All these Caps being damaged messages reminds to let you guys know that you can drastically reduce the problem by actually buying high end Power Supplies. If you spent $50.00 or less on a power supply, well may I say you get what you paid for.
While I agree with you that a good PS is critical, it isn't a panacea when it comes to puffed caps. I had a motherboard in last week with eight bad caps (five by the CPU and three by the AGP slot.) I replaced them, and the three by the AGP slot puffed again within 24 hours. So I replaced them again and used an Enermax 350W PS to test for the next 24 hours. The caps puffed again. So I replaced them again with caps that were phyically bigger and these held. So it may be the caps or it may be another component puffing them, but it isn't always the PS.
The original caps I used were Nichicon UVZ0J332MPD (6.3V 3300uf) and the final ones I used were Nichicon UPW0J332MHH (6.3V 3300uf) - I have been assured by Mouser that they are "the same" when it comes to use on motherboards, but possibly there is some quality difference between the two.
I also had a machine in last week with 13 bad caps, and an el cheapo PS that was whining like a two year old in a candy store - I think the bad caps on the motherboard were directly due to the PS in that case.
