RED DEVIL RX 6600 XT for 1080p gaming

The PowerColor RED DEVIL Radeon RX 6600 XT is a refurbished graphics card built around the AMD Radeon RX 6600 XT GPU with 2048 stream processors and 8GB of GDDR6 memory on a 128-bit bus. It connects via PCI Express 4.0 and drives up to four displays through one HDMI 2.1 port and three DisplayPort 1.4 outputs. The card targets gamers who want high frame rates at 1080p resolution.

Sustained load behaviour with dual-fan cooler

A 2.5-slot dual-fan cooler manages the 160W thermal design power during extended sessions. The BIOS offers two profiles: an OC mode with a game clock of 2428MHz and boost to 2607MHz, and a Silent mode with a game clock of 2382MHz and boost to 2593MHz. Memory runs at 16.0Gbps effective in both profiles, delivering steady bandwidth for prolonged 1080p workloads.

Check PSU connectors and case clearance

The board requires one 6-pin and one 8-pin power connector and the manufacturer recommends a 600W power supply. Physical length is 252mm and the 2.5-slot thickness may block adjacent expansion slots, so verify case clearance and motherboard layout before ordering. The card supports DirectX 12 Ultimate and OpenGL 4.6 for modern API compatibility.

Questions about this item

How much heat does the 160W RED DEVIL card produce and what PSU is recommended?

The card has a 160W thermal design power and the manufacturer recommends a 600W power supply for stable operation.

My PSU only has one 8-pin connector — will the 6-pin plus 8-pin requirement work?

The board needs both a 6-pin and an 8-pin PCIe power connector; a single 8-pin alone is not sufficient.

Will the 252 mm length and 2.5-slot width fit alongside my older ATX motherboard and case?

It uses a standard ATX form factor, 252 mm length and 2.5-slot thickness, so it fits most ATX cases with adequate clearance.
