Who each one is for
Buy the Antec Signature 1300 Platinum for 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 not built for builds needing more than 1300W of continuous headroom and buyers who need the smallest possible SFX/SFX-L footprint. The NZXT E850 is the one to take for NZXT CAM ecosystem builds and high-end single-GPU rigs wanting live power telemetry, though it is not the pick for anyone not using NZXT CAM software and extreme multi-GPU workstation loads above 850W. Our rating of the Antec Signature 1300 Platinum (8.8/10): 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. Our rating of the NZXT E850 (8.5/10): A Seasonic-grade platform with genuinely useful CAM telemetry, worth the premium for NZXT ecosystem builds.
