Ups causing pc to restart

[MD Utsho]

I'm facing a weird problem for 2 days.
UPS is making clicking noise and pc restarts. but when voltage spikes and ups makes clicking sound doesn't affect the pc. but suddenly ups making that sound and pc restart without any voltage spikes.
i'm not sure what is causing this problem. is it psu or the ups? 
this ups and psu is 10 month old. 
Currently i plugged in the cpu directly to the wall socket to understand is it psu or the ups. 
but anyone knows what is causing this problem?

Had an issue before with my Cyberpower UPS having my computer turn off without warning. Ended up RMAing the UPS, and they got me a new one. My guess is that something inside the UPS is possibly going. If you can contact the company that made the UPS or the store you bought it, depending on where you live depends on the process to do an RMA.

Clicking sound is probably a relay. I would just RMA it. If you are in Europe you should have 2 year minimum warrany.

How about some info on everything involved?

yeah i have warranty, but don't know if they're gonna take it. I'm from asia, and this happening for 2 days not all time time, it happened 3 times in 1 hour and i'm using pc all day long maybe 7/8H in a day.

Yes i have to contact with the retailer. but not sure what i'm gonna show them. they don't take it if it looks alright. i use pc most of the time maybe 7-8h a day, and it's happening for 2days and it was fine all day long only happened 3times in 1 hour, and again now i'm using it for almost 1h and the pc is not restarting.
i checked psu is fine, it's the ups. i plugged the cpu to the wall socked and the monitor to the ups, in that time ups made 2 clicking sound but the monitor didn't turn off, i guess it's only 20watt maybe that's why, but for the cpu i'm using a rx 590 GPU. and it can't handle that powerdrop.

Hey, today i checked most of the things, i'm now sure that it's not because of my psu or the fridge connected next to the wall socket for the ups, 
it's something problem with the voltage or the ups itself.
you said that you had the same problem, was it all of the time ? it's only happening after evening, it's fine in day time and midnight.
So what do you think? is it UPS or the electricity? 
 

[MD Utsho]

It's not a common restart problem that happens when powerdrops.
It's happening when power is online no voltage spikes (maybe) but the pc restarts after ups making a clicking sound.
I know the sound of the click of voltage spikes, but this time it's kinda different, i mean sound is low and then the pc restart. 
so i need to know that if it's casing because of the electricity or the ups itself having some problem. 
it's happening for 3days.
not all the time, i noticed after 6AM. 
I usually use pc after 2PM to 2/3AM maybe.
for the first day it happened 2 times in 1h, 2nd day 3 times in 1 hour, and today 3times at 6PM and 8PM it was fine all day long, it's fine now.
i can't even use warranty if i can't show them the actual problem. if it's ups or the electricity 
What should i do? 
Thanks in advance

which exact UPS is it, and which power supply is in your computer?

 

also, does it interfere with other devices (display, router/switch, light bulb, etc) when connectef to the UPS?

[Windows7ge]

Does the computer still do this if you plug it directly into the wall? If not it's probably the UPS. If yes it's not.

 

Some PSU's don't like square-wave which is what most cheap home UPS's operate using. This could cause the computer to spontaneously shutdown or restart.

It's powerguard 1200va UPS. And i'm using thermaltake 630W modular psu.
it's only connected to the cpu and monitor.

i'm using this pc for year's it's was fine, and i wanted to test that that's why connected the cpu to the wall socket, it was fine, used pc like that more than 1hour. 
but i think it was too late, like i said it happened between 6-11PM.
after using it from wall plug for 1h again i connected it to the ups and used it for almost 4h. and still not restarted happened 
also today it was fine 2-6pm then the restart happened after that clicking sound, again another 2 after 8PM.
still i'm using pc and it's fine, no restart is happening so far

If you connect the computer to your UPS then unplug the UPS from the wall what happens?

Ups is fine here, it's working, battery backup is fine, also it can handle voltage spikes, cause i can see the light's brightness is jumping and ups making click sound.
but when pc restart's and i hear ups making a low clicking sound but the light isn't jumping. 
SO that's why i'm confused.

spelling mistake

Well, I would suggest seeing if other equipment plugged into the UPS do anything strange when it clicks. If so you will probably want to change the UPS.

Well can't think about other thing's specially a light which can actually wait lit for some MS when the main power is turned off. i'll see what i can do. 
but why it's happening after evening? not in day time and night time? i'm really confused here, if ups has some problem it should do this all of the time even when the voltage spikes i can see it's handling the power.

my guess is that the power supply cant handle the very short drop of your UPS kicking in, or the UPS is taking exceptionally long to kick in.

 

there's one exact series of EVGA power supplies, for example, that will drop out if it loses just one entire sine wave from the wall. i'm not well versed on thermaltake's quality, past that they dont have a very good reputation as a company.

 

so.. what to do? well.. depends which one of the two issues it is, but your solution is gonna cost money.

but why it is happening suddenly for 3days? it was fine for years, the ups is 9month old maybe, and it's only happening after evening, now i'm using it for 3/4h straight. no restart so far also voltage spiked couple of time but it was fine, 
but only happening between 6-10PM i guess. 
can this happen because of low voltage between that time?

it can be that recently voltage in your area during peak times drops just low enough, it can be that components in your UPS have just enough wear to dip a measurement below the triggering point, it can be that your power supply aged to the point it's just not quite capable of jumping the gap, it could be that windows or driver updates have caused slightly higher power consumption on your pc, etc etc...

 

there's a LOT of variables here, and without having experience with your situation i wouldnt be able to place any close bets on the exact source.

Yeah i understand, also i couldn't find anything like this problem in google, that's why i posted this, 
maybe i'll check another 2/3 days if the problem still appears after evening maybe i'll contact electricians, but if still appears in another time then i have to guess it's because of that UPS, PSU is fine i guess not a great quality psu but still ups never made that sound without voltage spikes but now it's doing that and causing my pc to restart.
Thanks by the way for your help.
oh and another thing since i'll test for another 2/3 days and my pc keep restarting directly will it affect my hardware ? or damage the whole system other then corrupting the data ?

Some UPS units give you the ability to adjust the high/low trigger voltage for when to switch to battery. It's possible there's a voltage droop in your area at those times and the UPS isn't switching over causing the computer to shutdown/restart possibly due to aging/pre-mature failure.

the worst it can do is kick out your system while doing windows updates, i suppose.

if the UPS clicks, it's switching over.

 

also, i'm taking a wild guess that OP's in a 230VAC area, based on the model of UPS, so he'd have to drop QUITE low to make a power supply conk out, which would be very noticeable trough the house.

Windows update is actually turned off.

Yeah even when i turn on AC the voltage jumps, but it doesn't cause the pc to restart, i can hear the clicking, but maybe something is happening in that time that don't cause the light to jump, but the ups delays to change.
