Can bad caps on a motherboard kill a PSU?

In a recent thread here ("") I was testing out a new tool to quickly diagnose whether a PCs issues were PSU related. Turns out the power supply tester and the PSU were defective (behold the power and of the multimeter). Anyway, The Antec TruePower 380 PSU is only about 26 months old and seems a tad young to be dying seeing as my other Antec TruePower 380 is over four years old and running perfectly. The motherboard in the system with the bad PSU is one of several Gigabyte boards I've owned that have been affected by the bad capacitor issue. I'm wondering if the buldging caps on the GA-7VTXE+ board could have caused the early demise of the 5V rail on the PSU?
PSU readings on the 20 pin ATX connector:
Pins 1, 2, and 11 (3.3V): 3.28V (good)
Pins 4, 6, 19, and 20 (5V): 4.68V (bad)
Pin 9 (5VSB): 5.05V steady (good)
Pin 10 (12V): 11.66V (good)
Pin 12 (-12V): -12.58V (good)
