Tank too big for compressor??

I just ordered a 12 gallon 8 port tank from suicide doors. I also ordered a viair 450 compressor. Its supposed to run at a 100% duty. Someone told me this compressor wont be big enough to fill the tank by itself that i need another compressor.. Anybody know anything. I got the big tank b/c i didnt want to be like all my friends and run out of air and have to wait for the tank to fill back up so i figured i would just get a big a$$ tank..
