In the process of building new system. Don't have motherboard yet. I plugged in my new Seasonic S12 380w and wanted to test it out as well as the 120mm fans. I connected the molex power connectors to the CD-ROM, the 120mm fan and the Sata HD. I shorted the green and black and it powered up. All except for my Sata hard drive. I could not hear it spin up. I tried the legacy power connector and then the Sata power connector (not at the same time of course). I hope that doesn't mean I have a problem. I guess I'll know for sure if there is a problem when I get my mobo but wanted to get some insight here in the mean time.
