MSI's RTX 5090 Lightning Z: Extreme Power Unleashed

MSI has unveiled the GeForce RTX 5090 32G Lightning Z, a statement piece designed to explore the extreme limits of flagship GPUs. This card features an extraordinary 40 power phases and a custom liquid cooling system with a triple-fan radiator, significantly increasing flow rate and liquid pressure. The robust design aims to provide exceptional speed, stability, and overclocking headroom.

The Lightning Z pushes power delivery to new heights, capable of drawing up to 1,000 watts, a first for a single GPU. This extreme power draw necessitates a high-end 1,600-watt or greater power supply with two native 12VHPWR connectors. For those seeking record-breaking performance, MSI has consulted elite overclockers and offers a "2,500W XOC BIOS" mode, though this voids the warranty.

Further distinguishing the card is its physical design, highlighted by an 8-inch LCD panel covering the front face, intended for vertical mounting. MSI has also announced that this is a limited edition, with only 1,300 units produced worldwide. The card is set to launch in February 2026, and while pricing is undisclosed, it is expected to be significantly expensive and sell out quickly.
