I tried overclocking my gpu and stress testing it to see if it was my psu and no my pc didn't crash even if i set my gpu power targer at MAX and overclocked it something like +150/+500. But thanks for the tip let me test if the gpu is inserted properly
. As far as i know my psu is big enough to run my current system the problem lies somewhere else.
It's not just a matter of the advertised wattage rating. There is so much to PSUs that it's overwhelming. You can't just say, "Well, it's rated for 500W. That's all I need to know." No. You have to know much more than that. What's the +12V wattage capacity? How good is the ripple suppression? How good is the voltage regulation? What have professional reviewers said about it? I could go on and on.
The fact that you describe it as "some 500W Cooler Master" scares me.
Perhaps the scariest thing is: there's no way to know how good or bad your PSU is without using proper PSU testing equipment. You can't say, "Well, my computer seems to be running fine, therefore my PSU is good enough." I'm afraid that's no way to judge a PSU. The problem with a crappy PSU is, you don't find out it's crappy until it's too late. You always find out the hard way.
If that thing is as bad as I think it is, and if it dies because of all this overclocking and the HUGE increase in power consumption you just created, it could easily kill your entire computer.
The same goes with extremely high-end PSUs though, except when THEY die, they usually die harmlessly (they don't kill anything). Even so, if you have a bad high-end PSU (like maybe it's defective), you can't find out. You can't tell. You don't find out until it dies or your system starts having strange instability problems that you just can't fix.
