After a few recommendations I downloaded furmark Asus version to test my antique hd 7950 . I ran it once and it was fine temps never seen over 60c. Second time I ran it temps went up to around 62c around that point I seen sparks started to fly from the gpu. Lucky the motherboard survived and I had already ordered a replacement gpu few days back. I'm curious, I know 62c isn't extreme for a gpu. Could've the failure been caused by the PSU and not the gpu?
