I've been looking for a high power Mains to USB adaptor (something around the 1200mA-2000mA range) so its got enough juice to sub a USB hub too.
Also thoughts that went past- Modified ATX (or other format, just happen to have an ATX one lying around) PSU, giving 5V needed for the RPi, along with 3.3V, 12V, -12V etc that you might need for projects, and also rather handily, external hard drives (mine is 12V) thus cutting down on extra power supplies and more losses.
Current plan I'm wanting to go with- 5V USB supply, USB cable from PSU to power input on USB hub, short USB to RPi from hub for RPi Power and short USB to Hub from RPi so I get more USB ports.
Another question is: whichis the maximumthatcan withstandRPI? For500mAor 700mAaretothe board andverylow powerdeviceslikependrives. Or is itcapable of providing500mAtoan external hard drive? In that casewould have tosuministre morepower to the board.
On the other hand, the two USBportsare mounted onbringinghub, so 500mAporttheoristsare divided betweenthe two. I thinkthat perhaps themodelA,once itwill have256MB ofRAM,is betteroption as itis veryprobableneed to usea USB-HUB powered by external power adaptor.
@ lennart: Careful. Mini USB and Micro USB are NOT the same connector types. The Rpi is meant to be powered with a standard MICRO USB cellphone charger cable.
