Low temperatures do not bother electronic components.

Not true. I've seen more than a few switch mode power supplies that would
not start at temperatures below 0 Celsius.

Quite possibly a marginal capacitor before the cold weather affected
it.
Just a problem waiting for the right conditions.

Nope. Brand new power supplies from different manufacturers. Not just one,
but all of them. You are correct it stating that it's most likely due to
the capacitors, though. As temperatures get lower, ESR increases while
capacity decreases.
