I'm looking to use an RTX 4070 TI with my Corsair SF 450W power supply. Is there a way to reliably limit the GPU's power draw to stay within the PSU's capacity? For context, I'm running an AMD Ryzen 2700X, and while I typically undervolt for efficiency, I'm considering a hard power cap in this case. Any advice?

Yeah, it should work fine with a power cap. Just keep an eye on the performance since you're running on lower wattage.
You can actually lower the power limit of the 4070 TI to about 65% and still keep it running with a 450W PSU. Just know that long-term, you'd be better off upgrading your PSU for optimal performance.
It's definitely possible to limit the power, but I'm curious why you'd want to limit a nicer GPU like that. If you're not using it to its full potential, why go through the hassle?
Sure, you can cap it at around 50% to remain under the PSU's limit, but just a heads up – you'll experience a major drop in performance. The 4070 TI isn't that strong at lower limits without significant undervolting.
