Boasting 3x Displayport and 1x HDMI Connections allowing a maximum of 4 concurrent displays.

Innovative cooling technologies to ensure optimal performance and airflow.

Hybrid Fan Blades
The new hybrid fan design combines the quietness of a traditional axial fan design and strong air pressure of a blower fan design to generate an improvement in the downward air pressure through the fan while keeping the fan noise low.

High Performance Cooling
To cool the GPU, the pump/heat spreader of the liquid cooling system on TOXIC effectively removes the heat from the GPU to the 360 mm radiator for heat exchange

VRM/Memory Cooling
On the VRM/Memory cooling, the new hybrid fan blows away the heat transferred by the die-cast heatsink with heatpipes from the memory and VRM components

Consistent & Quiet
The hot liquid is cooled in the radiator by 3x 120mm fans and pushed back to the pump/spreader, keeping the GPU temp lower than 70°C and noise output below 34dBA
