Features
The Hellhound Gaming Experience
Hellhound has long been guarding the gaming underworld and is committed to deliver the most reliable gaming experience. Remain simple and sleek; it is never humble in showing its strength when the gamers calls for. The Hellhound of this generation features a second LED colour – amethyst purple—to provide a different atmosphere in your PC build.
Engineered for Performance and Reliability
The PowerColor Hellhound RX 7900 GRE adopts a triple ringed-fan solution (100 x 90 x 100mm), a set of 5 x 6φ heatpipes running through the heatsink, and a copper plate directly touching the GPU while covering VRAM to achieve better cooling efficiency. In addition, the product is built with 15 phase (9+2+1+2+1) phase VRM design and DrMOS that comes with IMON real-time digital monitoring, aiming at providing reliable performance output during gaming.

High Quality Japanese Dual Ball Bearings
Dual ball bearings reduce rotational friction, providing excellent heat dissipation and effectively doubling the expected lifetime of the fans.
Intelligent Fan Controller
Utilizing temperature detection from a smart chip, fans will start running when the GPU reaches 60℃ and shut down below 50℃. Efficient cooling, fan-noise reduction, and extended product lifetime are all benefits of a more accurate temperature monitoring.
Unprecedented Ring-Fan Blade Design
The newest 9-blade design of our fans generate better airflow and air pressure under the same noise level, improving cooling performance to reduce GPU temperatures by more than 3℃ compared to previous generations.
GPU Direct-Contact Copper Plate
We have increased the copper plate area to provide direct contact with the GPU while covering VRAM to increase the heat transfer threshold to the max.
Vertical Fin Heatsink
A large heatsink with vertical fins spaced closely is mounted on PCB and offers better heat-spread area and radiation, allowing airflow to disperse heat efficiently.
Turbulence Reducing Fan Rotation
The middle fan spins in the reverse way so as to reduce the air turbulence between neighbouring fans when drawing in cool air. The mechanism therefore maximizes the air flow and pressure when less turbulence occurs to offset, further to lower the noise level without sacrificing the cooling efficiency.
Optimum Heatpipe Arrangement
A set of 5 x 6φ nickel-plated copper heatpipes align closely above the PCB to more quickly and effectively transfer heat from the GPU and VRAM to the cooling array.
Car-Grade Power Module DrMOS with iMON Real Time Digital Monitoring
Hellhound adopts a 9+2+1 phase VRM design with DrMOS to power the GPU as well as an additional 2+1 phase specifically designated for the VRAM. New IMON technology monitors and reports the electric current and power consumption on each individual phase. By balancing the workload, the Hellhound ensures unparalleled stability and thermal protection during overclocking.
In addition, high quality car-grade polymer capacitors features long-lasting durability and high conductivity lowers power loss during transmission.
High Quality PCB Design
A premium 14-layer high TG PCB Board -including a 2 oz power layer- is utilized in the Hellhound RX 7900 GRE; a PCB such designed decreases signal loss during transmission: important especially for higher-end GPUs with increased demands for higher currents and stability.
Metal Reinforced Backplate
The metal backplate strengthens and protects the internal components from PCB bend, and a cut-out design on the back plate allows exhaust heat to properly flow through for heat-dissipation efficiency.
Brand New Amethyst LED Colour
Hellhound of this generation comes with a brand new amethyst purple LED lighting while retaining the previous ice blue. Gamers are able to choose the colour they want by flipping the switch on side of the card.
Ice blue shows coolness and elegance while amethyst represents mystery and charm.
Dual BIOS Mode
Hellhound RX 7900 GRE features Dual BIOS built-in and a switch for easy swapping.
- OC BIOS: A boosted mode that increases fan RPM to keep your card operating at a lower temperature to drive higher performance.
- Silent BIOS: Focused on lower noise and fan longevity, a milder fan speed, trading fan speed and noise for moderate, but still controlled, temperatures while maintaining performance.
