As was common with the GeForce 7800GTX, a great deal of the power circuitry with the 7900GT is found towards the end of the PCB. However, one of the differences is the lack of a heatspreader for additional cooling of the power needs. At the end of the PCB, the 6-pin PCI Express connector can be found. The power connector is required for proper operation as a PCI Express x16 interface is not able to supply the adequate power. For those that lack a 6-pin PCI-E connector on their power supply, EVGA does include an adapter that takes use of two molex connections. The 7900GT green PCB is not quite as long as the 7800GTX, and is compliant with ICES-003 Class B specifications. Moving towards the opposite end of the motherboard, at the top is NVIDIA's infamous SLI connector. The NVIDIA GeForce 7900GT is fully compatible with NVIDIA's Scalable Link Interface; however, the SLI bridge is still required in order to run in this multi-GPU mode. At the end of the graphics cards are dual dual-link DVI connectors and the connection for HDTV output or S-Video. The dual dual-link TMDS DVI-I connectors do support two Dell 30" WS or Apple 30" Cinema displays. No video input methods are supported by the GT variant of the 7900.


Flipping the card over to the backside of the PCB, there is a great deal of stickers as well as other circuitry. For most enthusiasts, it is very nonchalant. The stickers contain the following the part information and BIOS -- e-GeForce 7900GT CO SC 256-P2-N565-AX and BIOS v5.71.22.12.02. According to board markings, the PCB was manufactured in Taiwan while a sticker appears to suggest other portions were made in China. From this side of the board, the four heatsink mounts can also be found.
