I'm racking my noggin trying to figure if I have enough juice...
T-rex Classic, specs say its 1500mA of power.
I have 9 pedals, but in my board one of those is the Bass Whammy and that pedal says 1300mA of current.

Now Ive seen pictures of folks' boards that also have a Whammy and everything run off of one brick.

If I combine all my pedals its around 2300mA.
Should I add a separate power supply for that Wammy? Obviously I'm not using them all at the same time, but, 1300 doesn't leave room when my wirelss is also using 250.

I’ve had high power consuming pedals function on the fringe. They become unpredictable. I ended up adding another supply, and no more issues.

So for me, I did the math, and use enough power to cover my needs.

So I’d say, either get one supply that covers it all, or add capacity.

Digitech says the Bass Whammy uses 265 mA @ 9 VDC.

I sure hope its only 265mA.

My box is stored somewhere in the attic, I looked at my pedal and it has the same as pictured here. Was thinking that sounds awefully high.

Mike, look at cioks dc-7 / Eventide Powermax if you decide to upgrade. I went cioks dc-10 years back. Finally upgraded to the Powermax to get enough output to support an HX Stomp (with a Y cable). It is a really good supply and has an aux USB power out to boot.

One thing you should be aware of with the T-Rex Classic is that the 9v outputs aren't individually isolated. It basically has three isolated sections: 12 volt DC, 12 volt AC and all the 9 volt DCs.

This MAY work fine of course but personally I've had severe noise issues with the Classic, especially when combining certain 9v digital pedals with 9v analog pedals. The 9v section on the T-Rex Classic really isn't much more than a glorified daisy chain splitter cable.

You won't know until you try which is why I always recommend people NOT to buy the Classic.

None of the other T-Rex power supplies could deliver the specific power outputs/ratings I needed so I went with Cioks instead. Much better IMO. But their extra optional cables are OUTRAGEOUSLY expensive and they only supply the bare minimum with their units so you may need some of those extras. And of course they use a different type of cables with a phono-style plug at one end so you can't use cheaper varieties of the standard cables that every other brand use.
