\"208<\/p>\n

HostDime often gets inquiries from perspective colocation<\/a> clients about what voltage power will be supplied to server racks. While 110V-120V are commonly used in the industry, HostDime has long evolved to supply 208V voltage by default. The many benefits will be outlined in this article.<\/p>\n

Most electronic hardware including computing servers come equipped with power supplies that have the ability to support 110-240V voltage input already. Take a look at the power supply on your hardware label or any home appliance. An example below:<\/p>\n

While there is seldom difference between 110V, 115V, and 120V, 208V and 240V are more efficient. Large pedestal and rack mount servers normally use 208V. Here’s why.<\/p>\n

208 Volt Power is Best for Server Racks<\/h2>\n

<\/center><\/p>\n

Efficiency:<\/strong> There’s a 1% to 3% improvement in power supply efficiency with increased voltage, which will save between $4 and $31 annually per server in electrical cost. This occurs because the more current that wires and transformers conduct in order to power hardware, the hotter the components get. That additional heat must be cooled by an AC system, furthering the amount of electricity required to support a server. The less heat produced by components, the less cooling is required, resulting in less power consumed.<\/p>\n

 
\nCapacity:<\/strong> The main difference between 120V and 208V is that 208V circuits have more power and density, therefore requiring less PDU’s needed in the rack. For example, here’s the two most common circuits at 80% total power:<\/p>\n
