A Closer Look

Graphics Card Cooler Front
Graphics Card Cooler Back

ZOTAC's cooler is a basic piece of metal, no fancy heatpipes. Due to the low heat output of the GPU these are not needed anyway.

Graphics Card Power Plugs

The card requires no additional PCI-Express power connectors, all power is supplied via the PCIe bus. This configuration is good for up to 75 W of power draw.


ZOTAC uses a uP1529 voltage controller on their card. This is the first time that I see this chip and there is no info available online. Given its compact footprint and limited number of input pins I seriously doubt that it supports software voltage control.

Graphics Card Memory Chips

The DDR3 memory chips are made by Micron, and carry the model number MT41J128M16JT-107. They are specified to run at 933 MHz (1866 MHz DDR3 effective).

Graphics Chip GPU

NVIDIA's new GK107 graphics processor is the company's second Kepler GPU, just like GK104 it is made on a 28 nanometer process at TSMC Taiwan. Details like chip size and transistor count have not been revealed by NVIDIA.
