So yes, I think you're close to your limit at 164 watts from the wall! The PSU is about 90% efficient, which means 150 watts on the DC side will be ~110% of that on the AC side (110% of 150 watts = 165 watts). Close enough. If you try to draw more power than the PSU can deliver, there's a chance it will shut down.

This particular PSU comes in 4 models, (12v, 19v, 24v and 48v).
