I ran F@H for about 30hours straight with GPU at 100 percent no problem. But now i run it, and after about 15minutes my psu makes a small crackling type sound. I did only buy this PSU untill i had the spare money to spend alot more on a better one.. but ive only had it, what, one month ? and it's allready sounding like its breaking if my GPU draws to much power for too long..
I'm not sure how serious the problem is, that's the problem. I don't know whether its anything to worry about or whether i should be turning my PC off as soon as i hear it. It is definitely when i run F@H. As soon as i stop it, my PSU stops making the sound like 1 second later.
