Intel Core i7-13700K on the ASUS Prime Z790M-Plus
Pairing the Intel Core i7-13700K with the ASUS Prime Z790M-Plus puts 245 W through a 372 W power stage array — 66 % of what the board holds — for an estimated VRM temperature of 81 °C and roughly 1 % off sustained clocks.

What happens when you build this
Expect a small, measurable loss. Running 245 W through 372 W of capacity leaves the ASUS Prime Z790M-Plus at 66 % load, which our model turns into 81 °C at the VRM and about 1 % off sustained clocks for the Intel Core i7-13700K. It is a usable build, but the board is the part holding it back.
The ASUS Prime Z790M-Plus carries 10 Vcore power stages rated 50 A each, teamed in pairs off a shared controller channel, with a thin heatsink that helps at idle more than under load. That works out to about 372 W of sustained core power once the design and the cooling are accounted for, which is the number the Intel Core i7-13700K's 245 W is measured against.
You can build this. If the machine mostly games, the 1 % our model expects will not show up in a frame-rate graph, because games rarely hold all cores at full power long enough to matter. If it renders, compiles or encodes for more than a few minutes at a time, the next board up recovers that 1 % for less than the price of the Intel Core i7-13700K's next model up.
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 Prime Z790M-Plus keeps its 3 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 Prime Z790M-Plus takes DDR5, which the Intel Core i7-13700K supports, and validates memory up to DDR5-7200. Firmware is not an issue: the ASUS Prime Z790M-Plus ships with a BIOS that already knows Raptor Lake.

Questions people ask about this pairing
- Will the Intel Core i7-13700K throttle on the ASUS Prime Z790M-Plus?
Yes, by about 1 % of sustained all-core clock speed. The Intel Core i7-13700K asks for 245 W and the ASUS Prime Z790M-Plus carries roughly 372 W, which puts its power stages at an estimated 81 °C.
- How many power phases does the ASUS Prime Z790M-Plus have?
10 Vcore power stages rated 50 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 Prime Z790M-Plus need a BIOS update for the Intel Core i7-13700K?
No. The ASUS Prime Z790M-Plus ships with a BIOS that already supports Raptor Lake, so the Intel Core i7-13700K posts out of the box.
- What memory does the Intel Core i7-13700K take on the ASUS Prime Z790M-Plus?
DDR5, in up to 4 slots, validated to DDR5-7200 on this board.
- What VRM temperature should I expect with the Intel Core i7-13700K on this board?
Our model estimates 81 °C, from 38 °C of interior case air plus the stress ratio of 0.66 scaled by 65 °C. Measured numbers move with case airflow and ambient temperature, so treat this as a band rather than a reading.
