24GB Radeon RX 7900 XTX for 4K gaming

The GIGABYTE GV-R79XTXGAMING OC-24GD is a PCI Express 4.0 x16 graphics card built on the AMD Radeon RX 7000 Series architecture. It delivers 24GB of GDDR6 memory across a 384-Bit interface and 6144 stream processors. The card targets enthusiasts who need high frame rates at 7680 x 4320 resolution across up to four displays.

Sustained load behaviour with 355W TDP

Under continuous load the 355W thermal design power demands an 850W power supply and two 8-Pin connectors. The triple-fan cooler moves heat away from the GPU during extended sessions, keeping clocks stable when the 384-Bit memory bus is fully utilised. Thermal throttling is reduced because the cooler is designed for the full power envelope rather than short bursts.

Installation notes for a 331 mm triple-slot card

The ATX form factor measures 331 mm in length and occupies three expansion slots, so verify case clearance before fitting. Two 8-Pin power cables must be routed cleanly to avoid bending near the connector shroud. Driver installation follows the standard AMD Radeon software stack; the only common issue is insufficient PSU headroom when the 355W limit is reached.

Questions about this item

How much heat does the 355W TDP triple-fan cooler push into the case during all-day loads?

The card has a 355W thermal design power and uses a triple-fan cooler to exhaust that heat; ensure your chassis airflow can move the equivalent energy out of the case.

Which power connectors and PSU headroom does the 850W recommendation assume?

The board draws power through two 8-pin connectors and the manufacturer recommends an 850W supply to cover the 355W TDP plus the rest of the system.

Will the 331 mm length and three-slot width fit alongside my existing ATX motherboard and drive cages?

The card measures 331 mm long and occupies three expansion slots, so verify clearance from front-panel connectors, drive bays and CPU cooler before installing.
