about -5V

[Man-wai Chang ToDie (33.6k)]

What parts of a typical motherboard uses the -5V?

I just replaced an old power supply with an Antec EA380, and the
-5V rose to -6.17V. Is it dangerous though the system became
a bit more stable?

None.

It rose to a lower value???

Only if your system uses the oldest types of 16Kbit DRAM chips or has
an ISA, EISA, or VESA bus slot with a card plugged into it that uses
-5V for chip bias or an analog output. I doubt -5V is connected
anywhere in any contemporary motherboard; the newest ones that may
support it are some MSI or Supermicro oddball Pentium4 models with ISA
slots.

3.3 became defacto as die technology shifted smaller and efficiency
rose.

Ah, no, he's talking about the negative 5 volt supply (which has nothing
to do with the shift from +5V logic to 3.3V logic).
