Hi,
I started testing two ASUS slot 1 mb's, a p3b-f rev 1.10 and a p2b 1.04. My PSU is a CX450 from a couple years ago (after ridiculous research on a budget tier PSU- it was well-reviewed). On both of these MB's, I get a warning during boot saying there is a hardware monitor error. These are the p3b-f screen: https://imgur.com/a/iDyMxUP . On every boot I have to hit f1 to proceed past the error, basically, and the fact that it's a -5v problem appears in the BIOS hardware monitor. On the p2b, it just says 0.0V[Err] for the -5v rail in the BIOS hardware monitor. CPU is p2-450.
Any idea why this could be happening? I had no errors/issues with this PSU before, and was running it in a p3 1000 socket 370 gigabyte board the day before I started using it for these ASUS boards. There are no spinning disks- just an ide-microsd and two CD drives).
(these are the power specs for the PSU- error persists with a TNT2 or a voodoo 5500 for agp graphics- it's 15w for 5vsb and 110 for 3.3v and 5v rails:
