Verdict
ASUS ROG Strix 1000W Gold ATX3.0
8.2 / 10 Expert Rating
ASUS extends the Strix Gold ATX3.0 line to 1000W here, keeping the Aura Sync-lit fan shroud and Axial-tech blades from the 850W model while adding headroom for a higher-end GPU.
Cooler Master GX3 850W
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.
