AMD recommends a 750W power supply for the RX 7900 XT. Most partner cards use two PCIe 8-pin plugs, so check that the unit lists enough 8-pin cables.

We compared wattage, connectors and ratings from the power supply listings against the card maker's guidance; we did not load-test these units.

How We Chose

Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

A 24-pin ATX power cable held in a hand
The figures behind the order
We lined up six power supplies on rated output, native 12V-2x6 cable count, 8-pin PCIe connector count and warranty from manufacturer specifications. We did not test them in-house, and 8-pin PCIe connector count and warranty are missing for at least one pick.
The shared baseline
All 6, from the be quiet! Pure Power 13 M 750W to the darkFlash DG750, state rated output, native 12V-2x6 cable count and 80 Plus rating and share Gold 80 Plus rating and Black colour.
Where the specs have gaps
The ASRock Phantom Gaming PG-750G, the MSI MAG A750GL PCIE5, the Rosewill VMG 850W and the darkFlash DG750 give no 8-pin PCIe connector count; the be quiet! Pure Power 13 M 750W and the be quiet! Pure Power 12 750W give no warranty.
Price range
From the darkFlash DG750 to the MSI MAG A750GL PCIE5, all sat in the $50 to $100 tier when we checked.

What to Look for in a PSUs for RX 7900 XT

  1. Rated output across these picks

    Here rated output runs from 750W on the darkFlash DG750 to 850W on the Rosewill VMG 850W, a 13% spread. The Rosewill VMG 850W is the pick for rated output.

  2. Warranty

    The ASRock Phantom Gaming PG-750G tops warranty at 10 years and the darkFlash DG750 sits lowest at 5 years; 2 picks share the top figure.

  3. 8-pin PCIe connector count

    Across these 2 picks 8-pin PCIe connector count spans 3 (the be quiet! Pure Power 12 750W) to 4 (the be quiet! Pure Power 13 M 750W). If 8-pin PCIe connector count is your first filter, the be quiet! Pure Power 13 M 750W sets the ceiling at 4. The ASRock Phantom Gaming PG-750G, the MSI MAG A750GL PCIE5, the Rosewill VMG 850W and the darkFlash DG750 give no 8-pin PCIe connector count figure, so 2 of 6 picks are compared here.

  4. What to check at home

    The be quiet! Pure Power 13 M 750W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
