I've just done a bit of Googling and can't really find anything much about them, which is generally a really bad sign. He is taking a risk with his hardware.
How many amps does it provide at 12V? You can calculate the wattage by multiplying the amperage on the 12V rails by 12. Any decent design will provide almost all (like 90%+) of its rated wattage on the 12V rail(s). If he's running well, well under the rated amps at 12V (as in the actual rail rating, not the generic "650W" rubbish that these units are often sold with), then the risk is lower - but still there. If he's pushing over 50%, or even anywhere near approaching the rating on that PSU then I'd say he's basically playing Russian Roulette with his PC.
