Get a real power supply. What you have is a "PSU shaped object". That's a dumpster fire waiting to happen, and it will, given enough time. I understand that money is a problem right now but that does not change the fact that you have a piece of crap power supply and that piece of crap power supplies are generally the problem in about 90% of cases like yours. In any case, there is no way to even begin trying to determine what else might be at fault until you have a power supply that is trustworthy because it is of AT LEAST acceptable quality (And preferably of decent to good quality).
What you have isn't. Even the specifications decal on that unit says "this is a POS" since it has only 35 amps on the +12v rail making it actually only a 420w unit despite being advertised as a 500w model, and almost unilaterally across the industry, power supplies that are advertised to be a certain capacity but based on the specifications decal are significantly below the advertised capacity are generally very terrible quality regardless of whether in the end the actual listed capacity would still put it above the recommendation for the graphics card in use. The bottom line here is that the most important component in your system is the one you spend the least amount of money on and now you are seeing what happens when you do that.
I realize also that you might be in a region where good power supplies are hard to come by but I'll tell you the same thing I tell everybody else, that does not matter. Your hardware does not CARE where you live or whether you have money or not. It still requires the same things to work properly as it does in any other region and for any other person. When your hardware does not have clean, stable power in sufficient quantity, it doesn't work. Period.
So if I were you I'd figure out a way to get a GOOD, or at least halfway decent power supply, unlike what you have now.
These will help you to avoid getting another piece of garbage.
Below you will find MY standard list of recommended power supplies and beyond that this thread is intended as a landing place for questions or discussions regarding specific units, platforms or related PSU tech, all of which are all welcome to be discussed here. If it's related to power supplies...
