The max your card will pull on the 12V rail is 225 watts since it has two 6-pin PCI-E power connectors. That is just under 19A. Your PSU should be fine.

GPUs, under load, can see temps anywhere up to 90C. As long as your temps are below that, generally, you are fine. It IS a little different than temps you want to see on a CPU.
