ASUS ROG Mars II 3GB – A Mini Review
The card takes up three slots and measures 13 inch x 6.2 inch x 2.5 inch, which means it will only fit in large Extended ATX cases or open-air setups. This complicates multi-card SLi and restricts air flow on some motherboards (ASUS provides a 12cm SLI bridge).
Inheriting the design and red-black colour scheme of the current range of Republic Of Gamers products, the Mars II looks great in any enthusiast's setup and would compliment their ASUS ROG range of motherboards.
The grooves and ridges on the Mars II shroud were designed to look like the heat pipe coolers on ROG motherboards.
Power Circuitry – "21 Phase Super Alloy Power"
Comprising of 21 phases of power, "Super Alloy" MOSes, Chokes and Capacitors, the use of these components purportedly reduce overall power loss, enhance durability and achieve cooler temperatures over Nvidia reference designs.
One NEC Proadlizer is used for each GPU.
To help cool this beast, each heatsink has four copper heatpipes.
The dual 120mm fans that we see on the Mars II is the largest air cooling design we have ever encountered in a retail graphics card. They push a lot of air at high RPMs and were generally silent in normal operation.
