ASUS is on the verge of launching their next addition in the ROG GeForce graphics card lineup, the ROG Poseidon GTX 980. Featuring the republic of gamers brand, Poseidon GTX 980 will stick with the reference technical specifications of the GeForce GTX 980 while feature faster clock speeds, a customized PCB design followed with a Hybrid DirectCU H2O liquid cooler which was introduced on the GeForce GTX 780 last year.

So quickly summing up the specifications, the Poseidon GTX 980 features the GM204-400-A1 core which includes 2048 CUDA Cores, 128 texture mapping units and 64 raster operation units. The card has a 4 GB GDDR5 memory which runs across a 256-bit memory interface and is clocked at 7.01 GHz effective clock frequency. The core clocks are maintained at 1178 MHz core and 1279 MHz boost clock. Being one of NVIDIA’s most power efficient chip, the GTX 980 is a juggernaut of performance and power with ASUS taking it one step further with their own customized PCB design which pushes more power to the core and memory for better overclocking support.

To suit overclocking and performance needs, the card is fitted with a custom designed PCB featuring the DIGI+ VRM with a 10 Phase PWM supply which pushes power through a 6+8 Pin power configuration. The card fits in at dimensions of 11.3×5.4×1.6 inches. One of the features touted by ASUS is that the black metallic capacitors used on the PCB reduce noise power by 30% and enhance efficiency up to 15% while increasing stability and lifetime of the card.

Talking about the cooler itself, the design is little changed from the previous Poseidon card. It features the black and red color scheme on the shroud. There are strikes of red on the front and back while the ROG cut outs give a decent look. The cooler shroud sticks with the ASUS ROG black and red color theme while the dual fans push air towards the center of the large aluminum fin array with heatpipe design. But since the ROG GTX 980 Poseidon will be a hybrid design, you can select to use Air cooling, Water Cooling or both which is effective. The Direct contact base comes with a metal bracket which is pretty large and features two inlets provide water flow that transfers coolant to the copper base. Plus that ROG emblem on the side is a pulsating LED which will glow in red when under operation. An additional feature is a sexy ROG backplate used on the back side of the PCB which adds to the aesthetics of the card.


Finally, we have five display ports which we have seen on reference GTX 980 boards. These include three display ports, one HDMI and a single Display port. The card is expected to launch on December 12th 2014, pricing hasn’t been confirmed yet but expect a premium over the reference model. Full specifications can be found below:
