Which should you buy, ASUS ROG Strix 850W Gold ATX3.0 or Corsair SF750?
The ASUS ROG Strix 850W Gold ATX3.0 suits 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 not the pick 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. Buy the Corsair SF750 for builders targeting a small-form-factor build running a high-end GPU and anyone who wants fully modular cabling with standard PCIe connectors, though it is the wrong buy for builds needing more than 750W of continuous headroom and buyers who need a full-size ATX chassis.
