GUIDE
Is 750W enough for an RX 9070 XT?
Yes, for most gaming builds. Go 850W for an Intel K-series or Core Ultra 7, or a Ryzen 9, and check your card's rating first: factory-overclocked models need a little more.
AMD's minimum for the RX 9070 XT is 750W, and the card is rated at 304W typical board power. AMD didn't sell its own version of this card, so every 9070 XT is a partner design from Sapphire, PowerColor, XFX, ASRock and others, and the factory-overclocked ones are often rated higher.
The math for common pairings
These use the same method as the calculator: card power + the CPU's stock power limit + 150W for the rest of the system, then 20% headroom, rounded up to a real PSU size. The second column is for factory-overclocked models like the PowerColor Red Devil, which is rated at 330W.
| CPU | CPU power | 304W card | 330W card |
|---|---|---|---|
| Ryzen 5 7600 | 88W | 650W | 750W |
| Ryzen 5 9600X | 88W | 650W | 750W |
| Core i5-12400F | 117W | 750W | 750W |
| Ryzen 7 7800X3D | 162W | 750W | 850W |
| Ryzen 7 9800X3D | 162W | 750W | 850W |
| Core i5-14600K | 181W | 850W | 850W |
| Ryzen 9 9950X | 200W | 850W | 850W |
| Core Ultra 7 265K | 250W | 850W | 1000W |
| Core i7-14700K | 253W | 850W | 1000W |
| Core i9-14900K | 253W | 850W | 1000W |
A stock-rated card with a 6-core Ryzen lands exactly on 650W. That works on paper, but it's below AMD's own minimum and leaves nothing spare, so 750W is the better buy unless you're reusing a good 650W unit you already own.
Why factory-overclocked cards change the answer
The 304W figure is AMD's spec. Partner cards with bigger coolers and higher clocks raise the power limit, and the card will use it. An extra 26W doesn't sound like much, but it's enough to push an X3D Ryzen build from 750W to 850W, and a Core i7/i9 K-series or Core Ultra 7 build from 850W to 1000W.
Check the board power on your exact model's spec page. If it's above 304W, add the difference before you use the table, or pick the card in the calculator and size up one step if you land close to a line.
Which power plugs your card uses
AMD's spec calls for two 8-pin PCIe plugs, and most 9070 XT cards use exactly that. Two common exceptions:
- Three 8-pin plugs on some factory-overclocked cards, like the PowerColor Red Devil. You need three separate PCIe cables from the power supply.
- One 16-pin 12V-2x6 plug on a few models, including the Sapphire Nitro+ and ASRock Taichi. Use a native 16-pin cable from an ATX 3.0 or 3.1 power supply, or an adapter if your card comes with one. See 12VHPWR vs 12V-2x6 for how to seat it properly.
Before you buy, count the separate PCIe cables on your PSU, not the plugs. How to check what connectors your PSU has walks through it.
What about the regular RX 9070?
The non-XT RX 9070 is rated at 220W, AMD's minimum is 650W, and it also uses two 8-pin plugs. With the same math, 550W is enough with a Ryzen 5, 650W covers an X3D Ryzen or a non-K Core i5, and 750W covers K-series Intel chips, the Core Ultra 7 and the Ryzen 9 9950X.
