my pc doesn't reach full performance even when using maximum settings
This configuration seems to result in significantly lower FPS compared to what I expect. For example, League of Legends averages around 120 FPS, while my GPU is only using 20-30% and my monitor is at 144Hz. My friend with a 1070 GPU on a 4K display achieves at least 200 FPS. It appears there might be insufficient power available from my PSU, as my GPU draws 650W but only 100W remains for the rest of the system. I've checked all NVIDIA settings and high performance options, left VSync disabled, enabled GSync, and removed GeForce Experience without any noticeable improvement. I'm also using an updated BIOS.
The issue isn't with your power supply. A 2070 suggests a 650W PSU, considering the rest of the setup—but that’s unrealistic for a standard graphics card cooler, which can’t reliably handle more than 300W. Those tips were based on older systems with less consistent power delivery, so they’re a bit excessive. I’d first look at the drivers and confirm XMP is active.
Your setup isn't delivering even a fraction of 750W during gaming, and the Vengeance remains a reliable choice. The 2070 Super doesn’t require 650W at all—most makers just suggest that. Fix your video drivers, download the newest ones from the GeForce site, and test both with G-Sync enabled and disabled.
Your in-game frame rates aren’t capped, it’s unclear what stress testing method works. Removing the G-Sync didn’t make a noticeable change, and even after updating drivers, performance stayed limited.
To check your GPU's power consumption, use GPU-Z and look under Advanced/Nvidia Bios for details. An RTX 2070 typically runs around 200 watts at maximum with overclocking. This value may change based on the chip and cooling solution. For a detailed view, run a benchmark such as Heaven with GPU-Z enabled to sensors, selecting Power Consumption (W). To monitor CPU power, use hwinfo64 under CPU power settings. A Cinebench R15 test will give you the peak power usage. Most 2080 Ti models exceed 300 watts and rely on standard coolers. My EVGA XC model with two fans and two slots uses up to 347 watts, while my FTW3 Ultra reaches about 387 watts. The same cooling setup applies to 2070s. What bothers most about the 2080 Ti is its power limits are tied to its cooling system. In contrast, my GTX 1080 was constrained by its clock speeds.
