See, it depends on your PSU. If it is above 550w and a 80plus certified, you are just fine to go. If u have less, u can fry your mobo and PSU can blast. So, check out the requirements of the graphics card you like on its respective site. Also, please post full specs of your PC so it can be easy to recommend what will be the best for you and what is it that is causing the problem. Mention the following things in your specs:
If it interests you, a long time ago I had a power out in my town while I was playing Battlefield 2. Long story short is that when I turned on my computer after the power out I found my 9800 GTX was fried or atleast dead and I was out of a Warranty.
My father's guess is that the power out caused a surge(spike in voltage) and that's what killed my GPU.
Makes me regret not spending more on a better PSU. Don't make my mistake and burn a $300 GPU in the process.
the PSU was quite pricey and is very silent, so not crap..
so any ideas ?
This doesnt tell us anything just because its slient doesnt mean anything..Kinda funny people trying to help u out with your problem but you wont give a answer which is why people think you have a garbage psu..Look inside the tower and let us know the name
