Quick answer, No.
If i were to buy the 150w Opus power supply, would I need an ITPS? Seemed liked the opus covered all the features the ITPS covered... am I missing something?

It does, see why the Opus costs so much? Now go order one already.
Mine needs to be updated.
Some people use the ITPS is trigger a relay to kill the standby power in the 150 watt model. The 90 watt model doens't have this issue becuase you can kill the standby power with a jumper setting.
