80 plus只是效能認證,並非耐用度保證 |
80 plus本身是一個硬體效能的認證,
測試內容非常務實、精確, 所以能過關的在"足瓦與否"上沒有疑慮; 但80+並非耐用度的認證, 僅由於測試過程"有點"嚴苛,因此過關者也等於有"基本的"耐用度。 官網有測試白皮書 http://www.80plus.org/research.htm http://www.80plus.org/documents/Serv...eportFinal.pdf 以下是節錄部分內容: [page6:] We contacted technical representatives from power supply manufacturers and computer manufacturers. As a result of these conversations, we identified the priorities for the server power supply test protocol. These priorities are to test for: Universal input voltage – test at 115 volts and 230 volts AC Test at extremes of load range (0%, 5%,10%, 20%, 50% and 100% of nameplate rating) Test for power factor (PF) at each load point No redundant mode testing (testing done at low load conditions to simulate load sharing) Segregate data into: Redundant and non-redundant designs Multi-output voltage Single output voltage - low (below 20 volts DC) Single output voltage - high (above 20 volts DC) 測試負載從0%~100%,而這『100%』是由送測廠商定義的, 意即廠商說這型號是500w的,80plus就只測到500w,並不會側到501w以後(over clock)。 ※某些廠商說他們的PSU可提供超出標示 xxx Watts,但超出之後,效率極可能降至80%以下, 怎麼降? 不知道!。
