Intel Core i5-12400 on the ASUS TUF Gaming Z790-Plus WiFi D4
On the ASUS TUF Gaming Z790-Plus WiFi D4, the Intel Core i5-12400 runs at 7 % of the board's 918 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 TUF Gaming Z790-Plus WiFi D4 is rated for roughly 918 W of continuous core power and the Intel Core i5-12400 draws 65 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 — 16 of them at 60 A, teamed in pairs off a shared controller channel — and derating for a solid block across both banks, the ASUS TUF Gaming Z790-Plus WiFi D4 holds roughly 918 W indefinitely. The Intel Core i5-12400 asks for 65 W of that, and at boost it can reach 117 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 TUF Gaming Z790-Plus 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.

Power delivery
Where the PCIe lanes go
The ASUS TUF Gaming Z790-Plus WiFi D4 keeps its 4 M.2 slots clear of the graphics lanes, so the primary slot stays at x16 whatever you install. That is one fewer configuration trap than boards that route a second M.2 slot from the processor.
The ASUS TUF Gaming Z790-Plus WiFi D4 takes DDR4, which the Intel Core i5-12400 supports, and validates memory up to DDR4-5333. Firmware is not an issue: the ASUS TUF Gaming Z790-Plus WiFi D4 ships with a BIOS that already knows Alder Lake.
Boards that run the Intel Core i5-12400 without throttling
Each of these keeps the processor under a third of the board's sustained power capacity, and each has a listing we can verify.

Questions people ask about this pairing
- Will the Intel Core i5-12400 throttle on the ASUS TUF Gaming Z790-Plus WiFi D4?
No. The Intel Core i5-12400 draws 65 W in a sustained all-core load and the ASUS TUF Gaming Z790-Plus WiFi D4 holds about 918 W, so the VRM sits at an estimated 43 °C and clocks hold.
- How many power phases does the ASUS TUF Gaming Z790-Plus WiFi D4 have?
16 Vcore power stages rated 60 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 TUF Gaming Z790-Plus WiFi D4 need a BIOS update for the Intel Core i5-12400?
No. The ASUS TUF Gaming Z790-Plus WiFi D4 ships with a BIOS that already supports Alder Lake, so the Intel Core i5-12400 posts out of the box.
- What memory does the Intel Core i5-12400 take on the ASUS TUF Gaming Z790-Plus 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 i5-12400 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.
