The Best Power Supplies for the RX 7900 XTX
Six 850W to 1000W units for the RX 7900 XTX, which AMD pairs with 800W, compared on 8-pin connectors and efficiency.
By Alex Morgan, PC Hardware Editor
12 min read6 products evaluated
AMD recommends an 800W power supply for the RX 7900 XTX. Partner cards use two or three PCIe 8-pin plugs rather than a 16-pin connector, so count the 8-pin cables on the unit.
We compared wattage, connectors and ratings from the power supply listings against the card maker's guidance; we did not load-test these units.

Best Match for an RX 7900 XTX1 of 6
be quiet! Pure Power 13 M 1000W
be quiet!'s Pure Power 13 M 1000W offers four PCIe 8-pin connectors plus a native 12V-2x6, and Cybenetics rates it Platinum.
Best for
- Triple 8-pin partner cards.
Skip if
- Pass if a published warranty matters; this one has none.
Why we like it
The fan stops at low load. Its fan stops completely at low load, and LLC topology gives tight voltage regulation for a quiet system. It matches the FSP Hydro Ti Pro 1000W and the MSI MPG A1000GS PCIE5 II on rated output (1000W).
It matches the FSP Hydro Ti Pro 1000W, the be quiet! Power Zone 2 850W, the Thermaltake Toughpower GT 850W and the Super Flower Leadex VIII Platinum PRO 850W on native 12V-2x6 cable count (1). Its 4 8-pin PCIe connector count ranks second of 4 here, behind the FSP Hydro Ti Pro 1000W (5) and ahead of the MSI MPG A1000GS PCIE5 II (3). Like the MSI MPG A1000GS PCIE5 II and Thermaltake Toughpower GT 850W, it has a gold 80 plus rating, while the FSP Hydro Ti Pro 1000W uses a titanium 80 plus rating. You also get semi-passive cooling at low load.

Most 8-Pin Connectors2 of 6
FSP Hydro Ti Pro 1000W
FSP's Hydro Ti Pro carries an 80 Plus Titanium rating, five PCIe 8-pin connectors plus a 12V-2x6 cable, and a 10-year warranty.
Best for
- Premium builds.
Skip if
- Price-first buyers should look at the Thermaltake Toughpower GT 850W, which cost less when we checked.
Why we like it
It is 150mm deep and holds a Cybenetics LAMBDA A++ noise rating. On rated output it ties with the be quiet! Pure Power 13 M 1000W and the MSI MPG A1000GS PCIE5 II at 1000W. On native 12V-2x6 cable count it ties with the be quiet! Pure Power 13 M 1000W, the be quiet! Power Zone 2 850W, the Thermaltake Toughpower GT 850W and the Super Flower Leadex VIII Platinum PRO 850W at 1.
Nothing else here matches its 5 8-pin PCIe connector count; the be quiet! Pure Power 13 M 1000W comes closest at 4. You get a titanium 80 plus rating here, which sets it apart from the Thermaltake Toughpower GT 850W and its a gold 80 plus rating. It was the highest-priced of the 6 picks at the time of writing, so the case for it rests on what it adds over the be quiet! Pure Power 13 M 1000W and the rest.

Best for a Later NVIDIA Card4 of 6
MSI MPG A1000GS PCIE5 II
MSI's MPG A1000GS PCIE5 II is the only 1000W unit here with two native 12V-2x6 cables, and it adds three PCIe 8-pin connectors.
Best for
- Switching GPU makers later.

Best Value 850W5 of 6
Thermaltake Toughpower GT 850W
Thermaltake's Toughpower GT 850W is a fully modular ATX 3.1 unit with a native 12V-2x6 cable, a single high-amperage 12V rail and a Smart Zero Fan mode.
Best for

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.
- The figures behind the order
- We set side by side six power supplies on rated output, native 12V-2x6 cable count, 8-pin PCIe connector count and warranty as the makers state them. Nothing was tested in-house; 5 of the 13 fields compared are stated for every pick, while 8-pin PCIe connector count and warranty have gaps.
- The shared baseline
- All 6, from the be quiet! Pure Power 13 M 1000W to the Super Flower Leadex VIII Platinum PRO 850W, state rated output, native 12V-2x6 cable count and ATX version and share ATX 3.1 ATX version and Black colour.
- Where the specs have gaps
- The Thermaltake Toughpower GT 850W and the Super Flower Leadex VIII Platinum PRO 850W give no 8-pin PCIe connector count; the be quiet! Pure Power 13 M 1000W, the be quiet! Power Zone 2 850W and the Super Flower Leadex VIII Platinum PRO 850W give no warranty.
- Price range
- At our last check the picks ran from the Thermaltake Toughpower GT 850W ($50 to $100) to the FSP Hydro Ti Pro 1000W ($250 to $500).
What to Look for in a PSUs for RX 7900 XTX
Key buying criteria so you get the right fit the first time.
Rated output across these picks
Across these 6 picks rated output spans 850W (the Super Flower Leadex VIII Platinum PRO 850W) to 1000W (the be quiet! Pure Power 13 M 1000W). The be quiet! Pure Power 13 M 1000W is the pick for rated output.
Native 12V-2x6 cable count
Here native 12V-2x6 cable count runs from 1 on the Super Flower Leadex VIII Platinum PRO 850W to 2 on the MSI MPG A1000GS PCIE5 II, a 100% spread. If native 12V-2x6 cable count is your first filter, the MSI MPG A1000GS PCIE5 II sets the ceiling at 2.
Modular cable sockets on the back of a power supply 8-pin PCIe connector count
The FSP Hydro Ti Pro 1000W tops 8-pin PCIe connector count at 5 and the MSI MPG A1000GS PCIE5 II sits lowest at 3. For less, the be quiet! Pure Power 13 M 1000W is the runner-up at 4 ($100 to $150 tier). The Thermaltake Toughpower GT 850W and the Super Flower Leadex VIII Platinum PRO 850W give no 8-pin PCIe connector count figure, so 4 of 6 picks are compared here.
Cybenetics rating
The be quiet! Pure Power 13 M 1000W, the be quiet! Power Zone 2 850W and the Super Flower Leadex VIII Platinum PRO 850W list platinum; the FSP Hydro Ti Pro 1000W lists titanium. Settling cybenetics rating first narrows 4 picks to 3 or 1.
Power cables routed to a graphics card inside a PC What to check at home
The be quiet! Pure Power 13 M 1000W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter.
