Seasonic Prime TX-1600 1600W, ATX 2.4

Seasonic hat seine Flaggschiff-Reihe PRIME Titanium um zwei weitere Modelle mit 1.300 W und 1.600 W erweitert, welche zwar noch nicht offiziell den neuen ATX-3.0-Standard unterstützen, aber schon zwei der neuen 12VHPWR-Stecker für Grafikkarten mitbringen. Wir haben Seasonics neues Spitzenmodell mit 1.600 W einem ausführlichen Test unterzogen.

Seasonic’s flagship Prime Titanium unit can meet the mighty Corsair AX1600i eye-to-eye in terms of overall performance with 115V input. If they tune the PFC converter for higher PF with 230V, among some other changes, this will be feasible with 230V input, too. The TX-1600 shows that analog controllers still have life in them and that they can offer similar performance to digital implementations. That said, I would like to see Seasonic following the totem-pole PFC route, which is the only way as it seems for a Cybemetics Diamond-rated efficiency PSU. I am also expecting an updated version of this platform, able to meet the ATX 3.0 spec’s requirements fully and not only up to 1000W. Nobody can be sure whether the new GPUs will have high power spikes, requiring the PSU to be able to go up to 200% of its max-rated capacity. Still, considering that you invest in a high-end PSU, having in mind that you will keep it for at least 5-6 years, it is nice to be as future-proof as possible. On the other hand, Seasonic built this PSU with the ATX 2.53 spec in mind and not ATX 3.0, so the compatibility with the latter, even up to 1000W, is an added extra for this product. The 450W that the TX-1600 can deliver through a 12VHPWR will be probably enough to cover your needs with all RTX4000 cards but the Ti ones, for which nobody has a clue yet.
