Strangely enough the PSU is pretty clean, no layers of dust, no bursting 
capacitors (no spider webs :-) - postmortem on second supply shows damage 
in the same area, same coil damaged and the top blown off the one IC on the 
board (TIP221P rated for 230V+/- 15%, switches the AC input).

Tentatively plugged in another PSU, everything fires up ok and it booted up 
SuSe no trouble (see I got it back on topic ;-).

These are "Power Man FSP235-GI" PSUs, quick look on the web didn't find a 
huge rash of complaints about them.
Same power strip with circuit breaker normally runs my other computers 
(which were off at the time).  I think it really must be a fault with this 
particular model, some startup condition design flaw exacerbated by 
everything being completely discharged and cold (maybe one of the small 
electrolytic capacitors breaks down).
