PC keep restarting. Do I need power stabilizer?

[crius.black]

Which will be good stabilizer for my PC?

Hi...

My PC keep restarting in every 5 - 10 minutes. I tried to troubleshoot everything including disabling "auto restrat" option and formatting my PC and doing clean install. Still the problem is there.
Then I suspected power fluctuation issue. So I tried to connect my whole PC system in my neighbor's house and same problem happened.

Later I connected my PC at my uncle's house in another area and it doesn't restart. So temporarily I came to conclusion that it is may be because of power fluctuations in my area.

The issue just started since last 2 months. Complained to electricity officials but you know how these organizations work in India.

Below are my PC configuration.

OS: Windows 7 Ultimate

Intel i7 6700k
Asus Z170 Maximus VIII Ranger
32 GB G-skill Ripjaws (8GBx4)
240 GB Kingston SSD
4 TB WD HDD (1TB x 4)
4 GB Asus GTX 960 DDR 5 Graphics Card
Heatsink liquid Seidon 120m
LG DVD Writer
600W Cooler Master SMPS

22" Dell S2216H LED (2 Monitors)
Creative SBS A-355 2.1 Speaker
Wacom Pen Tablet
APC BR 1100CJ-IN UPS
Keyboard Mouse

My UPS is in great condition and in power failures, give 20 minutes of backup. But it can't prevent restart. Also I keep all my drivers up to date.

The total power consumption of my PC comes around 1200W I guess. Do you think I need a voltage stabilizer? If Yes, then which is best? My budget is around 8K INR.

Do you get any indications while restart ? UPS beeps, light fluctuations. It could be something related to your hardware as well. If there is power line issue, switch on the lights and look for some flashes, blinking etc. Otherwise, something might be wrong in your motherboard or similar.

Thanks for the reply. But same PC doesn't restart when I shifted it to another area in my city for testing. Yeah there are light flashes at different time in my house. Whenever the PC restarts it doesn't give any indication. It just restarts like someone switched off and then switched it on.

1) which cooler master PSU model no ? and how old it is ?

2) did you have voltage fluctuations in the past as well ? and no restarts back then , or are they occurring now only ?

3) restarts happening at idle as well or during gaming only

Were you using the same UPS ? How long did you test ?

1. Cooler Master RS-600-ACAB-B1
2. Yes, Voltage fluctuations were in the past too. But no restart then. It started just since last 2 months.
3. It happens every time. Whether it is idle or I am working on it.

No. In other area I connected the PC directly to the power supply. Not UPS. But, in my home I tried disconnecting UPS and connecting it directly to the power supply and it restarted then too.

If the same PC does not restart in another area with same ups then a probable reason might be some issue in changeover time of either ups or smps which is not able to keep up with fluctuations in your area but would work fine with a constant electric supply.

Did you check your power point ? Get an electrical guy to have it mentored.

Another Area:
No UPS. Direct power supply. No Restart.
My Home:
With UPS. Restart.
No UPS. Still Restart.

Checked Power supply. Tried to connect in another power supply in my home. Still restart.

Power point is fine. Tried connecting same setup at another power point in my house. Still restart.
Also in my neighbor's house, it restarts.

from the description i am 70-80 % sure that this is because of PSU .. your model Cooler master B600 uses a Capxon primary cap ( bad quality )
Cooler Master B600 ver.2 review door -The_Mask-

, although you didn't mention how old it is , i am guessing it is 2-3+ years old already , it has probably degraded and lost it's capacitance now and isn't able to provide a long enough hold up time to keep your PC working while your UPS takes time in switching and adjusts when there is voltage fluctuation .. while previously it was fine.. your PSU also takes input from 200-240v only

This is common issue with Corsair VS as well from what i have read..

in another area where it didn't restart , voltage is constant and above 200 v , so hold up time doesn't come into play...

does it restarts everytime there is a voltage fluctuation ? or it sometime does and sometimes not when there is voltage fluctuations ? i mean does it keeps on working sometimes when there is voltage fluctuation..

to confirm before making an expenditure can you arrange a different non faulty power supply or UPS from friend somewhere for testing ?

1. The whole build is 1.5 years old.
2. Sometimes, occasionally it holds up till 25-30 minutes.
3. I called APC (UPS guys). The technician came and checked the UPS and found it perfectly working.
4. I have uploaded my restart/shutdown log file obtained from You can see how frequently it restarts. Due to it, PC remains idle since last few days.

PSU seems to be the culprit , if you can arrange somebody else's PSU then that would be good .. RMA this PSU , say it restarts PC on power cut with UPS , and previously it used to work fine for 1.5 years and never had issues

in the meantime try removing all the 4 hard disks and GPU from PC . run it bare minimum on iGPU , at stock , only connect PSU wire to UPS and no other components like monitor, speakers etc .. and see if it is able to decrease the frequency of restarts..

you can try repeatedly switch on and off your main AC switch to which UPS is connected , 10 times .. see how many times it restarts then out of 10

The PSU is poor quality anyways and not good for your system for long term , better change it

Thank you sir. I will do the same and let you know my results.

 

[crius.black]

Also if you can suggest me the suitable PSU for my system, it will be really helpful.

don't call me sir bro

if you can spend around 8k , then Corsair RM 650X .. it has 10 years warranty ( though confirm once from corsair india if it's 7 or 10 years in india).. so it's worth the price , buy once and forget about PSU for next 7-10 years..

otherwise Corsair TXM if your budget is tight and you are ok with it being loud...

but before buying first please check your system with somebody else's PSU , just in case if problem is something else other than PSU

Thank you. Sure. I'll check it first and let you know here.

 

[sling-shot]

What happened man? We are all curious to know.

Hey... Sorry guys. I was very much busy with some heavy edit vfx work. The issue is resolved. The culprit was PSU. I changed it and upgraded to 850 watt PSU. EVerything works butter smooth now.
Thanks to all the members and specially gta5 who took their time to discuss it here. Cheers !
