Question 750 Watt PSU for 7900XT

[tm1912]

Hello, I just bought an ASROCK 7900XT Phantom Gaming OC card a day ago and saw that the recommended power supply was 750 Watts. I have a Seasonic Focus-PX 750W that I bought fairly recently (December 2021) and don't really want to spend more money for a new power supply when this one is good, just not enough wattage potentially. My CPU is a Ryzen 7 5800x, so that will be paired with the 7900XT, which makes me not sure if my power supply is enough. Any thoughts?

Also, I usually run most of my stuff stock, so no overclocking will be done as well.

That card only has a 300w TDP, the 750W recommendation is to give sufficient headroom for the rest of the system, and to account for lower quality units.
I see no reason to replace your PSU.

Thank you, I was thinking my power supply seemed good enough for it, but sometimes my pc would crash depending on the game. For example, when I first played Spider-Man remastered when it came out, my pc would crash 15-20 minutes into it and this is before the upgrade to a 7900XT as well. I have a 2060 right now, so should I just RMA the power supply with Seasonic?

Well, that could require further testing (temps under load, game tests, etc) start another thread for that, youll get more help.
Assuming it is the PSU, the crashes arent a result of it not having enough wattage.

If the power supply is not big enough an RMA won't help.

I would upgrade always want to have some buffer with your power supply.
