请问SATA硬碟的电源线
新的POWER的SATA电源线有一条是提供 +3V
但是大4P转SATA电源线没有 +3V
这样使用上会有问题吗?
以现在出厂的SATA-II硬碟
有+3V供应会比较好吗?

不用怕接吧~~~~~~

Adapters exist which can convert a 4-pin Molex connector to a SATA power connector. However, because the 4-pin Molex connectors do not provide 3.3 V power, these adapters provide only 5 V and 12 V power and leave the 3.3 V lines unconnected. This precludes the use of such adapters with drives that require 3.3 V power. Understanding this, drive manufacturers have largely left the 3.3 V power lines unused.
