Replacing motherboard capacitors
Just tried powering up an old (386) PC, and was greeted with an acrid
smell and a puff of smoke; one of the motherboard capacitors had blown. I'd like to try replacing it, but my main concern is: what rating should I buy as a replacement? The surviving originals are all marked "10+ 16J". -- John Elliott |

As they smoked I'd assume they're across the supply, ie filter caps, so as long as they physically fit, electrolytics are a reasonable choice for replacement. Tantalum caps have very high failure rates, and worse still they often fail short circuit. I never use them unless I have to. Dave |
