God damn, this thing is huge. If my knowledge of naval classification is correct, it is a Nimitz-class videocard.
Unfortunately, there was a small oversight on my part, namely, that I don't have any PCIe connectors on my power supply and I neglected to order an adapter. I already installed the card, and I don't want to remove it, since it was such a pain in the ass getting it in.
Does anyone know if I can try booting without the additional power connectors inserted, or is that going to bite me in the ass? This would only be a temporary thing, until stores open tomorrow.
