PowerColor Hellhound Radeon RX 6600 XT 8GB GDDR6

This PowerColor Hellhound Radeon RX 6600 XT graphics card delivers 8GB of GDDR6 memory on a 128-bit interface for 1080p gaming. It suits builders wanting a dual-fan ATX card with factory overclock profiles. The Radeon GPU provides 2048 stream processors and supports DirectX 12 Ultimate for modern titles.

PCI Express 4.0 interface

Verify your motherboard has a PCI Express 4.0 x16 slot and that your power supply meets the 500 watt recommendation with an available 8-pin PCIe power connector. The card draws up to 160W thermal design power under load. Ensure the case can accommodate a 220mm maximum GPU length and a 2.2-slot width bracket.

Dual-fan cooler frees up case airflow for compact

The double-fan thermal solution exhausts heat into the chassis, so plan front-to-rear airflow to keep temperatures stable. One HDMI 2.1 and three DisplayPort 1.4 outputs drive up to four monitors simultaneously. Virtual reality readiness lets you connect a headset without extra adapters. The ATX form factor fits standard mid-tower and larger cases.
