You need to upgrade the power supplies as well.

Hi,

We have duplicate pwr-c45-1000ac. We use 341 watts and max available is 1000. Is that not enough?

You have to run the power calculator

There's always something...

I ran the calculator, including my projected PoE cards, and it says I will use roughly 50% of my available power. But this assumes I use 1300W PS's, which I don't. I use two 1000W PS's. I can't change the calculator to figure in my low-rent power supplies, but I can extrapolate, and take a guess that I have enough. Is that bad mojo?
