Seasonic's latest PSU, part of its Prime series lineup, sports a whopping 2200 watts of power capability. Dubbed the Prime PX-2200, it's naturally ATX 3.1 compatible, with four 12V-2x6 power cables—enough to power four top-end RTX 4090 graphics cards. U.S. pricing is unavailable (likely due to the 1,800-watt limit of standard U.S. power outlets), but European pricing is set at €579.90.
The PSU's 2200W rating makes it the most powerful unit in Seasonic's arsenal currently, featuring 37% more wattage headroom than its 1600W counterparts. The PX-2200 is 80 Plus platinum rated and fully supports the latest ATX 3.1 and PCIe 5.1 specifications, future-proofing the PSU to operate next-generation graphics cards. The monster PSU also comes with a lengthy 12-year warranty.
