5A should be plenty I'd think .. but I guess it also depends on the
voltage ..
A few years ago I experienced issues with an ALIX board and a high power
Ubiquiti/Atheros-based mini-PCI card .. if memory serves I think it was
an XR-2 .. in that case though the miniPCI card would sort of brown out
and that could lock up the PCI bus leading to a kernel crash or watchdog
reset. In that situation the issue was internal to the PUPS on the ALiX
board - a known limitation wrt how how much power could be supplied to
the miniPCI slot.

Hi Nix,
It's almost certainly a power issue as power draw for the lan card will not
be a static thing - ie will increase when transmitting packets vs idle.
That's an intersting theory. I also run an external nic in the PCI
slot of a Net5501-60. In my case the OS is OpenBSD 5.5 and the nic
card is an Intel dual Gigabit PCI-X unit. I also experience reboots of
this configuration under high packet flows. In my case though my
machine is in the Net5501 rack mount case with the 5.0A power supply.
I will arrange to test by swapping to a newer 5501 rack mount case and
retesting.
Thanks
