Antec at the 2023 Computex showed off the NeoECO line of performance-segment PSUs that offer ATX 3.0 spec readiness, and native 600 W 12VHPWR connectors. The series comes in 850 W, 1000 W, and 1300 W variants, each with full modular cabling, and a segment-best 10-year warranty. These feature a single +12 V rail design with 80 Plus Gold switching efficiency, active PFC, DC-to-DC switching, and most common electrical protections. All three models are 14 cm long (even the 1300 W), and use 120 mm FDB fans to keep cool. All three models offer one 12VHPWR connector, two 4+4 pin EPS, and while the 850 W model gives you six 6+2 pin PCIe power, the others give you eight.
Antec is a little slow to release ATX 3.0 spec PSUs, but I guess it's better late than never.
