    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.

    Thermaltake Smart BX3 650W

    7.3 / 10 Expert Rating

    One of the most affordable routes to a native 12V-2x6 connector, at the cost of Gold-tier efficiency and acoustics.
