Cleaned, inspected, and tested in the workshop.
😊 In plain words
An older graphics card for $20 to provide backup display or add video outputs to a compatible desktop tower. It has 1 GB of video memory and the following listed outputs: two DVI-I, one HDMI, and one DisplayPort. Four ports do not mean four screens at the same time.
“HD 5800 Series” is the family name displayed in Windows. The exact model and manufacturer are not identified here. We therefore do not list it as an HD 5850 or an HD 5870.
Check before purchase: space for a full-height card, PCIe x16 slot, and two 6-pin PCIe power connectors. The listing recommends a high-quality 500 W power supply for the complete PC; its listed power alone is not enough to confirm compatibility.
Tested under Windows 11 by the workshop. A suitable driver must be installed on your PC. Its older drivers and 1 GB of memory make it a backup choice rather than a card for recent games. Card sold separately with protective packaging and a 30-day limited warranty from the date of billing.

- Classic games and emulation: possibilities to be verified depending on title, version, CPU, and RAM; the release year alone does not guarantee operation.

❓ Frequently Asked Questions
Is it an HD 5850 or an HD 5870?
The HD 5800 Series name in Windows does not allow us to distinguish. No exact model or MPN is provided here.
Can I connect four monitors?
Four ports are not enough to guarantee it. Have the combination and the need for a DisplayPort connection or a suitable active adapter checked.
Is a 500 W power supply sufficient?
The listed power alone is not enough: quality, actual capacity, two 6-pin PCIe connectors, and the rest of the PC must be suitable.
Does the 256-bit bus guarantee double performance?
No. Architecture, frequencies, memory, drivers, and application also influence the result.
