Product identity

The PowerColor RX 550 is a low-profile graphics card with 4 GB of GDDR5 memory. It targets users who need a basic display upgrade for compact PCs or secondary systems. The GPU provides 512 stream processors and a 128-bit memory interface for everyday workloads.

Build and connectors

The card measures 181 by 120 by 20 mm and draws power solely from the PCIe 3.0 slot, so no extra power cable is required. Outputs include a single-link DVI-D port and an HDMI port for straightforward monitor connections.

Practical limits

A 250 W system power supply is the minimum recommended by the manufacturer. Maximum digital resolution reaches 4096 by 2160 over HDMI and 2560 by 1600 over DVI. DirectX 12 and OpenGL support cover common desktop and light gaming scenarios.

Questions about this item

What PCIe 3.0 lane width does the card use, and what bandwidth ceiling does that impose?

The card runs on a PCIe 3.0 x16 slot, which caps real-world throughput at the 128-bit memory interface and 6.0 Gbps GDDR5 speed rather than the bus itself.

Will the 181 mm by 120 mm low-profile board fit inside my slim chassis?

The 181 mm length, 120 mm height and 20 mm thickness match standard low-profile brackets, so it fits most slim cases that accept half-height cards.

How do I install the card without external power, and what step is often missed?

Seat the card in the PCIe 3.0 slot, secure the low-profile bracket screw, connect the display cable, then install the AMD driver; the step often missed is enabling the discrete GPU in BIOS when integrated graphics are present.
