FORTRON FSP145-50NI B rev 4 PSU repair

This source has been on a pc was almost completely fried. At first glance, with his death did not want to go alone, she took the motherboard, memory, HDD and DVD-RW.
Vain hope to think that it can be repaired. I tried to power up, but no sign of life, my tester indicated only 5V VSB.
PSU waited a while, until I caught something on this forum - extremely helpful to me.
Today, after I have worked at Delta psu and concluded that I must be more careful, I said to watch it, little. And I found two bulging capacitors 1500uF/16V, which I have replaced them. But power does not turn on...
I keep thinking what to be, and I try to re-solder better the YEC capacitor 47uF/35V blue, not before measuring on ESR meter, just out of curiosity. Surprise: the capacitor has 27pF! The same situation with another identical capacitor.
Hardly I find a PCI modem with two identical capacitors - SAMWHA.
After replacement PSU power on , but with only 11.4V on 12V rail...
So, I can enjoy that I never lost this day. And I understand better what it means "recapping", thanks to @momaka, @Behemots, @Per Hansson, and others.

I think it is old group regulated platform, try loading the +5 V rail a bit, the voltage should go up quickly.
