The card is manufactured by NVIDIA. Zotac buys the cards and picks the best overclocking samples to use on this 8800 GTX OC Edition Series. Basically everything remains the same for this Edition, except for the sticker on the cooler and the BIOS.
NVIDIA states that their GPUs need a lot of power, that's why two PCI-Express power connectors are in place to not exceed the 75W maximum power draw per connector.
You need to connect both power plugs for the card to work. If you connect only one or none, a loud beep will sound from the buzzer on the card.
The back is clean, the memory chips are on the other side.
Zotac's GeForce 8800 GTX has two dual link capable DVI outputs, so you can connect up to two widescreen high-res LCDs, for example with 2560x1600 each. In case you need an analog output, two DVI connectors are included with the package.
