The Ryzen 9 9900X is stuck at 90W PPT and cannot be adjusted via BIOS settings?
Even under maximum load, the CPU PPT never goes above 90W. The thermal performance is acceptable, but I'm curious if this motherboard has its own strict power limit. I've adjusted the PPT/TDC/EDC settings in the BIOS (ECO mode disabled), but it doesn't seem to make a difference; the changes are saved yet they don't take effect. I can reduce the limits below 90W and it works, but what if the actual consumption is higher than that?
Welcome to the forums, newcomer!
GIGABYTE B650M GAMING WIFI has a 5+2+2 VRM configuration; if you intended to use a Ryzen 9 9900X, you should have considered a better VRM design.
The issue is actually about the motherboard, yes, I'm thinking of other options. It seems this method isn't completely honest from Gigabyte's side; they should be clearer about what their setup can handle.
Also, regarding the 90W specification—does it come pre-set in the motherboard's firmware, or are there other factors involved?
If you're okay with it, what mid-range alternatives are worth considering, and which VRM configurations (12+2+2, 8+2+2) should I keep in mind?
You can locate some information on the board available here, along with a few affordable options that are not too bad:

I concur that manufacturers of motherboards often misrepresent their capabilities. This issue has persisted for some time across both AMD and Intel lines, and it is exacerbated by the lack of full transparency regarding their VRM designs.

I've noticed quite favorable feedback about the ASUS TUF GAMING B650M-E WIFI. However, it features an 8+2+2 configuration, and I'm uncertain about the VRM arrangement needed to fully power the 9900X at maximum output (161 plus some room for overclocking). If that configuration falls short, would a 12+2+2 setup be sufficient? For instance, could the GIGABYTE B650M AORUS PRO AX work in that scenario?
