ASUS ROG Strix 850W Gold ATX3.0 vs NZXT E850: Comparison
ASUS ROG Strix 850W Gold ATX3.0 vs NZXT E850 fan size compared
They are built to different briefs, and fan size shows it, ASUS ROG Strix 850W Gold ATX3.0 135 mm against NZXT E850 120 mm.

Who each one is for
Buy the ASUS ROG Strix 850W Gold ATX3.0 for anyone who wants fully modular cabling with native 12V-2x6 support and systems where a 10-year warranty and Gold-tier efficiency matter, though it is the wrong buy for builds needing more than 850W of continuous headroom and buyers who need the smallest possible SFX/SFX-L footprint. The same goes for builders targeting a popular RTX 4070 Ti / RTX 5070-class gaming build. 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 built for anyone not using NZXT CAM software and extreme multi-GPU workstation loads above 850W.

Verdict
ASUS ROG Strix 850W Gold ATX3.0
8.3 / 10 Expert Rating
A solid 850W Gold-rated ATX unit for a popular RTX 4070 Ti / RTX 5070-class gaming build, held back only by the usual mid-tier compromises on cabling and OEM sourcing.
NZXT E850
8.5 / 10 Expert Rating
A Seasonic-grade platform with genuinely useful CAM telemetry, worth the premium for NZXT ecosystem builds.
