    that is a good gauge for figuring out what is a quality PSU. it lists all of the major ones from best to worst to not-recommended.

    unfortunately for you, you'll find that even a tier 2 or 3 power supply, and 3 is pushing the limits of quality, will range from 80 dollars and above.

    one of the cheaper ones that i believe is good enough to run most systems, based off of what i'm told and recommended, is the Corsair CMPSU 450VX. it gives a lot of power for the price, and it's very high quality. 80 dollars from newegg.com.

    anything below that price is pushing it. because when you start seeing 600watts going for 50 dollars, then you know you've found the low quality pieces of junk.

    You could get one of these PSU's if you wanted to, but as soon as you go to boot your system they'd explode. Maybe even quite literally ;)

    I can't suggest a particular model for you because it depends on what your definition of "newer stuff" is and what it is you want the PSU to power.

    The very first thing you might want to look for a PSU is the current of +12v rail. As in your case the +12v rated at 25A means it provide maximum of 300watt of +12v. While that is good enough for a "normal" system, if you want to upgrade to a more powerful VGA card and multiple hard disk, you might want to look for a better PSU.

    If you are on tight budget, that PSU would be enuff for you, but if you have extra budget, I'd say go for a better PSU.

    You will probably need at least 450W but it depends on what card you want to get.

    Enermax Liberty and Infiniti PSU's are very good and which one you should get depends on how many Amps your GPU needs, because the Infiniti gives out more Amps on the 12V.

    True, but that is the maximum load so you don't really want to break into that if possible.

    You would be looking at spending about $100 on a new PSU and probably about the same on the graphics card, possibly a bit over $100 for each, depends on what you get.
