Acer Nitro Intel Arc B580 12GB
This refurbished graphics card uses the Intel Arc B580 GPU with 20 Xe-cores and 20 ray tracing units. It carries 12GB of GDDR6 memory on a 192-bit bus running at 19000 MHz effective. The board connects through a PCI Express 4.0 x8 interface and has a 205W thermal design power.
Sustained load behaviour
The air cooler must dissipate 205W continuously, so case airflow becomes the limiting factor during long sessions. Core clocks hold at 2740 MHz while the memory sustains 19000 MHz, delivering 456Gb/s bandwidth for compute or 4K gaming. DirectX 12 Ultimate and OpenGL 4.6 support remain stable under prolonged draw.
Installation notes
A 600W supply with one 8-pin PCIe connector is required, plus a motherboard with an x16 slot and Resizable BAR or Smart Access Memory enabled. Windows 10 or 11 64-bit and at least 8GB system memory are needed, 16GB recommended. The card outputs through one HDMI 2.1 and three DisplayPort 2.1 connectors for up to four monitors.

Questions about this item
How much heat does the 205W air cooler have to move when the card runs all day?
The card draws up to 205W, so the air cooler must dissipate that sustained thermal load during long sessions.
Which power connector and PSU capacity does the DP.Z4BWW.P01 require?
It needs one 8-pin PCIe connector and a minimum 600W power supply to operate.
Will the PCI Express 4.0 x8 interface limit performance on a PCIe 3.0 motherboard?
The card runs on PCIe 4.0 x8 but is backward compatible with PCIe 3.0 x16 slots; bandwidth scales to the slot capability.
