Figure 14: Power supply label.
As you can see, according to the label this unit has two +12 V rails. However inside the power supply this product has only one +12 V rail and thus this unit is a single-rail unit. What happens is that 3R System added separated filtering circuits for the two group of wires they call +12V1 and +12V2, which is great, but what constitutes a two-rail design is the presence of two over current protection (OCP) circuits, which this power supply doesn’t have. Read our Everything You Need to Know About Power Supply Protections tutorial for more information. Now let’s see if this power supply can really deliver 450 W.
