You can try, but this would be pushing it. Your second psu might as well end as this one. And when psus die, sometimes they take other things with them. Like cpu, motherboard and pretty much everything. Good psu will save you money, not take it.
It is enough, but note that vs series are not exactly an example of quality either. Get ax, hx, tx or rm series. You wouldnt even need that many watts, 550 would be more than enough, but of course, 650 cant hurt
Then, sir, your assumptions were most likely correct. I would say, try with a better power supply.
my psu is under warranty,so my ques is should i replace it with the same one cause i think the current one might be defective,as i dont plan to OC ,cause budget is a bit tight here man,i dont want spend more
on another psu
