Chinese board partner Maxsun introduced its flagship—Mega Gamer GPU (MGG)—GeForce RTX 40-series lineup earlier this year, debuting with an RTX 4070 Ti card, and then an RTX 4080 MGG OC 16G model. The rather unique looking cooling solution attracted some attention at the time—a traditional set of three 100 mm fans was augmented with two additional 40 mm "Air Burst" units in a flanking position, acting as exhausts as for the finstack. Earlier today Maxsun revealed the range topping RTX 4090 MGG OC 24G model via a video uploaded to their Weibo channel.

The new headliner looks to be fitted with the same shroud design as seen on the already released RTX 4080 MGG OC 16G model, which includes a somewhat gimmicky magnetically detachable large top-facing RGB LED panel, dubbed "MGG LED Ambient Kit." Thankfully Maxsun has put the work into creating a robust cooling solution, with a vapor chamber capable of meting out 7000 mm² of heat dissipation. Their GeForce RTX 4090 MGG OC 24G model's TDP has been rated at 450 W TDP, with a factory overclock providing a 2580 MHz boost clock. As reported by VideoCardz, Maxsun seems to be sticking to a Chinese market launch for the moment—the company's international AliExpress store has not been updated with a listing for the range topping Mega Gamer GPU.
