I´ve found a Workaround, but it´s not classified by Intel. If you do that, you do it your own risk until Intel gives a offical OK:
I´m using BIOS 0344. If you not, then install the F7-Update from a USB stick like descripted at the Intel support page. Only you have to extract the zip file on a FAT formatted stick without a boot sektor. It´s the best method to update the BIOS on Intel Desktop Boards. I´ve a lot of negative experience with the express updater behind me. Nothing is overclocked at my system and I using the automatic mode for my 4 x 4 GB of 2400 MHz Kingston RAM from the Intel compatibility list of tested memory.
It´s to easy to belive - only deactivate the USB device for the Corsair dongle into the device manager. I´m using Windows 8 Pro with Media Center x64 on a Intel 520 SSD. At the BIOS enable the C6/C7 states at the submenue of the custom settings of your processor power administration. In addition I have enabled the S4/S5 states and the pci-e native mode to saving more power. I don´t know it´s necassary or not, but it do nothing negative game experience with BF3 and my EVGA GTX 780 SC. I use the discrete graphics adapter together with the Lucid Virtu MVP 2.0 60 day test version until Intel will release a offical vendor version. Then I´ve disabled the power supervisior shutdown. Attention: Perhaps your system is no more safed by this feature. Don´t forget to clear the event log of the BIOS and then save and exit (F10).
There will no more catastrophic power event. Also at a cold start. And I´m still wondering about the Corsair Link2 software. You can start the utility manually (may be automaticaly too) and you will see the actually data of your system. It nothing matters because the dongle is deactivated.
