Greetings,
When the electricity switch between "Cherke and Eshterak " or when it disconnect my PC restarts
I use a very good power supply ( Hawk - 1200V/A ) so any idea what the problem could be ?
Note 1: Sometimes when the electricity switches or disconnect the PC doesn't actually restart, it just half turned off, i mean i can still hear the fans rolling but there is nothing on the screen and i have to turn it off then on
.
Note 2: Sometimes when electricity switches or disconnect the PC keeps working normally.
I can say that this problem occurs only on High Gaming
After I asked many friends about this problem and all said it's an UPS failure, I changed it to ( BEST ONE - 1200VA)
Still having same problem !!
My rig :
AMD FX-8350 4.0GHz 8-Core Processor
Asus M5A97 LE R2.0 ATX AM3+ Motherboard
AMD Radeon R9 Gamer Series 8GB (2 x 4GB) DDR3-2133 Memory
Gigabyte Radeon R9 290 4GB WINDFORCE Video Card
Corsair Builder 600W 80+ Bronze Certified ATX Power Supply
Any one knows a solution ??
Is the power supply causing the problem?
Thanks in Advance for Replying

Best One and Hawk are generic brands, meaning they're most probably not really 1200VA.
Get something that's a well known brands. Like PCE, Tripp-Lite, MGE etc. (I'm selling a PCE 1500VA (660W) for $120 if interested)

I would say it's a Mobo fault, I have the same problem with my Intel board for years, I changed PSU to XFX, GPU,case...nothing changed!
So the only part that could do that is the mobo.
I remember it begun after my first Bios update...
Check if you have Wake on Lan ON in your mobo options before concluding it's a faulty mobo like me :)

1200 VA my not handle the 600 watt as @AvoK95 said, I don't think it has anything to do with the mobo.
I had the same problem when I had a small UPS and it just failed when I was playing games and the electricity goes off.

Have you changed the power supply unit of your PC?
I guess when there is a power cut, there is a very small change in electricity supply voltage to the computer. The power supply should normally be able to handle such little change, but in your case maybe it is not and it needs replacement.

It is a UPS fault.
Sometimes it's the low switching time the UPS has to switch from one power source to another or to battery.
It can be the power supply unit located in you computer case. If it is a generic one then buy a new BRANDED psu.
Check your bios settings and look for an option about starting computer after a power failure and disable it.

@AvoK95 and @aliessayli2 @rolf I am a little bit confused about the solution you said. I think it Can handle it normally I can unplug the power from the UPS and start the pc normally with high gaming ( I Tried It )
I looking for what @vegetaleb @m_zeid I Checked my bios settings and this what I Found but I'm not familiar with any.
I think the solution is in here ! :)

and then I found it is not in here :(

If you have a 600w PSU it DOESN'T MEAN the power consumption from the outlet is 600 watts !
IT MEANS that this PSU generates 600 watts of power maximum.
To calculate the power consumption, 1st your PSU's efficiency is 80% at it's best & power loss is 20% minimum.
Power consumption = Generated power + Power loss
Power consumption = 600 + 20% = 720 watts
"IF the PSU is on max load @ best efficiency"
But your PSU isn't gold certified which means the efficiency will drop on high loads and lead to consume more power from the outlet.
If efficiency drops to 70% @ max load, you need 780 watts on the outlet.
If it drops to 65% @ max load, you need 810 watts on the outlet.
Accordingly, you need an 850W UPS (1700VA @ PF of 0.5) to handle your PC "Case only" @ max loads such as heavy gaming.

Bluntly saying i think after changing your UPS while the problem remained and assuming you had the computer for a while before this problem started then i would suggest that the problem is in the PSU (specially with the good electricity in Lebanon)
If you cant change your Power supply at the moment try a trial and error method ... take your UPS to your friends and try it on their PC or bring their PC to your house just to make sure

@mohammaedSF
You're the man !
I will try the 1700VA and I will reply to you

@Nam thanks for the reply!
pretty sure what mohammad said is the problem because some times when I am not gaming the UPS can handle it

You're welcome :)
To find out the actual consumption of your PC get a clamp type ammeter and find the highest reading while gaming heavily or while running heavy benchmarks capable of pushing your CPU & GPU to 100% load.
If you read 4A for example, 4A*220v = 880 watts, on a UPS with a power factor of 0.5, 880 / 0.5 = 1760VA

had same problem, simply bought a prolink ups, with higher power capacity, I suggest prolink, have 2 and I cant complain , hope this helps

Swap the old PSU with a new PSU (80 Plus Gold Certified) + a New UPS ; I think such problems a hardware drilling approach is recommended ; Unplug hardware with another hardware (one by one) starting from the PSU to drill down to spot the cause ; so recommended to give it for a reliable hardware store.

I Solved the problem by getting and 2000v/a ups :) lol too easy
I would thank all who replied to this thread :)
