MSI Unveils RTX 5090 Lightning With Next-Gen AIO Cooling and 1,600W Design

MSI lists a 1600W design with an XOC BIOS enabling up to 2500W.

Overview

  • The company presented the co-developed-with-NVIDIA flagship at CES 2026, featuring a new liquid-cooling system, a compact shroud, and a full-surface LCD.
  • MSI’s materials describe a reinforced PCB with roughly 40 VRM phases and two 16-pin power connectors.
  • Official documentation rates the card for up to 1600W, while an overclocker-posted XOC BIOS shows limits as high as 2500W.
  • Engineering “OCER” units enabled overclockers to set multiple benchmark records under LN2, reaching about 3.75 GHz on the core and roughly 36 Gbps on GDDR7.
  • MSI and overclockers indicate the OCER hardware is non-retail, and early photos showed differing connector descriptions that may not match the finalized card.
