Quick installation Instructions

The PICOPSU-90 has been specifically designed for the Mini-ITX form
factor, thus eliminating the need for ATX power cables. It is also 1U
compliant – height will not exceed 1U form factor.

1) After the picoPSU module was ‘snapped in’, hook the hard drive
power or floppy power to your floppy/hard drives. If more hard drives or
floppy connectors are needed, use a HDD/floppy “Y” splitter cable.
