I want to integrate a RaspberryPi into the case of my desktop PC, that has an ATX-PSU. I want the RaspberryPi to keep running, even if the PC is shut down. It would be nice to avoid the additional cable from outside the case to supply the RaspberryPi. So, is it possible to use the +5VSB to supply the RaspberryPi and the PC in parallel? It should work supposed the PSU delivers enough power via +5VSB, right?
I thought of using something similar to this, but without PS_ON: http://www.amazon.de/Aqua-Computer-Connect-24pin-Standby-Aquaero/dp/B002BX05CM
