My daisy chain brick is rated at 2A. Checking on The Power List for my pedals or equivalents, I can see the Barber Direct Drive was measured at 11mA. Assume my clone is hungrier, so say 20mA. JHS Little Black Buffer 19mA. TS-9 7.5mA. MXR phase 45 1mA. Hotone Xtomp mini 250mA max. Digitech Trio ~450mA. Ammoon Looper 140mA.

There's a trend there. The analog pedals are very low power. I could in theory run almost 200 of them at a time off my 2A power supply. I typically have just 2 to 5 on at any time. The digital pedals tend to be an order of magnitude hungrier. But they are also noisier so I run most of them off a separate power brick anyway - except for the looper. It doesn't add any power noise so I run it off the daisy chain.

Based on this, I just ordered a 6 plug extension to my daisy chain.

I do get small amounts of noise when running through the board with all pedals off, but this is probably mostly thermal noise (Johnson-Nyquist noise) that is generated simply by running power through any circuit. The noise gate in my amp handles this nicely. The noise introduced by running my Trio on the daisy chain is much louder and more annoying.
