I received all 8 of mine that I ordered today, I almost ordered 10. Yes I have a problem, lol... and it was only $13 shipping for all of them, to bad I had to pay the new "rediculous" tax of like 9% here in Cali. I got a large box, which looks like they were shipped to them in. The box was very beat up, even though it didn't have to go that far. (geeks isn't that far from me). They removed 2 from the box and didn't put anything in the space where they removed them so they were able to move around a bit, might be why the boxes integrity was a bit weak. But they seem to be fine, no big dents or damage yet.
The connectors DO NOT SEPARATE! Neither the 24 pin nor the 8 pin. I am sure there is a similar model that does, but these do not.
But, I don't care, these power supplies were the right price, and that is what matters. I can always drive over to monoprice since it is about 10 min away and pick up some cheap cables if I need em.
So far the quality looks good, I don't have a box to put one in yet, but I'll test them soon.
