Listing is for (1) AMD Radeon RX 550 4GB GDDR5 PCIe DisplayPort, 2 x Mini DisplayPort Low Profile Graphics Card.
Used in a Dell Optiplex 5050, HP Z440 and a HP 800 G3 with no problems. AMD does a good job when updating drivers on the regular.
Bought a new A2000 so this RX 550 is ready for a new owner.
My loss your gain. Buy it today.
