Summary: Board was exactly what I expected, plugged into computer and hooked up device with no problems. Came with an internal power cord with no directions on how to use. Printed diagram directions were nice, however the directions skip step 5. Printed booklet directions nice, except didn't go into specifics of why you would want to use or not use the internal power cord. Luckily I knew how to install, might confuse those with lesser computer experience.
