RED DEVIL Radeon RX 7900 XT with 20GB GDDR6

This PowerColor graphics card targets enthusiasts who need high frame rates at 4K and headroom for compute workloads. The AMD Radeon RX 7900 XT GPU delivers 5376 stream processors and a 320-bit memory interface. A game clock of 2175 MHz and boost clock of 2535 MHz provide strong baseline performance. The PCI Express 4.0 interface ensures full bandwidth on modern platforms.

Sustained load behaviour with 300W thermal design

The card draws up to 300W under continuous load, so an 850W power supply is recommended. Two 8-pin connectors feed the board, keeping voltage stable during long rendering or gaming sessions. Triple fans move air across a large heatsink to maintain the 2535 MHz boost clock without throttling. The 4-slot ATX form factor occupies significant chassis space but aids heat dissipation.

Build quality and daily connectivity

A metal backplate stiffens the 338 mm PCB and protects components during handling. One HDMI 2.1 port and three DisplayPort 2.1 outputs drive up to four displays at 7680 x 4320 resolution. The bracket follows standard ATX mounting, so installation fits typical cases that clear the length and slot width. DirectX 12 and OpenGL 4.6 support cover current and legacy APIs.

Questions about this item

How loud and hot does the triple-fan RED DEVIL cooler run when the card draws its 300W TDP all day?

The triple-fan cooler is designed to dissipate the 300W thermal design power; actual noise and temperature depend on case airflow and fan-curve settings.

My power supply only has one 8-pin PCIe cable — will the card work with a single connector?

The board requires two 8-pin PCIe power connectors and the manufacturer recommends an 850W supply, so a single cable is not sufficient.

Will the 338 mm length and four-slot thickness fit alongside my existing ATX motherboard and CPU cooler?

The card uses a standard ATX form factor measuring 338 mm long and occupying four expansion slots; verify your case clearance and motherboard layout before installing.
