eVGA e-GeForce 7800GT CO 256MB
With the eVGA e-GeForce 7800GT CO running at a magnificent 470/1100MHz against the stock 400/1000MHz we expected to see a much more extravagant cooling system onboard, considering even the BFG Technology 7800GT OC only manages to run its factory overclocked card at 425/1050MHz, but the overall design of the eVGA heatsink is somewhat representative of NVIDIA's reference design. Assisting in the dissipation of heat is all copper construction used on the heatsink as well as what appears to be a slightly larger fan that has been adopted from the 7800GTX 256MB model. Printed on top of the heatsink is eVGA along with intelligent innovation and eVGA's rather large logo. The heatsink is similar to their 7800GTX 256MB part, excluding KO and ACS2 SKUs, as well as the 7800GTX CO SE.

Next to the single-slot heatsink that covers up a majority of the green PCB is a fair amount of voltage regulation module circuitry as well as a 6-pin PCI Express power connector. The power connector is used to supplement additional 12V power for the graphics card, as simply the PCI Express x16 slot itself cannot provide the necessary amount. Speaking of which, eVGA recommends at least a 450W PSU for adequate operation and the power supplies that do not offer native PCI-E support, a PCI Express power adapter is included that runs off two 4-pin molex connectors. In addition to the PCI Express x16 interface is NVIDIA's exclusive Scalable Link Interface connector thus readying it for SLI action. The overall size of the card is a few centimeters shorter than that of a GeForce 7800GTX and thanks to its single-slot cooler it should have no problems fitting inside SFF PCs. At the opposite end of the graphics card are two DVI connectors along with the VIVO interface.

Flipping over the heatsink we see how the heatsink is mounted with pushpins and a retention frame over the opposite side of the GPU. At the rear, and all over the PCB for that matter, there continues to be a fair amount of power circuitry. On the rear of the PCB are also two stickers containing the product information and video BIOS version. The part number of the 256MB unit we are testing today is 256-P2-N517-AX. The BIOS installed on the eVGA card is 5.70.02.13.02. Except for a few alterations with the heatsink, and the factory overclock, the eVGA e-GeForce 7800GT 256MB CO sticks fairly close by NVIDIA's reference design.
