Verdict

Antec Signature 1300 Platinum

8.8 / 10 Expert Rating

A best-in-class 1300W Platinum-rated ATX unit for a workstation or multi-GPU build with serious headroom, held back only by its premium price.

Corsair RM750x

8.3 / 10 Expert Rating

A solid 750W 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.
