ONIX ODYSSEY Arc B580 8346-00178 graphics card

Refurbished Arc B580 for 1440p Gaming

The ONIX ODYSSEY Arc B580 is a refurbished graphics card built around the Intel Arc B580 GPU with 20 Xe-cores and a 2670 MHz core clock. It carries 12GB of GDDR6 memory across a 192-Bit interface running at 19000 MHz effective speed. The PCI Express 4.0 x8 interface connects to a standard ATX board, while one HDMI 2.1 and three DisplayPort 2.1 outputs drive up to four displays at 7680 x 4320 resolution.

Sustained Load Behaviour on 190W TDP

With a Thermal Design Power of 190W and a single 8-Pin power connector, the card draws steady power through extended gaming or compute sessions. The 12GB frame buffer and 192-Bit bus keep texture streaming consistent when workloads exceed short bursts, while the 2670 MHz clock holds stable under the 600W recommended PSU headroom. Driver support for DirectX 12 Ultimate and OpenGL 4.6 maintains API compatibility throughout long runs.

Dual-Fan Cooling in a 2.2-Slot ATX Form Factor

A double-fan cooler exhausts heat inside a 260 x 130 x 52 mm black shroud that occupies 2.2 expansion slots. The 260 mm length fits most mid-tower cases while the dual fans manage the 190W thermal load at moderate acoustic levels during typical 1440p gaming. Power draw stays at the rated 190W under normal use, leaving margin within the 600W supply recommendation for the rest of the system.
