My Case fan not running when connect to PSU in my new case Tags: Homebuilt Cases Fan Connection Systems Last response: April 9, 2010 8:28 AM in Systems Share yingwuzhao April 8, 2010 11:25:10 PM I just got my new Lian Li case, and new PSU Seasonic X650, so I am just testing the new case. (nothing is installed inside yet) But when I connect the case fan to the PSU, the fans from the case are not running! Is the PSU dead, or did I miss something? Help please, guys!

Your PSU will not "Power" on unless it receives a single from the motherboard to kick on or it is jump started. Here is a good link describing the method on How To: Jump Start A Power Supply (PSU) / Test A Power Supply And Components. This should allow you to test your case fans. yingwuzhao April 9, 2010 1:04:37 AM Thanks a lot, man. That solves my doubts, but that technique looks scary thought. Can't find your answer ? Ask !
