Well basically you just run furmark and prime95 at the same time. That's about as extreme as power draw can get in a PC. As most PSU's don't have have a heat sensor so the old "put your hand on it" technique is used to gestimate the temp. Its a bit hard to explain how warm is OK but basically it should be cooler then a coffee cup if that makes sense. Also PSU's have a auto shut down in case of overload/heat so if the comp just turns of during testing and wont turn back on for a couple of minutes you know you pushed PSU to hard and need to either improve its cooling or ease up on the overclocks (running stock should not be an issue at all assuming you have some kind of ventilation going on in the case).

Ok thanks! Should a cpu overclock really take that much more power?

A 3770k will use ~80 watts extra at most when overclocked.
