How many Nvidia GeForce RTX 5090’s can you power off a single power supply? Well, if you own this brand-new Silverstone PSU, the answer is three. Wildly impractical as it might be for most gamers, the new Silverstone Hela 2500Rz has four 12V-2x6 power connectors for RTX 40 and 50-series GPUs, letting you power three RTX 5090s or four RTX 4090s from a single 2,500W power supply.
Most gaming rigs with even the best power supplies are pushed hard by one top-spec Nvidia graphics card, let alone three or four. While a 2,500W PSU isn’t a requirement for building the best gaming PC, if you’re planning a more specialist PC build where gaming isn’t necessarily the focus, a Silverstone power supply like this one could do the job.
