Intel Core i5-12600K on the ASUS ROG Strix Z790-E Gaming WiFi II
On the ASUS ROG Strix Z790-E Gaming WiFi II, the Intel Core i5-12600K runs at 7 % of the board's 2104 W sustained power capacity, which puts the VRM at an estimated 43 °C and leaves clocks untouched.

What happens when you build this
There is real headroom here. The ASUS ROG Strix Z790-E Gaming WiFi II is rated for roughly 2104 W of continuous core power and the Intel Core i5-12600K draws 145 W once a ten-minute render settles, so the power stages spend their time well inside their comfortable range. An estimated 43 °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 — 18 of them at 110 A, teamed in pairs off a shared controller channel — and derating for large finned blocks with real thermal mass, the ASUS ROG Strix Z790-E Gaming WiFi II holds roughly 2104 W indefinitely. The Intel Core i5-12600K asks for 145 W of that, and at boost it can reach 150 W.
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 Z790-E Gaming WiFi II'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
Installing a drive in the CPU-fed Gen 5 M.2 slot drops the primary graphics slot from x16 to x8.
Where the PCIe lanes go
The ASUS ROG Strix Z790-E Gaming WiFi II has 5 M.2 slots and one of them is wired to the processor rather than the chipset. Installing a drive in the CPU-fed Gen 5 M.2 slot drops the primary graphics slot from x16 to 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 Z790-E Gaming WiFi II takes DDR5, which the Intel Core i5-12600K supports, and validates memory up to DDR5-8000. Firmware is not an issue: the ASUS ROG Strix Z790-E Gaming WiFi II ships with a BIOS that already knows Alder Lake.

Questions people ask about this pairing
- Will the Intel Core i5-12600K throttle on the ASUS ROG Strix Z790-E Gaming WiFi II?
No. The Intel Core i5-12600K draws 145 W in a sustained all-core load and the ASUS ROG Strix Z790-E Gaming WiFi II holds about 2104 W, so the VRM sits at an estimated 43 °C and clocks hold.
- How many power phases does the ASUS ROG Strix Z790-E Gaming WiFi II have?
18 Vcore power stages rated 110 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-E Gaming WiFi II need a BIOS update for the Intel Core i5-12600K?
No. The ASUS ROG Strix Z790-E Gaming WiFi II ships with a BIOS that already supports Alder Lake, so the Intel Core i5-12600K posts out of the box.
- What memory does the Intel Core i5-12600K take on the ASUS ROG Strix Z790-E Gaming WiFi II?
DDR5, in up to 4 slots, validated to DDR5-8000 on this board.
- What VRM temperature should I expect with the Intel Core i5-12600K on this board?
Our model estimates 43 °C, from 38 °C of interior case air plus the stress ratio of 0.07 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-E Gaming WiFi II?
Installing a drive in the CPU-fed Gen 5 M.2 slot drops the primary graphics slot from x16 to x8.
