Intel Core i9-13900KS on the ASUS ROG Strix Z790-E Gaming WiFi II

Pairing the Intel Core i9-13900KS with the ASUS ROG Strix Z790-E Gaming WiFi II puts 253 W through a 2104 W power stage array — 12 % of what the board holds — for an estimated VRM temperature of 46 °C and no measurable clock loss.

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

253 W of 2104 W · 18 × 110 A teamed
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. 253 W against 2104 W of capacity leaves the ASUS ROG Strix Z790-E Gaming WiFi II running its stages at 12 % load, and our model puts the VRM at 46 °C in a closed case. Nothing about the Intel Core i9-13900KS pushes this board into the region where clocks start dropping.

The ASUS ROG Strix Z790-E Gaming WiFi II carries 18 Vcore power stages rated 110 A each, teamed in pairs off a shared controller channel, with large finned blocks with real thermal mass. That works out to about 2104 W of sustained core power once the design and the cooling are accounted for, which is the number the Intel Core i9-13900KS's 253 W is measured against.

Buy it on the rest of the specification rather than on power delivery, because at 12 % 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 Z790-E Gaming WiFi II's 18 stages get on with it.

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

Installing a drive in the CPU-fed Gen 5 M.2 slot drops the primary graphics slot from x16 to x8.
