GPU Upgrade

[333robbie333]

Hi

I recently upgraded to a GTX 780ti from a GTX 670. Now in games I get an error message saying the following: "directx function getdeviceremovedreason failed with dxgi_error_device_hung". I have searched a lot of fixes online, but none are working.
Here are my basic PC specs:
I5-4460
Gigabyte GTX 780ti (Model no: GV-N78TOC-3GD).
EVGA 500W PSU

Originally everyone said that the card is overheating, so I should lower my clock speeds to what a standard 780ti would have been out of the box. (I have a factory overclocked card).
That didn't work, so I contacted the guy who sold it to me and he said that my Power Supply Wattage is insufficient.
I checked my PSU requirements on Seasonic's website and the results are as follow:
Load wattage: 493W
Recommended PSU wattage: 543W

So I am kindly asking you professionals out there for advice. Should I buy a better PSU (Because I can't really afford one at the moment). Or is there another possible cause for the issue?

Thanks in advance!

Hi It's been my experience that such errors may be due to low power, IMHO. Anyone correct me on this if I'm wrong. I would suggest a PSU of at least 600W, although it doesn't hurt to have a little extra. I would recommend a Thermaltake ToughPower 80+ Gold 750W PSU (around $90) but that depends case space.

I know I am late to this thread but I agree with Silverbeard. A PSU that provides a little more wattage is the way to go.

Hi everyone!

Thanks for the opinions, I bought a 735W PSU and it seems the problem is now fixed.

Thank you all so much!

PS. Can a mod please mark this thread as solved?
