What power supply do I need for the ASRock Arc B580 Steel Legend?
ASRock recommends a power supply of at least 600W. Make sure your PSU has the right PCIe power connectors before you install the card.
How much VRAM does this card have, and how fast is it?
It has 12GB of GDDR6 on a 192-bit memory bus, with a 19 Gbps memory clock.
