Silverstone claims this unit to be the first ATX 3.0 unit, which is somewhat true. Silverstone is the first on the market to release an ATX 3.0 compatible unit with official marketing around it, but Corsair’s HXi 2022 series came out just before it, so far passing in-house testing for the requirements of ATX 3.0. There were also a few other ATX 3.0 units that were announced before the Hela 850R, but these are still yet to be released. I expect Cybenetics to have done the verification for Silverstone, as Intel is yet to officially verify units for ATX 3.0.
