At the 2026 International CES show, MSI unveiled its most powerful GPU creation to date: GeForce RTX 5090 Lightning Z GPU. Coming as a fully custom PCB design, the board carries an GB202 GPU of the RTX 5090 with a factory boost clock of 2,730 MHz, and an "Extreme Performance" OC profile of 2,775 MHz. This results in the fastest LN2 GeForce RTX 5090 GPU ever, reaching as high as 3,742 MHz when put thought the hands of professional overclockers. Fully enabling this is the 40-phase VRM design that can provide smooth voltage curve needed to feed the GPU, with a maximum power rating of 800 W out of the box, while the "Extreme" power preset mode gives it a 1000 W power envelope on the 360 mm AIO water cooling. The card is powered by dual 16-pin 12V-2x6 power connectors, each giving the maximum of 600 W.

MSI has used the 28 Gbps Samsung GDDR7 modules, which can be overclocked to 36 Gbps on LN2, and probably at 30+ Gbps on the standard watercooling. In its regular form factor that comes from the factory, MSI has made the GPU appear as a small tablet device with its big screen. All you see is the yellow theme of the card and two tubes connected to the 360 mm radiator that dissipates a kilowatt of heat. In addition to the massive radiator, the GPU is covered in full-copper cold plate that entirely covers the PCB, cooling the GPU, VRMs, and memory for a true all-in-one cooling. The pictures follow below.
