That's a hard question to answer without knowing what you're powering!
The CPU board, especially if it's a very recent one, should use far
less than 150 watts (60 watts would be on the high side for a lot of
new boards).  But you've undoubtedly got memory, disk drives, and
a number of peripherals plugged in too.  I have some 10 mb hard
drives that use more current than much more recent 1.2 gb drives.
You need to look at the specs for all the devices in your machine,
add up the worst case current draw, and take it from there.
