It could be the case but We can't tell you until you give us the specifics on you PSU first.

could be a driver issue, grab driver fusion and the latest nvidia drivers.

uninstall current driver and dont restart.
run driver fusion nvidia driver cleaner.
install latest nvidia driver as custom and only install display and hdmi driver.

see if this helps first

did you use my method of cleaning the drivers before installing new ones, it is completely different to just uninstalling them.

if another psu or pcie power connector does not change it then the card is most likely faulty.

from what i have read and experience with friends the 650 series of cards and the ti models are not greatly reliable.

could be that your psu can no longer supply the needed power and you need a new psu, were your other cards that you RMA doing the same thing?

They tested my card ...it was working fine ..........but is it normal for voltage to go down to 1.062 from 1.075 while gaming

no the card should now clock down and undervolt itself unless it is overheating which you said it is not.

i am thinking it is most likely your psu.
