AMD Ryzen 7 9700X on the ASUS ROG Strix X870E-E Gaming WiFi
On the ASUS ROG Strix X870E-E Gaming WiFi, the AMD Ryzen 7 9700X runs at 4 % of the board's 2228 W sustained power capacity, which puts the VRM at an estimated 41 °C and leaves clocks untouched.

What happens when you build this
This pairing is not close to any limit. 88 W against 2228 W of capacity leaves the ASUS ROG Strix X870E-E Gaming WiFi running its stages at 4 % load, and our model puts the VRM at 41 °C in a closed case. Nothing about the AMD Ryzen 7 9700X 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 7 9700X's 88 W is measured against.
Buy it on the rest of the specification rather than on power delivery, because at 4 % 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.
The measurement
The gauge shows the estimated VRM temperature under a sustained all-core load, with a thinner copper needle for the brief peak the processor reaches at full boost. The schematic beside it shows the same thing as current per power stage.

What else to know about this pairing
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.
Where the PCIe lanes go
The ASUS ROG Strix X870E-E Gaming WiFi has 4 M.2 slots and one of them is wired to the processor rather than the chipset. Populating the second CPU M.2 slot splits the sixteen CPU graphics lanes, leaving the primary slot at x8. A current graphics card loses one or two percent from that, which matters far less than most forum threads suggest — but it is worth knowing before you wonder why your card reports x8.
The ASUS ROG Strix X870E-E Gaming WiFi takes DDR5, which the AMD Ryzen 7 9700X supports, and validates memory up to DDR5-8000. Firmware is not an issue: the ASUS ROG Strix X870E-E Gaming WiFi ships with a BIOS that already knows Zen 5.

Questions people ask about this pairing
- Will the AMD Ryzen 7 9700X throttle on the ASUS ROG Strix X870E-E Gaming WiFi?
No. The AMD Ryzen 7 9700X draws 88 W in a sustained all-core load and the ASUS ROG Strix X870E-E Gaming WiFi holds about 2228 W, so the VRM sits at an estimated 41 °C and clocks hold.
- How many power phases does the ASUS ROG Strix X870E-E Gaming WiFi have?
18 Vcore power stages rated 110 A each, in a doubled design. Counting only the core rail matters here — vendor marketing often adds the SoC and auxiliary phases to reach a bigger number, and those carry none of the CPU's core load.
- Does the ASUS ROG Strix X870E-E Gaming WiFi need a BIOS update for the AMD Ryzen 7 9700X?
No. The ASUS ROG Strix X870E-E Gaming WiFi ships with a BIOS that already supports Zen 5, so the AMD Ryzen 7 9700X posts out of the box.
- What memory does the AMD Ryzen 7 9700X take on the ASUS ROG Strix X870E-E Gaming WiFi?
DDR5, in up to 4 slots, validated to DDR5-8000 on this board.
- What VRM temperature should I expect with the AMD Ryzen 7 9700X on this board?
Our model estimates 41 °C, from 38 °C of interior case air plus the stress ratio of 0.04 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
- Does an M.2 drive affect the graphics slot on the ASUS ROG Strix X870E-E Gaming WiFi?
Populating the second CPU M.2 slot splits the sixteen CPU graphics lanes, leaving the primary slot at x8.
