A most valid point, but then one wonders why the board has room for two; in this application the limiting issue is cooling and not current and I used a matched pair.

However, the rectifiers look like 1A units which would explain why they failed.

In my repairs I have not encountered bridge rectifiers in that configuration. Maybe in the future I will.

There is also a 430W, 500W and 600W version of this supply, probably all using the same board.

The first time I heard about two bridge rectifiers fitting in parallel! News to me! Thanks for sharing!

all the best...

Although I wouldn't risk burning a blu-ray or a dvd on computer with a maybe still questionable 500 Watt power supply?
