Myth 3: A Single Rail Power Supply Is As Safe As Multi Rail Power Supply!


Single-rail power supplies do not come with over current protection (OCP) safety functionality on their +12V rails. OCP limits the amount of current that can pass through the PSU's rails (and into your PC) when it exceeds a threshold called the OCP set point. OCP is necessary because if you experience a short-circuit in your system (which is unfortunately possible, even with modern equipment and building techniques), OCP will cause the power supply to shut off, preventing excessive levels of current from flowing into your system and damaging the hardware attached to it.

A single-rail power supply cannot offer this safety feature due to high current flowing through only one rail. This means that in the event of a short-circuit or other hardware failure, up to 100A (100A x 12V = 1,000 watts!) of current flows unhindered into the system, damaging everything in its path. If the user is unlucky enough and happens to be acting as grounding at that exact moment, this could be even life-threatening. Are you sure you want to risk your safety installing an unsafe power supply like this?

At Antec, we deliver only high-quality power supplies and always make sure our customers are safe and can enjoy the hardware components they've purchased. That's why every power supply we offer comes with the OCP safety function standard.
