Hi, your friend gifted you an old P5B Deluxe from ASUS with the CPU and RAM already installed. I set up my system using a Hydro Pro 500W PSU but didn’t add any extra components. I’m wondering if this board requires a -5V supply. Since my PSU is brand new, it likely doesn’t have that pin, but the manual for P5B Deluxe mentioned something about it. Could that be the reason for the boot issue?

By the time the motherboard came out, the -5 volt standard had largely disappeared from use. An 8-year-old Asus P5A with ISA ports would still boot fine without it, and ISA sound cards should function, though perhaps not optimally.

Okok, it was my last chance, I need to call that mobo or cpu dead, I've tried everything, different sticks of ram on different.ports, cmos reset, and boot without sata disks, maybe I need an idee connected to boot? But it just don't post anything, the vga was working in a different computer so that is not the problem and the psu is brand new, everything lights up, the fans pins but no beep, I guess that "retro pc save project" didn't went well

I questioned whether the CMOS battery had been missing for some time on that board, possibly because the BIOS was damaged. Or maybe it went back to an earlier version that didn’t allow the core quad to run properly.
