Reliable Power for Your Desktop Build or Upgrade
The Astrum PS400S is a 300W ATX PS2 power supply built for South African mains voltage – designed for office desktop PCs, budget home builds, and replacement PSU upgrades. A complete connector set, 120mm silent fan, and 6-protection safety system make it a dependable choice for everyday computing.
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.
