hello everyone,
bought this 2days before - UPS alone 2 months older
specs:
AMD fx 4300 @3.8GHz quadcore (not overclocked)
1x 4GB dynet RAM
mobo: asus M5A78L-MLX v2
GPU : xfx radeon R7 250 1GB ddr5
psu : Antec 550w (model : VP550P)
1TB seagate HDD

UPS: 600VA (360W) intex brand- it also have AVR for voltage stabilization (note: i bought this UPS before 2months for my another pc nd just connected to this new pc now)

My problem is, whenever i play games like battle field 4 or 3 & even Wheel man(2009) for 20 mins, it automatically turns off without proper shutdown.

some of the reasons i guessed :

1. i noticed my GPU getting overheating upto 80degrees. considering this may be a reason- so i lowered game settings -now temp goes down to below 65degrees , but again same problem exists. ->( this may not be problem bcoz it went high upto 80. so at 65 it shld not turn off)

2. in our area there is regular voltage fluctuations -considering this i also disconnected UPS from wall plug and tried it by running ups battery, :( no use -same problem.

3. i am sure its not PSU fault , because its 550w is more than enough -> i not even connected dvd drive-> only cpu,GPu, motherboard and harddisks and a fan uses power from psu.

4. the last chance for being a reason for problem is UPS,. but i dont know is this the real culprit. you all shld help me, as its only 360w . untill idle and small load system works well..but while playing games , load gets increased and more power is consumed , so really my UPS cannot hold it?. is this overload auto shutdown?


this is my question: is UPS is problem for me?
whether i want to change to higher output UPS ? or is there any other reason?.

YOU people pls pls help me out.! :(

i also add that -> whenevr my pc goes off , there is sound in UPS and lights in my room flickers.

At 100% load/stock freq. the FX-4300 can demand as much as ~140W. It only has a TDP of 95W however. Idle doesn't matter.
The R7-250 has a TDP of 65W. Even that can spike occasionally when stressed.

If you are looking for an on-paper estimate of your system's peak power demand, use one of the PSU calculators on the web: http://www.extreme.outervision.com/PSUEngine

But as we mentioned above, it appears that your UPS is under-powered.

More important than the wattage, what is the amperage rating of the +12V rail? You show the classic symptoms of too small or poor quality PSU. Can you test it out w/o going thru the UPS? That could well be the issue too since it is under rated for the system you are using.

80C is not over heating for a GPU. Warm. yes. But not dangerous.

thank you for your rply.:) for +12v , its 30A .. i thought its okie and enough ! my vendor also told the same.! but i dont know about this. i blindly bought what he said.! so really, is this not capable to run GPU? feeling confused .!:(

and you cleared me its not due to overheating since 80 is just warm,-> so this mean i can run my game in higher settings :) happie!

for testing without ups -> i got serious problem in our area , for every 5 to 10 mins there is voltage fluctuation -> that may lead to switch off.!. but i can do what you said ( i can run my pc from home UPS). but its just after knowing your answer for PSU.

waiting for your rply.! thnk yu

My mistake on the PSU. I mis-read the PSU as being 360W. I guess I missed the Antec 550W in your list above. The Antec is a good unit and should be more than enough for that system. But the 360W UPS may still be the issue*. If you have another one to test with, that would be the thing to do since power is that erratic in your area.

*the 360W rating is no doubt at line voltage (120V, 240V?). Whatever your PC is using in the way of DC watts, you can figure it will be higher on the line side by a bit. The AC side of the PC's PSU has to deal with inductive and capacitive reactance that will add to the power actually used. It is called power factor.
 
There is also the possibility, with so many voltage fluctuations, that the battery/batteries in the UPS are not getting fully charged and/or are worn out already and need replacement.
I went through something like this a year ago and it drove me crazy until I checked out my UPS.
Just a thought.

@clutchc:
I like your new avatar? why the change?

happy to hear-> my PSU is not a problem .! :)

so , since my UPS is 360W, this may be the reason. its output specs are:
AC voltage regulation:230VAC+-10%
AC mains frequency :50Hz+-1%

input specs: voltage range :140VAC-300VAC
nominal voltage: 230VAC

as i am not electrical person, i couldnt understand completly. but now, i ll test my pc by connecting to home UPS (it ll hold upto 5 to 6hrs) and i'll post results after hard gaming for 1 to 2hrs.! * thanks for your idea :)

@nostall.

thank you for your rply.!

ya , that may be a reason ,but as i said already, i just disconnected my complete pc from wall socket and played games->but its just happen again :( same problem.. so i think apart from voltage fluctuation, something played culprit role.!

well , now i ll disconnect my pc UPS and ll run through home ups.! lets see what going to happen.!

thnk yu.!
 


I just read that you disconnected your PC from the wall socket and played games. Where you just using the UPS?
If so you are making major errors and mistakes.
1. The UPS is designed to power your system momentarily - 5-15 minutes at the most and with your 600VA/350W unit probably only 5 or so minutes. Enough time to shut down the pc in a power failure.
2. You haven't told us the make or model of your UPS's, but most also serve as line conditioners (I think that is the right term) so that the power the power from the wall is cleaned up and reaches your PC power supply at exactly 220 volts (120 in US and Canada) and at 50 or 60hz; with the power fluctuations you mentioned that means your UPS is really working all the time.
3. Most if not all UPS devices have a method of testing them by using some button on the unit; you do NOT test them by unplugging them from the wall because:
4. You eliminate all grounding for your system! UPS manufactures tell you in the manual, "Do Not test by unplugging the UPS from the power source as this can DAMAGE the UPS and your equipment."
I had a friend destroy his $400 (USD) UPS unit by doing this, and it took out two sticks of RAM
So before you ruin something, shut down your PC through Windows, make sure your UPS is plugged into the wall, and let that UPS charge up for a good 12 hours - during which you can dig up the manual and find out how to properly test the UPS.
If you run the test properly, and the PC shuts down immediately (in other words it fails the test) then it is more then likely the battery/batteries for your UPS. If it passes the test (when you properly run the test the computer should continue running until the test is complete, and afterwards) and you still have the problem you described (game/pc crashing), then we can trouble shoot other things, like the Power supply.
Hopefully nothing has been damaged so far.

@nostall,

sorry , forgot to mention that i just switched off wall socket and used UPS battery for almost 5 minutes -> due to overload or smeother reason it shuts off, then again i switch ON pc with same condition . it also runs another 5 minutes and shuts off. so we cannot say that battery has no charge. so ,yes i guess its due to overload .!

and i have some doubts
1. what is the power consumption for CPU (fx 4300 @3.8Ghz) @ loaded condition and idle condition?
2. what is the power consumption for GPU (xfx R7 250 1GB ddr5) @ loaded and idle condition?
3.and total consumption for mother board and harddisk ?

if the total consumption (CPU+GPU+mobo+HDD) is above 360w ,my PSU can handle this since its 550w (12v~ 30A), but can this UPS handle this?, since my UPS is just 360w

and i think problem is with 360w UPS, bcoz now i keep out this UPS and directly connected to home UPS (Exide 850VA ) it just runs smoothly without any sounds and yeah without restarting ..! :)

so i decided, the problem is with PC 600VA(360w) UPS...so am going to replace with 1000VA. hope this ll solve my problem.!

if i am wrong , just mention how to solve and what to do.! i ll definitly try my best .!

keenly waiting for your rply.! hope yu ll clear my above doubts.! :(
