In the used market, the Radeon RX 6400 fails to justify its value for money. It lags behind the GeForce RTX 2070 what outpeforms it by a lead of 152.0% in 3DMark benchmark.
The Radeon RX 6400 requires 53 watts to operate. However, when selecting a power supply, it's crucial to account for the power consumption of the entire system. Therefore, add together the TDP of your GPU and CPU, then multiply the sum by 2. For instance, if you pair Radeon RX 6400 with Intel Core i3-12100F, which has a TDP of 60W, you should aim for a power supply around 400 watts. This approach ensures a substantial margin, allowing your PSU to operate coolly and efficiently.
Another reason to opt for a more potent PSU than your system's exact power requirement is due to GPU transient power spikes, which occur when the GPU is under heavy load. These spikes may cause the PC to shut down if the PSU lacks sufficient overhead. For overclocking or future-proofing, you might even want to consider an even more powerful power supply, as the trend in current GPU power requirements seems to be increasing year by year.
While it may be tempting to choose cheaper brands with similar ratings and specifications on paper compared to more expensive brands, it's always advisable to invest in a reputable brand like Cooler Master, EVGA, or Corsair. Compromising your entire system to save a few dollars is not worth the risk. A faulty PSU can damage your entire system, and in the worst-case scenario, it can even cause a fire hazard.
