It is a single card in a box. The "5-pack" refers to the bigger box that these are pulled from. Its an Intel labeling/sku issue - the inner boxes are not separately labelled for sale. Provantage, at least, will offer a refund if you are not satisfied but i wouldn't expect to get 5 expander cards at this price.
Yes - that is a Molex for power and yes - it does power the card and work outside of an Intel chassis. I have an idea for mounting it in a SM chassis and will post pictures if it works out well (obviously no pictures if it is a fail or looks like crap ).
