Burned Connectors in PCs
We have a rackmount PC with a 400 Watt power supply.
The power consumption of all our cards is quite high, about 284 Watts,
still less then 75% of the rating though. The power supply is rated
for
30-50A for the +5V
20-11A for the +12V
Shared
between the 2
We are drawing 36A of +5 and 8A on the +12
The problem is that, after time (6 months - 1 year), the units will fail
and we noticed that the connectors which mate with the backplane are
actually fused(melted) to the backplane. In line with the +5 V
wires (red wires), the connector is actually black and in many cases the
connector is arc welded to the backplane.
Ideas.
