Now if we look at the results provided by the P-Tuner software, we see a few discrepancies. If we look at all but the +12V3, we see that the amperages and voltages are a little off. This I sort of expected. I wouldn't expect a tiny IC inside a power supply to be as accurate as test equipment worth thousands of dollars. Furthermore, voltages are bound to be higher because they are being measured at the source and not at the load and the resistance of the wire is not taken into account. But the numbers are close enough for end users. If we have a look at +12V3 during test 1 through 3, we find that it's drastically off. So off that it actually has an effect on the total wattage of the power supply and makes the power supply look significantly less efficient than it actually is. By test 4, +12V3 starts to catch up to what could be considered realistic numbers, and I was starting to think that there was a connection problem that had "fixed itself" and shouldn't rear it's head again. But, as you'll see during the hot box tests, the problem seems to be fairly consistent.
