i think i might be stepping my bounds after thinking about how much draw my system is putting on my m1-atx.

via en 1200eg
2x 2.5" ide-hdd
gps reciever*
bluetooth usb
wifi usb
tv usb
lilli in dash*
LED touchpanel switch
usb keyboard

i was thinking 90watts might not be enough for my m1.
can anyone shed some light on this or point me on the right direction?
