Intel Core i5-13400 on the MSI MAG B760 Tomahawk WiFi
The Intel Core i5-13400 holds its clocks on the MSI MAG B760 Tomahawk WiFi: the board's 12 Vcore stages carry about 956 W and the processor asks for 65 W in a sustained all-core load, which is 7 % of capacity and an estimated 43 °C at the VRM.

What happens when you build this
There is real headroom here. The MSI MAG B760 Tomahawk WiFi is rated for roughly 956 W of continuous core power and the Intel Core i5-13400 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 — 12 of them at 75 A, teamed in pairs off a shared controller channel — and derating for large finned blocks with real thermal mass, the MSI MAG B760 Tomahawk WiFi holds roughly 956 W indefinitely. The Intel Core i5-13400 asks for 65 W of that, and at boost it can reach 148 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 MSI MAG B760 Tomahawk WiFi's 12 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: PCIe 5.0 from the CPU runs at 4.0 speeds here
The Intel Core i5-13400 provides PCIe 5.0 lanes but the MSI MAG B760 Tomahawk WiFi wires its slots for PCIe 4.0. Nothing stops working; a Gen 5 SSD simply runs at Gen 4 speed, which no game notices.
Where the PCIe lanes go
The MSI MAG B760 Tomahawk WiFi 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 MSI MAG B760 Tomahawk WiFi takes DDR5, which the Intel Core i5-13400 supports, and validates memory up to DDR5-7200. Firmware is not an issue: the MSI MAG B760 Tomahawk WiFi ships with a BIOS that already knows Raptor Lake.
Boards that run the Intel Core i5-13400 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 i5-13400 throttle on the MSI MAG B760 Tomahawk WiFi?
No. The Intel Core i5-13400 draws 65 W in a sustained all-core load and the MSI MAG B760 Tomahawk WiFi holds about 956 W, so the VRM sits at an estimated 43 °C and clocks hold.
- How many power phases does the MSI MAG B760 Tomahawk WiFi have?
12 Vcore power stages rated 75 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 MSI MAG B760 Tomahawk WiFi need a BIOS update for the Intel Core i5-13400?
No. The MSI MAG B760 Tomahawk WiFi ships with a BIOS that already supports Raptor Lake, so the Intel Core i5-13400 posts out of the box.
- What memory does the Intel Core i5-13400 take on the MSI MAG B760 Tomahawk WiFi?
DDR5, in up to 4 slots, validated to DDR5-7200 on this board.
- What VRM temperature should I expect with the Intel Core i5-13400 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.
