X870 Nova WiFi BIOS Query and USB C issue

Hello in the latest BIOS update (4.10 2026/2/25) for my board (PHANTOM GAMING X870 Nova WiFi) I am wondering what does this do?

1. Update AGESA to ComboAM5 PI 1.3.0.0a.

Specifically what is AGESA and ComboAM5? What does this update fix?


I also have another question. I don't know why but the Front Panel Type C USB 3.2 Gen2x2 Header (USB32_TC1) which is for my USB C slot on top of my case? isn't working properly. I have it connected in the correct way but it won't load my drive. In Device Manager it shows Unknown USB Device (Device Descriptor Request Failed). In the details under the General tab it shows Windows has stopped this device because it has reported problems. (Code 43).

I have my old Samsung 970 EVO NVMe M.2 SSD 1TB inside an enclosure. At first I thought it maybe faulty. But then I tried another [https://us.transcend-info.com/product/portable-ssd/esd310]USB C drive[/URL] and it reports the same issue. So I'm thinking either its not getting supplied enough power or maybe I need a BIOS update?

AGESA is the AMD in house term for AMD's BIOS backbone/core firmware
(AMD Generic Encapsulated Software Architecture). This is the base BIOS firmware
AMD ships out to all it's motherboard partners then from there it is customized
to suit each motherboard model it is applied to. Basically, it is the core of the
BIOS (or UEFI as it is called these days).

ComboAM5 PI 1.3.0.0a is just the version number of the base AGESA. AM5 is the
platform the AGESA is designed for. This version is mentioned in the BIOS description
so that people know that that particular BIOS update includes a core update (AGESA)
and isn't simply a refinement/tweaked version of the last AGESA version which
also happens quite often to fix bugs, add RAM support etc.

Basically not every BIOS update includes an AGESA update. New AGESA versions typically
indicate more major core changes like adding new CPU support, major security
updates and other more in depth changes. BIOS updates that don't include a new
AGESA version are more common and can be thought of as optimizations and bug
fixes rather than a full fledged BIOS update.

As for the USB C issue, that can be tricky to troubleshoot. Have you tried any
other USB C devices in the front panel port? You said that you are sure the front
panel port is connected correctly to the header so I will just assume that you
have already double checked it. You can also try using your enclosure with a
shorter USB C cable (15cm or less), I have seen quite a few issues with devices
powered by USB C and cables that are too long and not properly rated for the
power needed. You have to bare in mind that you need to include the length of
the cable that connects from the port itself to the motherboard too. So while
a device may work just fine connected to one of the rear IO USB C ports it may
not work when connected to the one on the case front because it added 30cm+ of
cable into the mix and the voltage dropped too much.

Hope this helps.
