PSU concerns are why I went with an Antec 550W supply as opposed to
some 300-400W noname brand. Since my rackmount case does not have room
for a redundant supply, I suspect this is the best I can do. As you
say, PSU problems are relatively rare.

That said, anyone know how I can dynamically measure
the actual wattage used by my system, beyond just
adding up each individual component's wattage?

http://www.ahernstore.com/p4400.html about $30. I've got one.

Thats measuring the power INTO the power supply, not what its supplying
so isnt very useful for checking how close you are getting to the PSU rating.
