In the rapidly evolving world of gaming and high-performance computing, a new standard is being set by enthusiasts and professionals. Recently, a user on Reddit, known for their ambitious tech projects, has demonstrated the remarkable capabilities of modern power supplies. They successfully assembled a PC incorporating not one, but four GeForce RTX 5090 graphics cards, showcasing an unprecedented level of computing power and energy demand.

Technical Feat: Fitting the Giants
Accommodating four massive RTX 5090 cards is no small feat. The custom PC builder opted for an exceptionally large case, specifically designed to separate the graphics card compartment from the rest of the components. The chosen cards, Asus Astral models, each occupy four expansion slots, demanding a case that is twice as wide as usual. This approach not only optimizes space but also aids in effective cooling and airflow management-critical for such intensive hardware setups.
Power Requirements and Challenges
The power requirements for this assembly are staggering. To support the factory-overclocked RTX 5090s alone, approximately 2200-2400 watts of power is required. To ensure stability and headroom for future upgrades or additional peripherals, the builder has employed two separate 2400-watt power supplies.

Potential Electrical Limitations
One might contemplate the electric capacity needed for such an intense setup. In many regions, home electrical systems are designed to handle about 15-20 amps. In Europe, with a voltage of 230V, the total energy consumption of this powerhouse, under full load at approximately 3000 watts, equates to around 13 amps. While this is below the threshold, simultaneous use with other household devices could easily trip circuit breakers, suggesting that users tread carefully with additional devices.
Impact on the Gaming and Tech Landscape
This development speaks volumes about the growing capabilities and demands of the gaming industry and high-performance computing markets. Enthusiasts and professionals alike are pushing the boundaries, signaling a shift towards more energy-intensive and powerful computer systems. Such setups are not only pivotal for gaming but for complex simulations, deep learning, and graphical rendering tasks, areas where time and precision are essential.
The Road Ahead
As technology and energy converging solutions continue to evolve, it will be fascinating to see how the industry adapts. Companies may soon focus more on energy efficiency and innovative cooling techniques to support these burgeoning demands. This Reddit user’s ambitious project is a window into the future of computing-a future where extreme performance meets the realities of energy consumption.
