    Recommended For

    • Builders pairing a high-end graphics card, including an RTX 50-series card, with a gaming or streaming system who want a native 12V-2x6 connection rather than relying on a separate adapter.
    • People building a powerful desktop for gaming, streaming, or AI workloads who need a 1000W ATX 3.1 supply with a native 600W-capable 12V-2x6 connector.
    • Quiet-conscious builders whose PC spends most of its time at low or moderate power draw; independent testing found low noise at those loads, though fan noise rises as load increases.
    • ATX case builders with limited PSU depth who want fully modular cabling; the unit is 150 mm deep, and its modular design lets them connect only the cables their build needs.
