Looks kind of similar to the rather common IP-S400CQ2-0 at first glance, but there are a few differences

The topology is STF, with an ST W12NK90Z FET (11A, 0.72Ω RDS-on)

5V and 3.3V rails use SIRectifier 4045PTs (40A). 12V uses a single MBR20100CT

The fan is an ARX sleeve bearing, and it's stuck. It looks like the thick grease they used got pushed out of the bearing.

And here's the end result. The caps are all bad and the thing won't start.
I'm hoping that it will be fine if I just recap it and give the fan some better lubricant.
