Re: My 5 year old PSU okay for a video card upgrade?
You will be just fine...
You have not be running the psu anywhere near the max power draw and that is was causes the psu to run hot and that in turn is what destroys the caps.
You will be just fine.
Sometime in the next 5 years the psu probably will fail but by then you will be on to a whole new machine anyway.
If you really are worried about the psu go ahead and get a new one for about $100 in the same or similar size.
Hardocp has a variety of good PSU reviews where they really stress a psu. Go with any of the models that score silver or better. Corsair has been making some nice psu's for a while now.
