Complete Connector Set

Everything your build needs in one PSU: 24-pin ATX for the motherboard, 8-pin / 4+4-pin EPS12V for the CPU, 6-pin PCI-E for a discrete GPU, 3 x SATA for storage drives, and 2 x 4-pin Molex for peripherals. Flat cable design helps keep your build tidy and airflow unobstructed.

6-Protection Safety System

OVP, OPP, OCP, OTP, SCP, and UVP protection work together to help shield your components from power faults, including overvoltage, overpower, overcurrent, overtemperature, short-circuit, and undervoltage issues. In South Africa’s variable power environment, a protected PSU is not optional – it is essential.

120mm Silent Fan

The large 120mm fan moves air efficiently at lower RPM than smaller fans, helping keep the PS400S running quietly during normal desktop workloads. Effective thermal management supports extended daily use.

Built for South Africa

220V AC input is designed for South African mains supply. The ATX PS2 form factor fits standard ATX tower, mid-tower, and compatible microATX cases. A built-in power switch allows clean on/off control without unplugging the power cable.
