hey guys. i have had a pc for 7- 8 years and yesterday i upgraded the graphics card to a pny geforce 1060 and the ram to 12 gig. my cpu is old (amd athlon 635 processor). the important part is that my power supply is also an old green 530 watt (7- 8 years used). will the power supply be safe for my system or should i buy a new one? i am really worried about the power safety of my pc
