New Atmosphere of Hellhound

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 two LED color options. – glacier white—to

provide a different atmosphere in your PC build.

Engineered for Performance and Reliability

The PowerColor Hellhound RX 7900 XTX adopts a triple ringed-

fan solution (100 x 90 x 100mm), a set of 8 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

12+3+2+2+1 phase VRM design and DrMOS that comes with

IMON real-time digital monitoring, aiming at providing reliable

performance output during gaming.

3. High Quality

4. DrMOS with IMON Digital Monitoring

5. Optimum Heatpipe Arrangement

6. Ice Blue and Glacier White LED Color

7. Ring-fan Blade Design

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 neighboring 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 8 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 12+3+2 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 XTX; a PCB such

designed decreases signal loss during transmission: 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

represents its elegance and calmness.

Dual BIOS Mode

Hellhound RX 7900 XTX 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.
