First, connect the main power connector (1) on the power supply unit to the mother board.
Some motherboards require a 20-pin connector, others a 24-pin connector. For this reason the
Pecos 520W has a 20-pin connector with an additional 4-pin connector. This 4-pin 20 to 24-pin
combo connector extender must not be plugged into the 12V AUX/P4 socket. It should either be
plugged into the 24-pin extended ATX socket or, if an ATX 20-pin socket is present, must be left
unplugged.
There is a dedicated 4-pin +12V plug (2) for the 12V AUX connector which is easy to identify as it
only has two black and two yellow cables.
The 5-pin SATA power connector (3) is a very flat, black connector which is used to connect the
power supply unit to a SATA hard drive or SATA CD-ROM/DVD drives or writers.
The 6-pin PCI Express power connector (4) is intended for PCI Express graphics cards. Certain
AGP graphics cards as well as IDE hard drives and CD-ROM and DVD drives and writers require
