The system I'm putting this in has a 300w power supply. I have no idea if it's "good" or not, the brand on it is "Microstar". As for amps, it has different ratings depending on the voltage. Here's the table on the side of it, which doesn't make a lot of sense to me:

Volts	+3.3v	+5v	+12v	12v
Amps Peak Amps	16A 18A	25A 27A	14A 16A	0.5A 0.5A

If I decide to test the 5970 using this power supply, how can I tell if it's not supplying enough power? Will the PS and/or GPU get hotter than normal? Can I risk damaging the GPU by using this power supply?

WHAT ?
Your OLD 300w PSU can merely provide 160w of 12v (if lucky).

Very few 300W PSU are good, in the sense that they allow 300w on the 12v. Go for 400w and 500w if you want effciency.

Thanks for the reply. I will buy a good 500+w PSU to run the card.

Is it problematic to plug it in with this power supply just to give it a test run? I'm anxious to give it a try, even if I have to clock it down or throttle it due to the poor PSU (until I can get a better one).
