Hmm. We need more information about the PSU. The comments above apply only if it is a quality PSU which I doubt it is.
If you could crack open the case and either read the amperage and rails off to us or simply take a picture of the label we could tell you if you can run it or not. Brand name is also important.
The funny thing is there isn't a label. Which is why I'm unsure of the actual output it can generate. I looked everywhere, even peaked inside the psu itself. Nothing. I can tell you that the part number is 0f217j. That is what's on the small sticker on the side of the psu and that's it.
