My power supply is 750 Watt.
That is the advertised wattage of the unit. You will need to state the make and model of the unit. If you have a badly built unit, it can have a sticker on it saying 1000W but in reality it can output half of that number effectively. As a thumb rule, you're advised to have a PSU that has more wattage than the entire system will pull when taxed(under load).

Got a link to the card you purchased? If your card is an AIB variant which is akin to the Powercolor Red Devil's, you will need a higher wattage unit as the cards are factory overclocked.

Hello dogizmo. I agree with Lutfij, that your power supply mfg and model is needed. In addition, I recommend that you list all your system specs. With that said, the fact that the crashes stopped once you turned off XMP, makes me assume that the crashes are related to your memory somehow. Is your BIOS updated to the latest version? Do you have the chipset updated (amd) or management engine updated (intel). Important: Are your RAM chips installed in the slots that your motherboard's manual specifies? I once had an AMD B350 chipset motherboard which had two 16GB 2400 MHz RAM installed, running at 2133 MT with XMP off. Once I enabled XMP, the computer was completely unstable, and practically unuseable. I then realized that my RAM was in the wrong slots, but hadn't been a problem until I enabled XMP. At a minimum, I would update the BIOS, while adhering to the notes listed in the BIOS page. And then I would locate the manual and verify that the RAM was in the proper slots before re-enabling XMP. That's what I would do in your situation.
Thank you for both of your answers. I will share my specs;

My rams are kingstom hyperx predator 3000 Mhz 2x8 . Right now they are working on 2400 Mhz. When i do 3000 Mhz with new graphic card, sometimes i got crash and i need to unplug the power cable to open my computer again.( I know what is the correct position for ram slots. Before my new graphic card they were stable 2 years. )

"AMD's Radeon RX 7900 XTX, while a powerful GPU in its own right, is not overly demanding when it comes to power consumption. The TBP of the card has been set to 355 watts, which is nearly 100W less than Nvidia's RTX 4090"
355 watts is quite a bit of power draw. I'd suggest a new good quality 850 watt psu at a minimum.

It's very cheaply made and it's so old that Everest PSUs were trimmed off the list post-Tom's.
This PSU should not ever be even turned on with this GPU.

Yes, i am thinking the same but I am using this for almost 5,5 years. It doesn't make any problem. I ordered this today. MSI MPG A850GF 850W 80 PLUS GOLD

Cheap chinese brand. I would trash that one and get something on the Teir A list. Such and 2021 RMX 850 watt.
Never use a super cheap power supply with a good video card.

That's not how it works. A PSU doesn't just not cause any problems by not blowing up. Junk PSUs also slowly damage components over time, like someone who eats a pound of bacon for breakfast ever morning. The lifespan of anything this has ever been used with may have already been shortened, frequently considerably.
The only way you can show a PSU hasn't caused any issues is with an oscilloscope and load tester.
