It'll actually probably be more than 180W given that AMD is lowballing their Ryzen 7 TDPs. Those chips are more in the 120-130W range under a typical (non-Prime95) load - so unless they drop the clocks on the 16C chips a bit (which is very plausible), you can expect something closer to 250W TDP. https://www.pcper.com/reviews/Processors/AMD-Ryzen-7-1800X-Review-Now-and-Zen/Power-Consumption-and-Conclusions https://www.pcper.com/reviews/Processors/AMD-Ryzen-7-1800X-R... This is pretty much normal for HEDT chips though. Both Ryzen and Broadwell-E/Haswell-E hit ~230W already when you overclock them - and add another 75-100W for Prime95 loads. I doubt you'll see too many people overclocking the 16C chips even if they're unlocked. You would race right past 300W, probably closer to 400W. You'd need like a 360mm liquid cooler to even think about it.
