外接电源USBHUB导致电脑无法开机？

NEO1201

航嘉冷静王至尊版（400W)开机没反映，换长城的可以开机，拔掉一个外接电源的USBHUB的电源线后正常启动了，难道外接电源的hub的问题？（那个杂牌的hub插上后，电脑关机后机箱上的电源灯和硬盘灯还亮着)，为啥用一个长城350P4的没问题？

觉得这个电源应该不会有问题

1. try 航嘉冷静王至尊版（400W) at other computers to make sure it's working
2. check all connection

probably it's power problem. although your USB hub has external power supply, the usb port is still providing power to the hub as well.

also, make sure not enable usb bootup option in the bios
