== Benefit ==<br />
<br />
Power from a 3-phase circuit equals voltage multiplied by current multiplied by 1.732 (the square root for 3). As a result, a 3-phase circuit provides 1.732 more power than single phase power, which in turn reduces energy costs.

== Global Power ==<br />
<br />
"Generally speaking, most modern servers are rated for 100-240V or 250V operation, much like the majority of today’s consumer electronics. The simple fact is that building a global power supply is oftentimes more cost efficient than building a narrow voltage input range power supply. There is great benefit in being able to simply match a power cord and get running."<br />

"There’s a one to three percent improvement in power supply efficiency with the increased voltage, which will save between $4 and $31 annually per server in electrical cost."<br />
