The best approach is to attempt overclocking your CPU and check if performance improves in benchmarks. I own a 5070Ti paired with a Ryzen 3600, and I’m finding it necessary to push the overclock to near its limit just to keep my card from being the limiting factor, around 20%. There’s a bottleneck calculator available that can show you the exact percentage of bottlenecking.
You may notice a performance decrease particularly when using a PCI slot 4, as it changes your x16 to x8 configuration on that motherboard.
PE2 – x16 (Gen3, x16 lanes from CPU, x8 shared with PE4)
A minor reduction of 4 to 10 frames is expected when using PCI Gen 3 x16, which isn’t a major problem.
I strongly suggest using a higher quality adapter; the one included in the NVIDIA box is unreliable, especially if you handle it near the connector.
Avoid bending it too close to the connector—maintain at least 3.5cm clearance before any damage can happen. CableMod may differ from Seasonic, but mine has remained stable with no issues so far.

It's significantly more than just a short period in time.
The G2 1000w was introduced in 2012 and typically lasts only a couple of years before being discontinued, meaning a unit at this stage would be around 12 years old or older. The G3 1000w came out in 2016, so even if your model dates back to 2015, it would still be roughly 10-11 years old—considering the age of any power supply, which is hard to ignore regardless of brand or initial performance.
The first step you should take is swap it for a newer, reliable unit with at least 850w capacity. If you're pushing performance beyond normal limits, consider upgrading to a 1000w model; otherwise, 850w should suffice even when accounting for power spikes (transient surges). As long as it's an ATX 3.0 or 3.1 certified unit and comes from a reputable manufacturer, this is still a reasonable choice.
Another concern I have is the EVGA motherboard you're using. I've noticed many users report problems with these boards, such as unstable PCIe connections, inconsistent USB and fan operation, and erratic power management despite a confirmed "power good" status. With so much wear in that age range, it's unlikely your issues stem solely from the board itself—though it's worth considering.
