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:

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..... |
