cs381 背板电源线接上后系统就不post了

银馨提供了pcie 8pin 到双6pin的线缆。把此线接到海盗船sfx-l的电源8pin口，接一个6pin到背板上，没放任何盘。不接其他线缆。 开机系统就不post。
请问这个怎么解决？ 主板是h13sae-mf。
不接就能post
1. 银馨提供pcie 8pin 到双6pin的线缆： 转换+12v到+5v
CS381 includes a PCIe 8pin to dual PCIe 6pin adapter cable for use with the included hot-swappable backplane, which has circuitry to convert +12V power down to +5V for powering hot-swappable drives and requires two PCIe 6pin connectors.This is designed to mitigate the need for choosing power supplies with large +5V capacity in order to support potentially high amount of drives that the CS381 can support.

看一眼说明书，正常硬盘背板应该是5v供电，哪怕厂商给了8pin线，也可能是那种服务器电源的5v 8pin线。

家用电源的8pin，应该是12v输出
