PSU
Trimond motherboards are designed to be connected to a soft-switch PSU, with 5V standby. If the 5V standby
current is insufficient, the PSU may deregulate and possibly damage the motherboard. Ensure that at least 30mA
is available to the 5V standby output.
If you wish to use a hard-switch PSU, it is necessary to change a flag in the manufacturer settings of the BIOS
and provide current to the motherboard 5V standby connector. Please contact the Motherboard Division for full
instructions.
The power connector located on the NLX riser.
COOLING
PL3 is a three-pin system tacho-fan connector. Variable speed is
supported by ACPI-aware operating systems e.g. Windows 98.
PL3
JP9 on the riser (if supplied) provides an
additional fan connector.
