【導(dǎo)讀】在服務(wù)器各個(gè)部件中，電源負(fù)責(zé)各配件能量的供給，擔(dān)當(dāng)著非常重要的角色，其重要性不言而喻。在我們平時(shí)DIY臺(tái)式機(jī)時(shí)，很多老鳥都非常重視電源的選擇。在服務(wù)器領(lǐng)域，電源可謂是重中之重。
在服務(wù)器電源方面，主要是SSI規(guī)范。SSI（Server System Infrastructure）規(guī)范是Intel聯(lián)合一些主要的IA架構(gòu)服務(wù)器生產(chǎn)商推出的新型服務(wù)器電源規(guī)范。SSI規(guī)范的推出是為了規(guī)范服務(wù)器電源技術(shù)，降低開發(fā)成本，延長(zhǎng)服務(wù)器的使用壽命而制定的，主要包括服務(wù)器電源規(guī)格、背板系統(tǒng)規(guī)格、服務(wù)器機(jī)箱系統(tǒng)規(guī)格和散熱系統(tǒng)規(guī)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:
