The Seasonic Prime TX-1600 flagship receives the Noctua treatment in this updated edition. The collaboration brings a bespoke NF-A12x25 120 mm fan and custom grille, replacing the original 135 mm unit to cut noise by a claimed 8–10 dB and earn a Cybenetics LAMBDA A++ acoustic rating.

Compliance moves forward to ATX 3.1 and PCIe 5.1. The unit now ships with the newer 12V-2x6 connector instead of the earlier 12VHPWR design and can absorb a 3200 W transient spike without tripping protection or significant voltage drop—a key improvement over the original model's 2000 W limit.

Electrical performance remains top-tier: a single 12 V rail delivers 133.3 A, 80 Plus Titanium efficiency is maintained, and the fully modular design persists. Dimensions measure 210 × 150 × 86 mm at 3.2 kg. Protection features include OCP, OPP, OTP, OVP, SCP, and UVP, backed by a 12-year warranty.
