【導讀】在服務器各個部件中，電源負責各配件能量的供給，擔當著非常重要的角色，其重要性不言而喻。在我們平時DIY臺式機時，很多老鳥都非常重視電源的選擇。在服務器領域，電源可謂是重中之重。
在服務器電源方面，主要是SSI規范。SSI（Server System Infrastructure）規范是Intel聯合一些主要的IA架構服務器生產商推出的新型服務器電源規范。SSI規范的推出是為了規范服務器電源技術，降低開發成本，延長服務器的使用壽命而制定的，主要包括服務器電源規格、背板系統規格、服務器機箱系統規格和散熱系統規格。

WTX
WTX is a new Intel?board-set and system? form factor developed for the mid-range
workstation market segment. This specification defines the board-set volume, interface
between the board-set and chassis, and required chassis and power supply features. The
specification also provides design suggestions for thermal management and
electromagnetic interference and containment. WTX power supplies come in three wattage
levels - 460-watts, 610-watts and 800-watts. Several manufacturers of Intel?architecture
based workstations collaborated to define the WTX form factor and to incorporate flexibility
to accommodate the best designs for current and future mid-range workstations. The WTX
specification is provided for widespread use in many types of systems. The specification
and other information on WTX are available through the following web site:
