I have always powered the TIU for our holiday layouts with a couple z1000's. However, I am building a permanent O and STD layout, and was wondering? Can the TIU handle a total of 4 ea. Lionel 180 watt Powerhouses? 2 ea for fixed and 2 ea for variable outputs?

As Rod said, not a problem, IMO, the best possible setup available. I have one PH-180 on each fixed TIU channel right now. With 2 more PH-180s waiting for the variable channels. That is, if I ever get going on my layout expansion...

I agree.  I would note that, depending on what you run on each channel, a PH-180 can power more than one channel.  I have one powering 2 channels, each of which feeds a yard area where, usually, only one loco would be moving at a time.

I wonder why MTH didn't make a 180 watt power supply to feed the TIU? I guess they want you to buy two Z4000's? They couldn't possibly want you to buy Lionel bricks...

Inputs only.  Black to black; red to red. 

Incidentally, I recommend jumpering all output blacks [ONLY], regardless of how the inputs are fed, for other reasons (not necessary if you have one of the priginals Rev G TIUs)..

Good question?  IMO, Lionel's PH-180s would be really hard to beat for price, great breakers, value (watts per dollar), etc. 

Remember, it was hearsay that they had problems with the new mfr.  I have one of the older ones and, based on my experience, it you are running DCS, it is by far the best power source for the channel inputs.  I wouldn't have the slightest reluctance to buy a new one now, if I needed one.

My newest ones are from 2017, also after a long wait for them to be re-stocked. Looks like I lucked out on the problem batch, hopefully anyway.  But, I would not hesitate to buy a new PH-180, if I ever happen to need another one. I would imagine Lionel would take care of any problems with a new one, as long as the problems were discovered during the warranty period.
