AMD Ryzen 5 9600 on the MSI PRO A620M-E
The AMD Ryzen 5 9600 holds its clocks on the MSI PRO A620M-E: the board's 6 Vcore stages carry about 289 W and the processor asks for 88 W in a sustained all-core load, which is 30 % of capacity and an estimated 58 °C at the VRM.

Power delivery
This pairing is not close to any limit. 88 W against 289 W of capacity leaves the MSI PRO A620M-E running its stages at 30 % load, and our model puts the VRM at 58 °C in a closed case. Nothing about the AMD Ryzen 5 9600 pushes this board into the region where clocks start dropping.
The MSI PRO A620M-E carries 6 Vcore power stages rated 55 A each, each driven by its own controller channel, with a thin heatsink that helps at idle more than under load. That works out to about 289 W of sustained core power once the design and the cooling are accounted for, which is the number the AMD Ryzen 5 9600's 88 W is measured against.
Buy it on the rest of the specification rather than on power delivery, because at 30 % 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 PRO A620M-E's 6 stages get on with it.
Warning: This board needs a BIOS update first
The MSI PRO A620M-E shipped with firmware that predates Zen 5, so a board taken off the shelf may not post with the AMD Ryzen 5 9600 until its BIOS is updated.
Blocker: No USB BIOS Flashback on this board
The MSI PRO A620M-E cannot flash firmware without a working CPU installed, so if the board is on old firmware you need to borrow an older AM5 processor or have a shop flash it before the AMD Ryzen 5 9600 will boot.
Note: PCIe 5.0 from the CPU runs at 4.0 speeds here
The AMD Ryzen 5 9600 provides PCIe 5.0 lanes but the MSI PRO A620M-E wires its slots for PCIe 4.0. Nothing stops working; a Gen 5 SSD simply runs at Gen 4 speed, which no game notices.
