Product Positioning

The PowerColor Hellhound Radeon RX 7800 XT is a graphics card built for 1440p and 4K gaming with its 16GB GDDR6 frame buffer. It connects through a PCI Express 4.0 x16 slot and draws up to 263W, so a 750W power supply is recommended. The triple-fan cooler handles the thermal load of the RDNA 3 architecture across 3840 stream processors.

Sustained Load Behaviour

Under continuous load the GPU operates at a 2213 MHz game clock and can reach a 2520 MHz boost clock when thermal headroom allows. The 256-bit memory interface keeps bandwidth stable during extended sessions at 7680 x 4320 resolution. DirectX 12 Ultimate and OpenGL 4.6 support remain consistent throughout heavy compute or rasterisation workloads.

Build and Connectivity

The card occupies 2.5 slots and measures 332 mm in length, fitting standard ATX chassis with adequate clearance. Outputs include one HDMI 2.1 port and three DisplayPort 2.1 connectors, enabling four simultaneous displays. The metal backplate adds rigidity and helps dissipate heat from the memory modules.

Questions about this item

How much power does the 263W TDP card draw and what PSU is recommended for all-day loads?

The card has a 263W thermal design power and the maker recommends a 750W supply for sustained operation.

Does my motherboard need a PCIe 4.0 x16 slot and a case that fits a 332mm, 2.5-slot ATX board?

Yes, the interface is PCI Express 4.0 x16 and the cooler measures 332mm long by 2.5 slots wide in an ATX form factor.

Will my older DisplayPort 1.4 monitor work with the three DisplayPort 2.1 outputs?

DisplayPort 2.1 is backwards compatible, so a DisplayPort 1.4 display will run at its native capability.
