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.
How much time did this take you in total? It seem to me that the problem
is cheap, cheap, cheap all the way around.
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.
I guess there must be good money to be made in fixing cheap parts....but
it seems like there should be some decent mobo upgrades that would end
up costing about as much to the end customer.
