The VisionTek OCPC Radeon RX 550 4GB graphics card is ideal for entertainment and value gaming PCs. With 4K resolution support, the RX 550 is a perfect upgrade to enhance your PC's visual experience. No additional power is required, making this card ideal for small form factor systems with limited power supply options. Single Slot The RX 550 fits a full height or small form factor system and features DisplayPort and HDMI ports in a single slot. High Speed Memory The RX 550 uses 4GB of high bandwidth GDDR5 memory to deliver lag-free content with the highest resolution possible. Low Power Thanks to an energy efficient design, the RX 550 requires only 50 watts of power so it can be run off the system power bus. With most systems featuring a factory-installed 350 watt or higher power supply, you don't have to purchase and install a larger power supply.
