1200 W, even for a short period of time, is crazy for a desktop computer.
I have an i9-9900K and an RTX 3080. My computer is also plugged into a Kill-a-watt to measure its power usage.
I ran Prime95's CPU torture test using the max power option while also crypto-mining on the GPU. I peaked at 650 watts for a couple seconds until the CPU began thermal throttling.
If I can't hit 700 watts while trying to use as much energy as possible, I can't imagine what monster system would even touch 1000 watts, assuming we're still talking consumer-grade.
Counting my monitors and the small network switch on my desk, I can hit around 750-800 watts sustained with a 5950X and a 3090 running compute intensive workloads as measured at the wall by a power meter.
So yeah, there's plenty of head space but I have also hit circuit breaker issues recently on a proper (non consumer) workstation so the limit is fresh in my mind.
