Hey Nice People of Tek Syndicate I semi urgently need your help.
I built my pc last week; it went well except i may have broken a stick of ram, but that's not important.
I have a 550w OCZ fty psu
x1 HIS iceq turbo HD 7870
AMD FX 8320
8gb ddr3 Gskill ripjaws
Asrock 990fx extreme 3
3 case fans
and a Coolermaster TX3 evo, obviously with the fan.
My Graphics card drivers stop responding all the time. I read up on this and aparently its most likely i dont have enough power going to my gcard.
The psu is 83% efficent.
Do i need a higher wattage psu or what?
that psu is a not a 80+ bronze or better certified psu, so that could be an issue.
Normaly for a setup like this a 550W 80+ bronze should be enough to work well. but a decent 550W 80+ bronze/gold is something i personaly recommend. but which AMD drivers did you installed?
p.s i dont move this topic to psu section, because this could also be some other problem, not psu related!.
I hate ocz products with a passion high fail rates on EVERYTHING thay put there name on.
550w will be pushing it a little if you have overclocked your cpu and gpu
The XFX is a good solid psu (basically a seasonic psu)
Why recommending such large PSUs? This man's PSU is way more than enough. It doesn't mean it's a super high quality unit, but it's more than enough. 650W for a single 7870 is pointelss; you could run two or more 7870s off of that PSU.
Also, efficiency has nothing to do with the delivery of the power. You could have a 100W 80+ Titanium PSU trying to power a Titan Quad SLI config and it wouldn't work, but you could have a 1600W non-80+ PSU powering Titan quad SLI and be just fine; the efficiency only impacts how well it converts AC to DC, not how well it delivers the rated wattage.
i see that i had recommend the wrong psu
i ment this one: http://www.amazon.co.uk/ProSeries-550W-Power-Supply-Edition/dp/B004U6S1P6/ref=sr_1_3?ie=UTF8&qid=1375109998&sr=8-3&keywords=xfx+550W
like i said in my first post, a 550W 80+ bronze should be fine. but i can tell you that a 80+ bronze certified could realy help in therms of stability, i had a CM GX750W lite psu, was not 80+ bronze certified, and it was realy struggeling with my 7870.
But i personaly think that, that there could be some other issue. he did not ansewr my question, about which AMD drivers he installed.. i recommend to install the AMD 13.4 Driver. because i think its not a psu issue.

Sorry i was afk. Thanks for the help.
Im looking into returning my psu and getting something else.
I think its an issue with psu because no.1 I added up all my components http://support.asus.com/PowerSupply.aspx?SLanguage=en The website recomends 650w +
and no.2 http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/amdkmdap-display-driver-stopped-responding-but-has/76992972-8ccd-4d91-b928-ddba173e69bb this thread says it could be that there isnt enough wattage going to the graphics card.
Update: while posting this I've realised it could be to do with my dodgy ram module, if you read down on the last link i posted.
Don't trust that website. Your GPU is getting way more than enough wattage with a 500W PSU. You probably don't exceed 370W under 100% load both CPU and GPU.
There is a registry hack for the drivers. Windows has a thing called TDR, it means Timeout Detection and Recovery. So it is basically a windows problem
http://ae3dtools.com/gpu_timeout/ this should work. There is a video included
I would Like to try this but i cant. The youtube video is half green and soon after i start it the display driver crashes.
could there maybe be something wrong with the GPU it self? did you do a clean windows install on your new build?
I did do a clean windows install. And im thinking the gpu might be the problem.
UPDATE
I Now have a Corsair CX750m Psu.
The display driver still crashes and now it seem windows likes to restart whenever it wants.
So... Im now going to swap the ram out and re-install windows. I mean ffs cant it just work?
