My computer crashes ONLY when i play Battlefield 3. I'm thinking it might be because my psu can't deliver enough power to the GPU but i don't know for sure if it's the psu so i'm asking you guys for your thoughts about the whole matter.
That's after the crash, I can't do anything but to hold the power button until it shuts down. Another thing is that the gpu fans ramp up to 100% and stays on 100% until it's turned off
This took some hunting but here is what I came up with. I could not find the exact card you mentioned but this one only differs in the fact that it is not an OC edition. The site states a minimum of a 500W power supply. This may not be enough for the card you have if it is over clocked. Here is the page I found on Newegg.com.
If you have and know how to use a volt metre you can check the output of the various connections from your power supply to insure they are correct. This is also a great page for checking power supply requirements. Best of luck and let us know how it goes.
I tried filling in as much as i could on the website and it said Minimum PSU Wattage:336 W Recommended PSU Wattage: 386W Overclocked CPU Wattage: 121W
What i would like to know is if it crashes because of insufficient power or if there is something else lurking. 386+121=507? So i need a new psu i guess? Should it not crash when i play Planetside 2, LoL, Dota2 or Cs go all maxed out? Im confused. When a computer generally crashed because of insufficient power does it do like i described or does it just shut down? EDIT: I will be back tommorow, i have to sleep now. Keep posting if you got any suggestions and i'll look back tommorow!
You shouldn't crash playing any of those games, especially Cs, with that powersupply wattage. If you have a multimeter then you can check the voltages by putting the negative lead on the groud terminal(COM in the diagram) of the PSU and putting the positive lead on the terminal you want to know the voltage of checking to see if you are getting the correct voltages. To turn on the PSU without having it plugged into the computer you can use a paper clip by bridging the PS_ON# to a COM terminal (ie put one end of the paper clip in the PS_ON# terminal and the other end into the COM terminal and leave it in). Note you should be getting the exact voltages shown + - 0.1V. Otherwise your voltage regulators aren't working right.
I know that OCZ sometimes has problems with defective voltage regulators. If I were you I would return it and get a Seasonic PSU preferably a 650W unit. If you plan on upgrading your rig in the future by adding another graphics card or water cooling getting an 850W would be advisable(also the extra power helps adding extra fans/HDDs/SSDs). Remeber to get an 80+ certified PSU.
I'm thinking it probably is that your computer is drawing more power than your PSU can handle. The only reason I say that is because the Bulldozer CPUs are huge power hogs, especially when stressed, and BF3 is coded to use as much of your CPU as it likes. So that in combination with the load from a descrete graphics card may very well push it over the edge.
^Vortex may be right.(I am not an amd cpu guy) Maybe the overclock on the cpu and graphics card is pushing the limits of the PSU. Try without the OCs and see what you get.
So if i wanted to clock my cpu to 4.4-4.7ghz and my gpu further from 975 to maybe 1000 and maybe overclock the memory a bit what PSU would i be getting? I've been looking into these 2
Antec Earthwatts EA-650 Platinum 650W or XFX ProSeries Core Edition 750W PSU you think any of these will be stable with the desired overclocks?
I couldn't get those 2 since they were not in stock so the 2 im looking at getting now is ANTEC HCG-620 620W or CORSAIR TX 650W V2. I've read some reviews and they said the Antec is quiet while almost all the reviews on the Corsair said it was pretty loud, Im leaning towards the antec but i just wanted to check here once more to see if you had any last words/advice.
I would go with the Corsair PSU. They tend to have much better build quality than Antec. I suggested an Antec PSU to a friend of mine a couple of years ago, and I don't recommend them anymore because he installed it, turned on his computer, all the lights in his apartment went out, and the PSU fried itself. I've heard a lot of bad stories concerning Antec PSU's since then too. Antec probably still makes decent PSUs, but it seems like they have a higher failure rate than Corsair.
