Even though NVIDIA's GeForce GTX 690 graphics card is already a mighty beast, ASUS has been determined to overshadow it for weeks.
The Mars III
board, revealed at Computex 2012, is a GTX 690 with better power supply circuits, but this only came to light recently, when someone on the Expreview forums
provided some photos of the PCB.
The 8 GB of GDDR5 VRAM, the 256-bit interface and the two GK104 GPUs get energy through an 8+2-phase VRM (20 phases in total).
A couple of 8-pin PCI Express power plugs bring the electricity from the PSU to the add-in card.
All in all, the video board should consume more than 500W of energy when pushed to its best.
The cooler is the same one as previously seen: a dual-slot module with an aluminum fin array, copper heatpipes and three PWM-controlled fans.
No word on the clocks or the price.
