I think Tony's spotted a very strong clue, here. Kinda
makes me suspect that the voltage measurement is going
wrong for some reason. Could there be some non-DC
component that's making the meter read wrongly?

The
electrolytics are Mallory CGS 2900MFD 250VDC. The one on the - side
And there's another clue. Those capacitors are rated for 250V, and yet
you're seeing 280V across them. While they'd probably stand that for a
short time, not computer power supply would be designed to work like
that. So either there's a fault, or you're not measuring the voltage you
think you're measuring.
