Quantity of power is important, but the quality of power (stability/regulation tolerances) cannot be overlooked.
Get youself a brand-name PS (Enermax, Enlight, Vantec...) in that wattage range and you should be fine.
If your FSB 166 is O/Ced to 185, then your AGP 66 is O/Ced to 74, and your PCI 33 is O/Ced to 37MHz.
This is often as much of a limit to people's O/Cing as is their CPU, and can be a major source of system instability.
AMD Athlons @ 133 FSB should be run @ 166.
Athlons @ 166 FSB should be run @ 200.
This 'factory' O/Cing keeps proper dividers for AGP/PCI, but most often works only on CPUs with the lowest multipliers (like XP2000+ or 2500+ Barton).
Apply core voltage as req'd, don't keep trying too much past 1.75-1.8 volts (or else, bring marshmallows & weenies ;-)
Lots of info in Praetor's O/Cing forum...
