Description
The GIGABYTE P550B is an ATX power supply unit with a total power output of 550 W and a black colour, with dimensions of 150 x 86 x 140 mm (width x height x depth). Its 20+4 pin connector allows conventional ATX configurations to be powered, and it supports an input voltage of 100 - 240 V with a current of 8 - 4 A and an input frequency of 50 - 60 Hz. It features active power factor correction and achieves an efficiency of 85%. It distributes the load across its rails: up to 43.5 A on the +12V line, 18 A on the +3.3V line and 15 A on the +5V line, while the auxiliary rails support 3 A on +5Vsb and 0.3 A on -12V. The combined power outputs are distributed as 522 W for +12 V, 108 W for +5 V, 108 W for 3.3 V, 15 W for +5 VSB and 3.6 W for -12V. It includes protection features against overcurrent, overvoltage, overpower, overheating, short circuit and undervoltage, with a hold-up time of 16 ms.
