ASUS ROG Maximus Z790 Apex PCB Breakdown notes
Added 2023-09-24 04:51:37 +0000 UTCA board so overkill that it uses 5x 56uF SP caps for filtering the PCI-e slot's 12V instead of the typical 1x270uF through hole polymer.
features:
POST code
Safeboot button
PWR button
RST/flex button
retry button
BCLK +/- buttons
dual BIOS
CLR_CMOS
BIOS flashback

400A ~30W

Hi OnSemi 4C10C // probably just a new version of the 4C10N
Lo OnSemi 4C10C
thank you to ASUS for providing the board.

Any chance you'll be taking a look at the Apex Encore?

Maybe they have the main config and Vishay as their second vendor? I've only seen Vishay SPS' on that one board though and when I bought it myself it was populated with Renesas ISL99390's.

2023-09-25 15:30:19 +0000 UTCI think it's just a consistency thing. I think basically all the high end ASUS Z790 boards use the exact same VCCIN and VDD2 configuration so it would add extra support work to run them of the RAA229131.
Actually Hardcore Overclocking (Buildzoid)
2023-09-25 10:49:40 +0000 UTCStrange to use RAA229131 which is a dual rail 20 phase controller and only attach 12 phases albeit with teaming. Any Idea why the spare phases werent reused for VCCIN or VDD2? Simplicity of design maybe? I'd bet they started with a 20phase design eg from the Maximus hero but wanted to up the number of phases for marketing with minimal extra work.
