MSI just dropped a monster GPU, and it drinks power like crazy. The freshly announced RTX 5090 Lightning Z is their limited-edition flagship, pushing up to a thousand watts. This card is built for extreme overclocking with a wild 40-phase VRM design and multiple power modes. A standard overclock pushes 800 watts, while an Extreme Mode lets it hit that full 1000W draw. There is even a separate 2500W BIOS for competitive overclockers, which instantly voids the warranty. MSI suggests using a power supply of 1600 watts or more with this thing.
Cooling this beast requires serious hardware. The card uses a sealed liquid cooling system with a 360 millimeter radiator. Its main innovation is a full-copper base plate that directly contacts the GPU, memory, and power delivery components. The shroud keeps a relatively compact 2.5-slot thickness, sporting the classic Lightning black and yellow color scheme. Other cooling features include a specialized radiator fin design, an updated pump for better flow, and a carbon fiber backplate.
A huge selling point is the built-in 8-inch screen on the card itself. This display is bigger than most phone screens and can show system stats or custom graphics. For performance, the listed boost clock is 2730 MHz, with a software toggle bumping it to 2775 MHz. Leaked overclocks show enthusiasts pushing frequencies nearly a gigahertz higher, far beyond the factory specs.
The company confirmed that only 1300 units of the GeForce RTX 5090 Lightning Z will ever be made. Final pricing and exact launch dates are still unknown, but the limited quantity guarantees a very high cost.
