PowerColor Hellhound Spectral White AMD Radeon RX 7900XT Graphics Card 20GB GDDR6

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 brand new white heatsink with closely spaced vertical fins is mounted on the PCB, offering a larger heat-spreading area and improved heat radiation. This allows airflow to efficiently disperse heat.

Turbulence Reducing Fan Rotation

The middle fan spins in the reverse direction so as to reduce the air turbulence between neighboring fans when drawing in cool air. The mechanism therefore maximizes the air flow and pressure when less turbulence occurs to offset, further lowering noise level without sacrificing cooling efficiency.

Car-Grade Power Module DrMOS with iMON Real Time Digital Monitoring

Hellhound adopts a 10+3+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, the high quality car-grade polymer capacitors feature long-lasting durability, and the 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 XT; a PCB such designed decreases signal loss during transmission, which is important especially for higher-end GPUs with increased demands for higher currents and stability.

Anti-Sag Bracket

A robust metal bracket is installed on the side of the PCB and is supported all the way to the I/O plate, making the card stand firmly in place inside the chassis.

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.

Ice Blue and Glacier White LED Color

Hellhound of this generation now comes with two LED color options. Gamers are able to choose the color they want by flipping the switch on side of the card.

Ice Blue shows the Hellhound's coolness, while Glacier White projects a crisp, calm elegance.

Dual BIOS Mode

Hellhound RX 7900 XT 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.
