The FSP300-50AMB features a standard 24-pin ATX main power connector (P1), a 4-pin ATX auxiliary power connector (P2), and several peripheral power connectors (PA-PF). The 24-pin connector provides +3.3V, +5V, +12V, -12V, and +5Vsb rails, along with ground (COM) and control signals like PS-ON and PWR-OK. Wire colors typically include orange for +3.3V, red for +5V, yellow for +12V, blue for -12V, purple for +5Vsb, and black for ground.
The diagram also indicates airflow direction from front to back, and shows mounting hole specifications (#6-32 UNC x 8). A 'SPEC LABEL' is present on the unit.
