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 AX1600i

9 / 10 Expert Rating

Still the digital-monitoring benchmark for extreme multi-GPU and workstation builds, docked slightly for lacking a native 12V-2x6 connector.
