flashing led and psu

[lionstorm]

Hi all,
I put my A1200 MB back to the desktop. Without accelerator card, nothing wrong. When I plug my A1260, sometimes the power led is flashing, sometimes not. Why is that ? Connectors do not look dirty.
Another question about power supply : In my tower I have 3 HDs, 2 CD-burners, 1 BlizzardPPC , 1 BvisionPPC and 1 varIO card. Is the power strong enough for everything ? What is the rule to follow ?

The winner tower has a 250W PSU AFAIK.
It is 2 separate topics :
-the flashing led on a A1200 desktop with original psu, with or without A1260 blizzard
-a question about my tower and how much the psu can cope with the list of all my things which lay inside
