I know a while back there was a thread about replacing computer
motherboard caps; I noticed in CompUSA the other day that they were
promoting some new motherboards with "premium quality Japanese
capacitors." It sounds like baloney, but apparently quite a few posters
here have revived dead mobos just by replacing the power supply caps.

Well, the currents in those power supplies are also quite, uhm, substatial, for teh little caps - that are close to warm stuff liek CPU and switcher as well.

One Pentium D: 1.3 volt, 130 watt thermal design power (pek is higher, average is lower) - that's 100 amps for the little caps.
