Which should you buy, ASUS ROG Strix 850W Gold ATX3.0 or Silverstone ST75F-PT?
The ASUS ROG Strix 850W Gold ATX3.0 is the one to take 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.

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.
