Above 1000W, fully modular cables keep the case manageable. Every pick is fully modular and 1000W or more, ordered from the lowest price.
Rankings weigh wattage, native 12V-2x6 cables and PCIe 8-pin connectors as the makers state them; we did not test these power supplies ourselves, and if a maker skips native 12V-2x6 cables, the guide says so.
