    Bottom Line: Grading of the Enermax, Antec and Silverstone Power Supplies was tough, but with stable rails and quiet operation, both the Enermax and Antec are going to come out on top.

    Introduction

    Dual 12V Rail PSU Shoot Out

    Today, we're going to take a look at three different power supplies.  The power supplies are from three different manufacturers: Enermax, Antec and Silverstone.  All three are quiet different from the next in several ways, but all three have two 12V rails.

    Here are the voltages for each of our three power supplies:

    12W
    10W
    498W
    22W
    520W

    As you can see, these are very substantial power supplies and will likely work fine for 99% of our readers.  I wouldn't hesitate using any of these power supplies with an SLI system, even though none of them are actually certified by nVidia to do so.

    First, let's take a look at the Enermax.....
