It definitely has its own power source so it doesn't take any power
from the USB port. I've attached it 'live' to the Iyonix on dozens of
occasions in the past without any issues whatsover over the last six
or more years. While it always single tasks the Iyo for up to 100
seconds (not so long since the USB improvements from ROOL), this time
it froze the pointer and I couldn't Alt-Break or Ctl-Break out of it.
I've never experienced pyjama symptoms with either the original or the
later FX5200 graphics card. I leave it running 24/7 with only rare
reboots. It went from working to frozen to restart - dead.
