AMD recommends 650W for the RX 9070, so 750W to 850W leaves headroom for a hungry processor. Every pick is an ATX unit of 750W to 850W with at least two 8-pin PCIe connectors, ordered by warranty length.
Rankings weigh wattage, native 12V-2x6 cables and PCIe 8-pin connectors as the makers state them; if a maker skips cybenetics rating, the guide says so rather than guess, since we have not benched them.
