Ripple Measurements

To learn how we measure ripple, please click here.

The following table includes the ripple levels we measured on the XP1200M's rails. The limits, according to the ATX specification, are 120 mV (+12V) and 50 mV (5V, 3.3V and 5VSB).

Ripple suppression is pretty good on all rails. Because the competition in this category is really tough, Gigabyte's XP1200M doesn't place higher in our comparison charts. Still, this doesn't change the fact that Enhance fares well.

Ripple Oscilloscope Screenshots

The following oscilloscope screenshots illustrate the AC ripple and noise registered on the main rails (+12V, 5V, 3.3V and 5VSB). The bigger the fluctuations on the screen, the bigger the ripple/noise. We set 0.01 V/Div (each vertical division/box equals 0.01 V) as the standard for all measurements.

    Yawn. It's loud. Might not be too loud in most people's cases where the unit is sucking cool air from underneath the computer, and where they overestimate their power requirements, but it's still way too loud. If they're going to make the fan that aggressive, they should give it a longer warranty. Give it an ol' 11 year warranty to beat the competition at least.

    The only way Gigabyte is going to sell this at whatever price is if they do some marketing. "Nvidia Gigabyte GPUs work best with Gigabyte PSU" and people will buy it.

    Enhance continoues its mediocre performance!!
    The only series i can remember, in which Enhance showed some very good results were the Thermaltake's GRAND Platinum line.
    Besides that,..... just mediocre !!

    When i saw that it used the word "xtreme" (ugh) and "gaming" together in the name of the product i knew it was going to be either overpriced or underperforming. Or both.

    Built by enhance electronics but only five years warranty !

    In the 1.2kw range... The EVGA SuperNOVA 1200 P2 is a great buy @$230 (or so), awesome specs and performance across-the-board and some of the highest customer ratings to back it's build quality.
