Hellhound RX 7900 XTX 24GB for 4K gaming

The PowerColor Hellhound RX 7900 XTX 24G-L/OC/WHITE is a factory-overclocked Radeon RX 7900 XTX graphics card built for 4K gaming workloads. It uses the AMD RDNA 3 architecture with 6144 stream processors and 24GB of GDDR6 memory on a 384-bit bus. A PCI Express 4.0 interface connects the card to the platform. The white finish suits light-themed builds.

Sustained load behaviour at 2525 MHz boost

The GPU runs at a 2330 MHz game clock and can reach a 2525 MHz boost clock during extended sessions. Memory operates at an effective 20000 MHz, providing high bandwidth for texture-heavy titles. The 355 W thermal design power rating reflects the energy budget under continuous load. An 800 W power supply is recommended to support the board and its two 8-pin connectors.

Triple-fan cooling with 355 W TDP

A triple-fan cooler dissipates the 355 W TDP across a three-slot ATX form factor that measures 320 mm in length. The card draws power through two 8-pin connectors while maintaining operational temperatures. Display outputs comprise one HDMI 2.1 port and three DisplayPort 2.1 connectors, supporting up to 7680 x 4320 resolution across four monitors.

Questions about this item

How much heat does the 355W TDP produce during all-day loads?

The card is rated at 355W TDP, so sustained workloads will push that much heat into the case; a triple-fan cooler is fitted to move it away from the GPU.

What power supply and connectors must I already have?

A minimum 800W PSU with two 8-pin PCIe power cables is required for the 355W board.

Will the 320mm length and three-slot width fit next to my older PCIe 3.0 motherboard?

It installs in any PCI Express 4.0 slot and is backward compatible with PCIe 3.0 boards, provided the case clears 320mm and three expansion slots.
