Overclocking

Recommended wattage is an estimation of system power demand. Actual power demands may vary based on specific components, usage, and many other factors.
Testing was conducted by ASUS using pre-production PSUs.
Overclocked power consumption is an estimated figure derived from the maximum CPU TDP and GPU TGP.
Stock power consumption data is derived from default GPU TGP and CPU TDP (the default CPU TDP is listed below): Intel Core i3 and Core i5: Intel Core i5-7640X, TDP = 112W; Intel Core i7: Intel Core i7-9800X, TDP = 105W ~ 165W; Intel Core i9: Intel Core i9-10980XE, TDP = 165W; Intel HEDT Series: Intel® Xeon® Platinum 8380HL, TDP = 280W; AMD Ryzen 3 and Ryzen 5: AMD Ryzen™ 5 3600X, TDP = 112W; AMD Ryzen 7: AMD Ryzen™ 7 3800XT, TDP = 105W ~ 165W; AMD Ryzen 9: AMD Ryzen™ 9 3900XT, TDP = 165W; AMD Ryzen Threadripper: AMD Ryzen™ Threadripper™ 3990X, TDP = 280W.
