What will happen if I draw too many amps from a modern (decent quality) PC PSU? Will it shut down gracefully, or will it do something worse? I destroyed more than a few of those conventional AC adapters/wallwarts when I was a kid by doing this! But I would like to think that improvements have been made.

    fkn limits, i forgot... forget it - you're fine. Just don't make any internal hardware changes while the machine is on - the worst that can happen is your PSU won't kick out 1.21 gigawatts to go back in time to let you know that daisy-chaining un-fused sockets to anything is a bad idea.

    Also that PSU's have always worked this way (except now I think they have inrush to charge @ 60a / 240v).

    I'm talking about drawing too much power inside the computer. I've seen people intentionally short out a PSU, and it just shut off gracefully without damage. (impressive). So I hope a modern one would shut down if the load exceeds the max output.
