The video explores testing SFX power supplies (ranging from 450 to 750 watts) to run the power-hungry RTX 3080 GPU. It delves into the importance of considering CPU and GPU power consumption, especially with high-core-count CPUs like the Intel 10900k. Results show that 600W PSUs can handle systems with CPUs like Ryzen 5 and Ryzen 7, with undervolting the RTX 3080 offering some power savings. While a 600W PSU suffices, higher output PSUs are recommended for quieter operation and peace of mind, despite surprises in testing like the 750W Corsair SF750 and the 650W NZXT H1 PSUs running smoothly with overclocked setups.

In this segment of the video, the content creator is testing various SFX power supplies ranging from 450 to 750 watts to see if they can effectively run the RTX 3080 GPU, which is known for its high power consumption. The official recommendation for the RTX 3080 is a 750 watt power supply, but the question is raised if a 600 watt power supply could suffice. The video highlights the importance of considering both the GPU and CPU power consumption when choosing a power supply. The content creator discusses various power supply models, including Corsair SF450, SF600 (80 plus gold and platinum), SF750, and the 650 watt pre-installed power supply in the NZXT H1. The video emphasizes that the CPU’s power consumption, especially with high-core-count CPUs like the Intel 10900k, can also significantly impact the power supply requirements when paired with the RTX 3080. Further testing is conducted to determine which power supplies can handle the demands of the RTX 3080 under varying loads.

In this segment of the video, the focus is on power consumption during gaming with specific attention to the CPU and GPU power draw. The CPU power usage varies across different games, with Battlefield 5 showing the highest power draw due to its CPU intensity. Lowering the resolution from 4k to 1440p increases CPU utilization significantly. When running the system at stock settings, the power draw during gaming can be reduced by 20 to 30 watts. Testing different power supplies with the RTX 3080 and an overclocked 10900k revealed surprises – the 750W Corsair SF750 and 650W NZXT H1 power supplies ran without issues, while the 600W Corsair SF-600 units managed to support the high power consumption without tripping, but the 450W SF450 struggled to load games under the same conditions.

In this segment of the video, it was found that a 600-watt power supply is sufficient for running systems with CPUs like Ryzen 5 and Ryzen 7, which are typically in the 100 to 150-watt range. Undervolting the RTX 3080 may not significantly reduce power consumption due to the high clock speeds of the GPU. However, lowering the voltage on the RTX 3080 could save around 30 watts in power consumption. It was noted that for those with a decent quality 600-watt power supply, there is no urgent need to upgrade to a higher output unit when considering the RTX 3080. However, higher output units are still recommended for quieter operation and peace of mind, especially when building new systems.
