They offer several models from ChiefTech Power Supply, though some are considered mediocre. A few appear on the Avoid section of their PSU rankings. If you're using one of these and it's underperforming, your graphics card may not receive sufficient power.
The model falls into Tier C (Low End). It’s possible this could be the cause. If I were you, I’d verify the software first—check drivers and updates, use the motherboard manufacturer’s site for BIOS and all Windows updates—but since the PSU seems to be the issue now that we know it’s a low-quality unit and relatively old, replacing it might be best unless you test your sister’s PSU in the system.
You've noticed some interesting behavior with your setup. It seems the system performs well under full load but shows instability in lower power conditions. That could be due to the power supply struggling with reduced wattage. Testing with a different PSU might help clarify the issue. I'll keep an eye on this and share updates soon. Thanks for your feedback!
The 7700 with DDR5 appears less powerful compared to the 5700 using DDR4 because it lacks the higher performance features of DDR5. Adjust your Task Manager view to show Logical Cores so you can spot a single core operating at full capacity, causing performance issues.
lowest performance build is 5600 with a 6600 graphics card, yet it's outperforming you in FPS
I checked using a solid 850W power supply, but there was no difference, so it’s probably not the PSU. It could be the motherboard, RAM, or CPU.
