转换效率就是电源的输入功率与输出功率的比值:即电源转换效率=电源为主机提供的即时输出功率/输入电源的即时功率×100%。一般来说,PC 电源规范对转换效率有着一定的要求。最初电源转换效率仅有60%左右,在Intel 的 ATX12V 1.3电源规范中,规定电源的转换效率满载时不得小于68%,而在 ATX 12V 2.01中,对电源的转换效率提出了更高的要求——不得小于80%。因此在购买电源时,从它遵循的电源规范上大家就能大致了解其电源转换效率的高低。
Conversion efficiency is the power of the input power and output power ratio: power conversion efficiency = power for the host to provide real-time output power / input power instant power × 100%. In general, PC power specifications have certain requirements for conversion efficiency. The initial power conversion efficiency of only about 60%, Intel ATX12V 1.3 power specification, the provisions of the power conversion efficiency of not less than 68% full load, while in the ATX 12V 2.01, the power conversion efficiency put forward higher requirements - - Not less than 80%. So in the purchase of power, from its compliance with the power specifications we can generally understand the level of its power conversion efficiency.
