Asked by GamerDude93
I'm looking to upgrade my PC and I'm wondering about my power supply. I know that the recommended wattage for the graphics card is 850W, but I currently have an 800W PSU. My CPU is the 7800X3D. Do you think 800W will be sufficient for my setup?

What's the brand of your PSU? That's a key factor. If it's a reliable one like Silverstone, you're probably good. If it's something lower tier, like a Thermaltake TR2, you might want to reconsider it.

HonestOpinion99: Absolutely! The brand can make a huge difference. A decent Cougar PSU can hold up well even at 800W!

You should be fine with an 800W PSU, as long as it's a good quality one! It should handle your setup without any issues.
