New PSU to solve GPU problems

post #1 of 10
Thread Starter 
Hi all,

I'm running a 430w Corsair 'builders series' PSU, but my 6870 GPU behaving really strangely. Sometimes it will increase clocks, other times it won't and often crashes.

Do you think a higher rated PSU will solve the problem, and if so, any recommendations?

Cheers.

I'm not sure that your psu is the problem, but it certainly is more than enough power for your build.

Don't think it's your PSU. What drivers are you on?

Thanks for the quick replies. I'm using the latest drivers from AMD...

The full, grisly story can be found here.

I think the card might be knackered.

Your card must have a serial #, unless someone has removed it..

I think that's exactly what's happened - it looks like the serial has been erased on the box. I thought I'd caused the problem by installing the wrong drivers etc and with work and everything else, it took me a while to find the problem, meaning it's outside of the 90 day complaint thing from ebay / paypal.

Problem mostly solved. I upgraded my PSU from 430w to 600w. Hope that helps anyone else with similar problems!

The CX 430 is enough power for your specs, that it couldn't do it doesn't mean that you needed more wattage, just that the CX was faulty

I hope not - I sold it on Amazon Marketplace last week! They've not contacted me about it being faulty. I hope it isn't!

I exchanged the PSU when I heard the fans decrease suddenly when loading a GPU intensive program and guessed that it was trying to draw more than was available.

These guys used a Radeon 6950 in thier test system
http://www.legitreviews.com/article/1766/15/
226 watts from the wall while gaming with the FX4100

TPU shows the 6870 and 6950 being very similar in power consumption
http://www.techpowerup.com/reviews/HIS/Radeon_HD_6950/27.html

I have an oc'd Q9650 with a GTX260c216 ( see the TPU link for it's power draw ) on an Antec NE400c, and have no problems maxing them out with OCCT psu test

Can't understand the CX430 not being enough for your specs
