AMD Ryzen 9 9900X on the ASUS ROG Strix X870E-E Gaming WiFi

On the ASUS ROG Strix X870E-E Gaming WiFi, the AMD Ryzen 9 9900X runs at 7 % of the board's 2228 W sustained power capacity, which puts the VRM at an estimated 43 °C and leaves clocks untouched.

There is a full write-up for this pairing once it reaches the publication queue. Until then, everything the engine knows about it is on this page.

Power delivery

160 W of 2228 W · 18 × 110 A doubled
Each bar is one Vcore power stage, filled to the share of its capacity this processor asks for. The dashed line is the 85 % mark where our model starts predicting clock loss.

This pairing is not close to any limit. 160 W against 2228 W of capacity leaves the ASUS ROG Strix X870E-E Gaming WiFi running its stages at 7 % load, and our model puts the VRM at 43 °C in a closed case. Nothing about the AMD Ryzen 9 9900X pushes this board into the region where clocks start dropping.

The ASUS ROG Strix X870E-E Gaming WiFi carries 18 Vcore power stages rated 110 A each, driven in doubled pairs, which costs a little transient response, with large finned blocks with real thermal mass. That works out to about 2228 W of sustained core power once the design and the cooling are accounted for, which is the number the AMD Ryzen 9 9900X's 160 W is measured against.

Buy it on the rest of the specification rather than on power delivery, because at 7 % of capacity the VRM has stopped being the interesting variable. Count the M.2 slots you need, check the rear ports against what you actually plug in, and let the ASUS ROG Strix X870E-E Gaming WiFi's 18 stages get on with it.

Note: One M.2 slot borrows lanes from the graphics slot

Populating the second CPU M.2 slot splits the sixteen CPU graphics lanes, leaving the primary slot at x8.
