Refurbished Intel Arc B580 graphics card
This ONIX LUMI card is a refurbished GPU built on the Intel Arc B580 chipset with 20 Xe-cores and a 2740 MHz core clock. It targets 1440p gamers and content creators who want modern media engines and 12 GB of GDDR6 memory on a PCI Express 4.0 x8 interface. The white dual-fan cooler fits a standard ATX slot.
Upgrade from 8 GB or older mid-range GPUs
Moving from an 8 GB card removes the texture-memory ceiling that forces quality cuts in current titles. The 192-bit bus and 19000 MHz effective clock deliver enough bandwidth for high-refresh 1440p play, while DirectX 12 Ultimate and OpenGL 4.6 support current API features. The jump is worth it when your present card stutters on 12 GB texture packs.
12 GB GDDR6 handles 1440p ultra and light 4K
The 12 GB frame buffer comfortably runs modern games at 1440p ultra settings and supports entry-level 4K workloads such as video editing timelines or compute tasks. At 203 W TDP with a single 8-pin connector and a 600 W PSU recommendation, power headroom is modest. Four display outputs (HDMI 2.1 plus three DisplayPort 2.1) drive multi-monitor setups up to 7680 x 4320.

이 상품에 대한 질문
Will the 260 mm length and 2.2 slot width fit my ATX case and motherboard spacing?
The card measures 260 mm long, 130 mm tall and 52 mm thick, occupying 2.2 slots; verify your case clearance and that adjacent PCIe slots stay free.
Which power connector does the 203 W TDP require and what PSU headroom is advised?
It needs a single 8‑pin PCIe power connector and a 600 W or larger PSU; connect the cable directly from the PSU, not via a daisy‑chain adapter.
How often should I clean the dual fans to keep the 203 W thermal load under control?
Use compressed air on the two fans every three to six months, depending on dust levels, to maintain airflow across the heatsink.
