We're on the ground at IFA 2026 in Berlin, where the Chieftec display featured two new power supplies: the Titan ATX (TTP-1650 FC) and the Duplex (RTX-1000 G). The Titan is the bigger of the two, rated at 1650 W with an 80 Plus Titanium certification, putting it among the more efficient units Chieftec has built. It's fully modular and comes dressed in soft, textured cabling rather than the flat ribbon style seen on older Chieftec units. It uses the ATX 3.1 standard, is compatible with PCIe Gen 5, and features a 135 mm FDB fan.

The Duplex takes a different approach. It's a 1+1 redundant ATX PSU rated at 1000 W per module with 80 Plus Gold certification, aimed at workstation and server builds where uptime matters more than raw wattage. Cabling here is non-modular, likely to keep the unit's footprint as compact as possible, with individual wires gathered into small bundles rather than a flat cable design. Chieftec hasn't shared pricing or availability for either PSU yet, but we will definitely know more soon enough.

The Titan slots in above Chieftec's existing high-wattage units, while the Duplex fills a role Chieftec hasn't really addressed before with a proper dual-module redundant design at this wattage.
