Intel Core i9-13900K on the ASUS ROG Strix Z790-A Gaming WiFi D4
The Intel Core i9-13900K holds its clocks on the ASUS ROG Strix Z790-A Gaming WiFi D4: the board's 16 Vcore stages carry about 1190 W and the processor asks for 250 W in a sustained all-core load, which is 21 % of capacity and an estimated 52 °C at the VRM.

What happens when you build this
There is real headroom here. The ASUS ROG Strix Z790-A Gaming WiFi D4 is rated for roughly 1190 W of continuous core power and the Intel Core i9-13900K draws 250 W once a ten-minute render settles, so the power stages spend their time well inside their comfortable range. An estimated 52 °C is the kind of VRM temperature that never appears in a log, and the board will not be the reason a benchmark run finishes slower than it started.
Counting only the stages that feed the core rail — 16 of them at 70 A, teamed in pairs off a shared controller channel — and derating for large finned blocks with real thermal mass, the ASUS ROG Strix Z790-A Gaming WiFi D4 holds roughly 1190 W indefinitely. The Intel Core i9-13900K asks for 250 W of that, and at boost it can reach 253 W.
Buy it on the rest of the specification rather than on power delivery, because at 21 % 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-A Gaming WiFi D4's 16 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
The CPU-attached M.2 slot shares lanes with the graphics slot, which drops to x8 when it is populated.
Where the PCIe lanes go
The ASUS ROG Strix Z790-A Gaming WiFi D4 has 4 M.2 slots and one of them is wired to the processor rather than the chipset. The CPU-attached M.2 slot shares lanes with the graphics slot, which drops to x8 when it is populated. 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 Z790-A Gaming WiFi D4 takes DDR4, which the Intel Core i9-13900K supports, and validates memory up to DDR4-5333. Firmware is not an issue: the ASUS ROG Strix Z790-A Gaming WiFi D4 ships with a BIOS that already knows Raptor Lake.

Questions people ask about this pairing
- Will the Intel Core i9-13900K throttle on the ASUS ROG Strix Z790-A Gaming WiFi D4?
No. The Intel Core i9-13900K draws 250 W in a sustained all-core load and the ASUS ROG Strix Z790-A Gaming WiFi D4 holds about 1190 W, so the VRM sits at an estimated 52 °C and clocks hold.
- How many power phases does the ASUS ROG Strix Z790-A Gaming WiFi D4 have?
16 Vcore power stages rated 70 A each, in a teamed 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 Z790-A Gaming WiFi D4 need a BIOS update for the Intel Core i9-13900K?
No. The ASUS ROG Strix Z790-A Gaming WiFi D4 ships with a BIOS that already supports Raptor Lake, so the Intel Core i9-13900K posts out of the box.
- What memory does the Intel Core i9-13900K take on the ASUS ROG Strix Z790-A Gaming WiFi D4?
DDR4, in up to 4 slots, validated to DDR4-5333 on this board.
- What VRM temperature should I expect with the Intel Core i9-13900K on this board?
Our model estimates 52 °C, from 38 °C of interior case air plus the stress ratio of 0.21 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 Z790-A Gaming WiFi D4?
The CPU-attached M.2 slot shares lanes with the graphics slot, which drops to x8 when it is populated.
