Re: Can a PSU damage the motherboard capacitors?
The boards I'm making reference to are 2001-2002 vintage, IE, the southbridge doesn't run warm enough to need a heatsink so they didn't give it one. Also, I was wrong about the Socket 8/387 CPUs using the +3.3V rail, they actually are powered from +5V which onboard voltage regulators step down to +3.3V (a practice that came from older CPUs that were from the AT PSU era, before +3.3V was implemented into the output voltages). Some AGP slots were universally compatible with every version of AGP up until that timeframe, I believe particularly on the boards around the Socket 370 era (1999-2000).
Depends on the age of the SB. If the SB is old enough to work with 3.3V, it probably is powered directly from the PSU's 3.3V rail. Haven't looked at much else on them, though.
