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.
Seasonic Vertex PX-1000
8.7 / 10 Expert Rating
Vertex PX steps up from the Gold-rated Vertex GX line to Platinum efficiency at 1000W, giving Seasonic a mid-tier option between the mainstream Focus series and the Prime flagships.
