Antec Signature 1300 Platinum vs Corsair AX1600i: which one fits your build
The Antec Signature 1300 Platinum suits builders targeting a workstation or multi-GPU build with serious headroom and anyone who wants fully modular cabling with native 12V-2x6 support, though it is the wrong buy for builds needing more than 1300W of continuous headroom and buyers who need the smallest possible SFX/SFX-L footprint.

It is not the one for anyone wanting a native ATX 3.1 12V-2x6 cable out of the box.

Verdict
Antec Signature 1300 Platinum
8.8 / 10 Expert Rating
A best-in-class 1300W Platinum-rated ATX unit for a workstation or multi-GPU build with serious headroom, held back only by its premium price.
Corsair AX1600i
9 / 10 Expert Rating
Still the digital-monitoring benchmark for extreme multi-GPU and workstation builds, docked slightly for lacking a native 12V-2x6 connector.
