for me or not? reply...

What is you're complete config? If you have no GPU its fine

Also, what PSU do you have?

[kool]

now i don't want to buy any ups. Before this i had microtek ups even that was also unable to control. In my house in summer it reaches to low voltage, so ups start giving sound. So suggest me a good stablizer. I ve samsung lcd monitor 17", and nvidea gs8200 grafix card. Nw 500va or 1kva stabliser?

[thetechfreak]

IF you dont plan to get a fast PC in the near future in near future, 500 VA will do.

BTW, why dont you connect just the CPU to stabiliser?

An APC UPS has a very good inbuilt voltage stabilizer, buy that and get both features. I am using one with the below config.

[kool]

i bought a local stablizer of 500va input range: 90v-280v o/p: 210v-240v, but still it has same prob, whenever i turn ON AC in other room, it gets restart,

[saswat23]

Which PSU do you have. It seems like its a PSU problem.
Me too having the same problem. When i switch on AC, then volatge is quite low, but my UPS gives me backup so that i can switch off my PC safely.

@OP: At least a part of your problem may be due to a poor PSU (SMPS).

Voltage regulating devices like stabilisers and UPSes need a finite time to react to voltage fluctuations. The reaction time may range from a few milliseconds to as much as hundreds of millisecs. The computer PSU has to be able to store enough energy in its capacitors to keep on powering the computer during this period. A low-quality PSU may not be able to do that.

@ OP : pls give the pc config as has been demanded so that you will be rightly guided before you burn up a big hole in your pocket. also remember all the members of this forum will guide u to get rid of the problems correctly but if you stick to your own crappy ideas then it hurts us. An APC is a world leader in UPS but instead of asking things regarding that u have bought a voltage stabilizer which is a waste of money altogether and as expected your problem is not solved. u have used microtek,intex and all those are elcheapo ups.So please wake up and kindly put the PC specs now so that we can tell you exactly how to hammer the problem.

@OP, this problem never ends until u get a good brand UPS...
I faced the same prob when i was using zeb 600va UPS. Solved wen switched to APC 600va, which now costs 1.8K

i'm really sorry guys, i really wasted my money and my peace! Stabilizer is useless for me now, Rs.1300, i took UPS to service center, and they said "UPS is fine, may be there is earthing problem in power socket." But my electrician said earthing is fine. Now he is saying "to add direct single line from main power pole to power socket." guys please help me. Would I've to buy again new UPS? My voltage get fluctuates up to 130v. I'm waiting for your answer...,

its again INTEX smps. i'm writing here all details what i've got on its sticker-
POWER SUPPLY SMART IT 2045S+
450W, 20+4PIN, 2 SATA, 2HDD, 1FDD, 1FAN,
AC: 220V 50-60HZ, 5A
DC: +3.3V:30A +5V:29A +12V:18A, 12V:0.5A +5VSB:2A

PC Hardware Config:
Nvidia 512 mb GFX card, 17" Samsung LCD, 2 GB RAM, 2 SATA HDD of 160GB + 500 GB, keyboard, mouse, Bluetooth dongle.
In UPS it has 3 sockets where i've plugged:LCD Monitor, CPU, & BSNL Siemens c2110 modem.

I still suggest u to go for APC 600va...

Any strong reason? what would be its cost?

[pimpom]

The problem is a combination of poor mains supply, poor UPS and poor PSU. You can't control the mains supply, but you can do something about the other two.

I'm not familiar with the specific model of PSU you're using, but if it's an Intex, it must be a very ordinary one. It may be OK when the household AC supply is normal. But it's not likely to be able to handle the wild fluctuations you've stated.

As I said before, the UPS and the new stabiliser you bought need a brief period of time - maybe up to 1 second - while they adjust to the fluctuations. A good PSU will be able to use the energy stored in its capacitors during that period, but a poor PSU has too little stored energy to do that.

As other have suggested, a good UPS will help solve the problem, but you also need a good PSU.

Very True..

Just Rs.1700, i think my intex UPS was also for Rs.1.7k galti kar di yaar, INTEX le kar, but guys, plzzz assure me that APC can control fluctuation, this time i don't wanna money, else my mom will kill me for already spending for PSU+UPS+STABLIZER = 500+1700+1300 = Rs.3500

By d way, intex UPS works fine but during normal power and normal power cut, but unable to handle fluctuations.

^^Wat?? u bought new intex PSU??

no no. its old one in my cpu. m asking, which psu should i buy??

[MegaMind]

^^Again budget?

The cheapest solution for PSU is FSP SagaII 400 - 1.5~1.8k

Then u can opt for, APC 600va + FSP Saga II 500W/Corsair CX400 - 3.8~4K for both..

P.S : If u can find a CX400 get it eyes closed..

from where i can get latest prices for these 2? and APC 600va, is that all? or any specific model for APC?

How u know so much abt PSU+UPS? r u Electrical Engineer?

Corsair 400 is very costly, just nw i checked it on ebay.in Corsair CX400W 400 Watt Power Supply SATA-Ready SMPS | eBay

[dashing.sujay]

You can have a look at this- Cooler Master eXtreme Power Plus 460W – 2,400

BTW guys, can a simple UPS handle fluctuations occuring 10 times/min, from 100V to 300V. Its the situation at my home.

Check out PSU Prices

Just ask APC 600va.. To be more specific, the model is RS-600..

sort of engg.. But Trial n Error method..

CX400..
Get whichever suits ur budget, FSP saga II 500W/CX400/CX430V2..

Its a big NO to that PSU.. Extreme power series are not reliable..

Simple in the sense?

My bro has same pow fluctuation issues in his home..
His rig is,
C2Q Q8400 + 8600gt powered by CX400 + APC 600W and no issues whatsoever till now..

[dashing.sujay]

why a big NO?

simple means this APC RS600. I own it currently, but i dont think it will be able to handle that much fluctuation at my home.
