For a stock build with no overclocking, how important is PSU efficiency? The estimated wattage on my build list is 281W. I selected a 550W bronze rated PSU to shave costs. Since it's providing more wattage than I need, it seems like the 5-10% efficiency increase a more expensive gold rated unit would provide shouldn't matter, but I'm not sure. Thanks in advance!

If you aren't in a very small case where heat is an issue, the answer is probably "not much". Less efficient PSU's will run a little bit hotter and use a little bit more electricity. The additional heat might degrade the internal parts a little sooner so you're likely to see shorter warranties. None of these effects are large, for instance the electricity savings is going to be on the order of a few dollars per year. You might get a bit more fan noise out of a budget Bronze rated PSU, but even that's not a given.
