2. The trouble with using auto bulbs as loads is that they take a very high surge current when you first turn them on. It may be this surge current that is tripping the PSU.

I had to agree with you. I did another load test on the ATX Bench power supply I converted two years ago. It has +3.3V@13A, +5V@15, +12V1@20A, -12V@0.5A, +5VSB@2A, power rating is 450W. When I connected 55W light bulb, it blew 2A of fuse. After replacing it 10A fuse, I connected 55W light bulb and the light bulb turned on. Out of curiosity as soon as I connected two 55W light bulbs, the PSU stopped running.
