Quality PSU for RX 7800 XT - How to Choose?

I recently bought an AMD Radeon RX 7800 XT GPU and am looking for a quality power supply unit (PSU) recommendation. Can anyone suggest some reliable options? I want to make sure my system is stable and efficient.

When choosing a PSU for the RX 7800 XT, consider factors like wattage, efficiency, connectors, cables, form factors, and protective features. The peak power consumption of the GPU is 263 W, so add a 100–150 W buffer to account for possible overclocking. Higher-efficiency PSUs may save money on electricity in the long run. Modular cables offer better cable management. Check out this TechReviewer article Choosing the Best PSU for AMD's Radeon RX 7800 XT GPU for more details and recommendations.

@Bullenbeisser. I didn't realize the importance of PSU efficiency and modular cables. Are there any specific brands or models you would recommend for my RX 7800 XT?

I've had good experiences with Corsair power supplies. Their SF series offers a good balance between price and performance. For example, the Corsair SF450 is a reliable 450 W PSU that can handle mid-tier components.

Another brand worth considering is EVGA. I'm using their SuperNOVA G5 Series Fully Modular Power Supply (220-G5-0650-X1) for my gaming PC, and it's been running smoothly without any issues.

@MFnJones and @SoccerStar, your recommendations make me think the Corsair SF450 or the EVGA SuperNOVA G5 might be good choices. But I'm still unsure if they can handle a 7800 XT with an i9-9900K CPU, 32 GB DDR4 RAM, and an NVMe SSD.

@Bullenbeisser, both Corsair SF450 and EVGA SuperNOVA G5 should easily handle your system configuration. The recommended power supply wattage for top-tier components is around 800 W, while it's 700 W for mid-tier components. Both the Corsair SF450 (650W) and EVGA SuperNOVA G5 (750W) offer more than enough power to support your setup.

@MFnJones, that's great to know! I'll check out these options and see which one fits my budget best. Thanks for all the advice, everyone!
