Windows 7: PSU or UPS Problem? HELP!

I dont understand one thing.. when i check by throwing the breaker down (which as the experts say that it simulates a power outage to check the UPS) nothing happens and the PC keeps on running during game where the GPU+CPU+PSU is on full load and stress. I even checked the GPU load with the help of GPU-Z and tested several games on it like Assassin's Creed: Brotherhood uses GPU 40% to 60%, Bulletstorm as well, Super Street Fighter IV uses on 25% to 30% GPU Load and PC dont restart on them. However Crysis and Metro 2033 especially uses almost 100% GPU in some places and it's average load on GPU is 90% and above. So lets say Playing games like Crysis and Metro 2033 which are Hardware hungary apps uses the Maximum power off the system in easy words the PSU is at it's Peak Load.. but i remember exactly the day i installed this new Graphics Card AMD 6850 i ran Crysis 2 times and played it until the Power-Failure happened and PC did'nt restarted.

Also i do remember when i installed Assassin's Creed: Brotherhood my other applications started to give me errors. Yahoo Messenger gave me error and some other application was crashed so i updated my Windows and those errors and crashes were gone and fixed but later after several days when i ran Crysis and power outage happened this problem started.

So is there a possiblity the Windows has something to do with it after updating it? Does throwing breaker down from the DP really simulate an actual Power-Outage or it has to be a proper real power failure/outage from the Grid. What is this Mystery?

By pulling the plug for the UPS from the wall is fine to simulate a power outage.

It makes no difference. Your battery backup will kick in when it is not getting power from the power grid. It doesn't matter how you disconnect the power to test.

You never mentioned the brand of UPS you have. Did it not come with software? I use APC UPS's & the better models come with software that gives you good info - such as the current load you have connected, the estimated runtime, the input voltage, etc. You may also initiate a self-test to see if the batteries are in good shape. It takes a lot of guess-work out of the picture.

It is possible that since you have a power grid that goes down regularly it could be spiking as it goes off. Idk for sure but the UPS might be goin past its input range ( usually they can take a range eg.110-125V, and if you give it outside that range it would most likely shutdown all power to protect itself.

That would not be simulated by flipping the breaker but would cause problems if its spiking too far.
Not for sure but worth a look

My UPS is a SVC-1200VA it's a chinese made but well made unit and it's quiet popular here. It has AVR and <10ms of transfer time and other features etc. APC are very expensive here and i'll have to pay 3 times the price of SVC for 1 1200VA APC unit

@ kool1zero
You could be right and it's happening something like you mentioned but idk how to check problem and it only happens when power goes off by the grid and only when my system is running some game which uses GPU @ full load.. never restarted by pulling the plug out and throwing the breaker down i checked more than 10 times randomly in past 2 days... is there anyway to check it and fix it?

If you wanna see if it is spiking you could use something called an oscilliscope and you could try maybe just put a surge protector before your UPS. I'd try the surge protector first. Also since your ups has a powerstrip as part of it you should only use the one plug on ur surge protector

Bilal, what do you have connected to your UPS? I have my PC, Cable modem, router, and monitor on the back up outlets. I have a 750VA APC BackUPS unit set to shut down after 5 minutes of power outage.
For pure PC protection you don't need to have speakers, printer, or scanner on back up. You would do well to get a APC, Tripp-Lite, or CyberPower unit.

First of all sorry for late replying coz i just sent my motherboard in warranty as it has voltage sensor problem and got new one as replqcement but i did'nt assemble my pc yet. Also bought new PSU Cooler Master GX550w 80Plus Brone today in order to provide better and clean power to PC

@Britton30
I'm only using LCD, PC and Wireless Router which are plugged in a Power-Strip which is connected with the UPS in 1 Power Outlet although the UPS has 3 Outlets but im using one due to Power Socket that is 7 feet away from Computer not using anything else.

@kool1zero
I'll try with it too but i did not understood little what to do about Surge Protector

No worries about that. My suggestions were more of a technical nature.

I think with a new mobo and a slightly larger and better quality psu you're set
