Servers built with many CPUs and internal SCSI drives will require paying more attention to the voltage supplies.
: ICP America is a provider of computer power supplies that provide a wide range of wattage options. AC power supplies and DC power supplies and converters are also available through reputable vendors like Advanced Power Solutions.
Choose industry standards for power supplies
Advancements in computer processors, the PCI Express bus and graphics cards mean that more power is required to operate them. The ATX12V standard was developed to accommodate this need.
Intel is a leader in computer power supplies offering solutions for low consumption and high consumption. PC Power and Cooling also manufacturers a line of high wattage ATX12V computer power supplies as does Antec.
Meet high current, frequency and voltage needs for power supplies
Industrial uses of power supplies-like that of the telecommunications field, military and medical industry-will require applications to meet high current, frequency and voltage.
Powerware offers a line of high performance power supplies covering such industries as industrial, medical and telecommunications. Computer Power Supply offers high voltage products, and Magnavolt Technologies offer high frequency AC power supplies. Glassman High Voltage is a leading supplier of high voltage DC power supplies.
Locate reputable distributors of power supplies
Do your homework. Compare brands and prices at various distributors of business and computer power supplies. Buying used power supplies can also be a smart option.
