American Wire Gauge (AWG) is a standard for the width of electrical wire used predominately in North America. The standard specifies the width of the diameter of the wire, ranging from 0000 to 40. The diameter decreases as the wire gauge number get larger.
It is an important factor to evaluate when purchasing a power supply unit because the thicker the cable used the higher the temperature it can endure without problems.
In most cases, current noise is not a huge factor during normal use. This is because it’s usually drowned out by other components and fans spinning. But during idle mode when other components are off, current noise can be noticeable and annoying. This is a really odd situation because it means the power supply is causing a problem that doesn’t really effect normal operation. This problem could be easily remedied by simply shutting down your computer when it’s not in use, but for many that isn’t an acceptable option.
Currently, manufacturers can only try to reduce current noise by way of three main methods:
A. Dip the transformer into the varnish paint longer to glue every microscopic crack to reduce the switching sound when currents pass through it.
B. There are three main electrical pillars inside a transformer and usually the middle one is shorter. The middle of the three main pillars inside a transformer is usually shorter that the other two. Engineers often use glue to fill this gap which does have a noticeable effect in current noise reduction.
C. Adjust the flow of currents by altering primary and secondary copper wire twining.
Brands can demand these processes from manufacturers all they want but ultimately it comes down to the employees in the factory taking the time to do this. While all three methods do have a positive effect on noise reduction, none of them are radical solutions that completely solve the noise problem and thus are often ignored to cut costs and reduce production times.
