The Pro-Peak supplies don't burn up easily, I work at a model shop where we sell dozens of Pro-Peak power supplies, and latterly, the LogicRC PSs, and we've only had one back, which didn't work out of the box.
If you've got 2 power supplies then yes. If you really need that much power, be prepared to spend the money. Surely you don't need all that lot on at the same time, is it all necessary? Why do you need two chargers on at the same time? If you really do need all this stuff, try one of
these. 40A at whatever voltage you want. It doesn't come cheap though.
It does depend on what cells you are charging though, at what rate, and what the power consumption of the discharge tray and fan is.
