Since this power supply features a single rail design, there is not much to talk about here. It was interesting to notice that inside the power supply the +12 V wires were grouped into four rails, which allows the manufacturer to create a product with four rails by installing individual over current protections (OCP) on them. The difference between a single rail design and a multiple rail one is the number of over current protections. On the single rail design only one circuit is used monitoring all +12 V wires. On multiple rail design the power supply has individual over current protection circuits for each group of +12 V wires (the so-called “rails”).

Now let’s see if this power supply can really deliver 700 W.
