GALAX unveiled its Boomstar series graphics card, introducing two RTX 5090D variants, LUNA and NOX, exclusively for the Chinese market. Both models share identical specifications, differing only in aesthetics: LUNA sports an all-white finish, while NOX adopts a matte black look. At the heart of each Boomstar card lies NVIDIA's GeForce RTX 5090D GPU, factory-overclocked to a 2,452 MHz boost clock, up from the reference 2,407 MHz. Power delivery is handled by a robust 16+6+7 phase VRM on a 14-layer PCB, with the card's total thermal design power rated at 575 W. GALAX recommends pairing the Boomstar series with a 1,000 W power supply, utilizing the latest 12 V-2×6-pin connector standard to ensure stability under full load. Display connectivity comprises three DisplayPort 2.1b outputs alongside a single HDMI 2.1b port, enabling multi-monitor and high-refresh-rate setups.

Measuring 348 × 155 × 60 mm (including bracket), the triple-slot, triple-fan cooler departs from conventional designs by employing magnetic attachments for both shroud and backplate. This tool-free system allows users to lift off the entire fan assembly without screws or cables, simplifying dust removal and maintenance. GALAX confirms that detaching these magnetized components does not void the warranty, although it cautions against removal while the card is operational. Out of the box, each card includes one customizable magnetic sticker, part of Boomstar's signature interchangeable panel concept. GALAX has yet to clarify whether additional sticker packs will be sold separately. GALAX has not disclosed pricing or availability timelines but confirms that Boomstar LUNA and NOX will remain confined to China, with no non-D variant planned for other regions.
