UPS giving trouble

[ajayritik]

Just power the smps through ups and disconnect all the loads like hdd, motherboard, Gpu and rest which are connected to psu.

If the ups fail then try hooking up only your monitor without the psu with ups. If it still trips then ups is faulty otherwise throw your psu out of your cabinet.

Thanks Much! Will try this out. But as I said will have to wait for some voltage fluctuation. That is when the problem triggers.

by config they mean to say your desktop computers components
what CPU do you have
hom many Hard drivers
which graphics card is intalled
I would suggest you to buy a new UPS and Power supply for your computer.

CPU= Core2 DUO 2.13 GHZ
Motherboard=Intel G965RY
Onboard Graphics
One USB 3.0 PCI Card.

You can simulate the Voltage fluctuation, by switching ON & OFF the mains either from the MCB or from switch board.

Make sure, you have a spare Fuse lying around.

I'm also have the same problem. My PC also get restarted during power cut . I also found out the solution. My UPS doesn't have the power to drive my computer at full load. So I upgraded my ups from 600 VA to 1100 VA. Now the system works fine. May be this will help you.

Getting an APC1.1Kva is not always the solution here. Your case might be different from OP, since the config mentioned by OP is not so power hungry & addition of few more HDD inside the cabinet won't load more than 3-8watts into the total power consumption.

@OP : Are you connecting your monitor to your UPS ?? If yes, which Monitor ?? Post the monitor details too. If its a CRT, then either you have to live with it or upgrade something bigger.

I wanted to post this and you already suggested the same. Thanks much. But sorry I'm very noob when it comes to electricity terms etc what about the fuse? Why would I need that for?

Yes. I'm connecting my monitor which is Dell. Dell ST2220 M LCD Monitor. From yesterday night I had one power cut and twice voltage fluctuations and 2 out of the three times system has restarted. Only once it hasn't.

"Fuse is a piece of wire of a material with a very low melting point. When a high current flows through the circuit due to Overloading or a Short circuit , the wires gets heated and melts. As a result, the circuit is broken and current stops flowing"

At Max your LCD/LED Monitor can load upto 30w, which is ok upto some extent.

From your Config details, i feel the total power consumed by your PC will be roughly from 200w - 300w [depending on the loads & usage]

Should I try this?

Should I try this?

Yes..its absolutely safe. But becareful not to wear wet clothes or wet hands, while performing so. Better to wear a leather shoes/chappal or any isolator between you & your feets touching the ground or floor.

This is what you had suggested right?

 

[d3p]

Yes, Connect only the PSU to UPS & disconnect the rest from it.

Ok will try this out and let you know

Arey ico tu kahan ka rehne wala hai? Delhi ya Bangalore. Aur tere avatar mein Prem Chopra kyu hai?

 

[ajayritik]

I'm little wary of trying this. Is there anything else that I can try?

Use your Switch from the switch board.

Frnd, how old is ur ups and its battery.....
i think ur ups battery has ran out and is unable to bear instant fluctuation.....

I got this troubleshooted with online UPS customer rep and he was saying problem may be with the Power supply i.e. SMPS rather than the UPS. The battery was last replaced over an year ago.

 

[Ashok Verma]

Ok... Thats good... And u didn't mentioned u replaced battery last yr. thats y i doubted it....

Now ur problem solved...!!! Enjoy.... Which psu did u own now...?

Ok guys just wanted to check if any more people out here can help me on this.

Problem:
1.Computer restarts whenever there is a voltage fluctuation.
2.Most of the time when power goes computer restarts and gives back up.

Problem:
1.Computer restarts whenever there is a voltage fluctuation.

Obviously, Either your UPS is faulty or SMPS. Hence can't able to handle the power required to keep the PC on.

Problem:
2.Most of the time when power goes computer restarts and gives back up.

^ This..I couldn't understand. Computer Restarts & Gives Power Back Up ??? WTF !!

If you mean, your computer restarts due to fluctuation in power source. Then there's an option in BIOS to Turn Off "PC restart due to Power Failure".

I had the UPS shown at an APC Service center. Initially the guy said the problem could be with transformer and the battery but later confirmed that the problem is with the battery and it would cost Rs 1300. Should I go ahead with getting it fixed or should I buy a newer UPS.

 

[ajayritik]

Guys I had the UPS disconnected and had the PC connected to the power source via Surge Protector and when there was a voltage fluctuation my PC restarted. Could this be due to SMPS?
