A good power supply is the unsung hero of a stable PC – it protects every component and keeps your system running cleanly. This guide covers the best PSUs in stock at ADGear, with local Rand pricing and warranty. From budget non-modular units to fully modular Gold-rated powerhouses, here’s how to choose the right one.
How to Choose a Power Supply
- Wattage: Match the PSU to your components. Entry builds run happily on 450–550W; mid-range gaming rigs want 650–750W; high-end GPUs and CPUs need 850W and up.
- 80 PLUS rating: This certifies efficiency. Bronze is solid value, Gold runs cooler and wastes less power – ideal for higher-end systems.
- Modularity: Non-modular has fixed cables (cheapest); semi-modular lets you detach some; fully modular lets you use only the cables you need for the tidiest, best-airflow builds.
- ATX 3.1 & PCIe 5.x: Newer standards with the 12V-2×6 connector are built for modern graphics cards and handle power spikes better.
- Brand and warranty: A quality unit from a trusted brand protects your whole investment – don’t skimp here.

Frequently Asked Questions
How much wattage do I need for my PC?
Entry builds run on 450–550W, mid-range gaming rigs want 650–750W, and high-end systems with powerful GPUs need 850W or more. Always leave some headroom above your estimated draw.
What does 80 PLUS Gold mean?
It’s an efficiency rating. Gold units waste less power as heat than Bronze ones, run cooler and quieter, and are well suited to higher-end systems.
Is a modular power supply worth it?
Fully modular units let you connect only the cables you need, which means tidier builds and better airflow. Semi-modular is a great middle ground, while non-modular is the most affordable.
What is ATX 3.1 and do I need it?
ATX 3.1 is the latest standard with the 12V-2×6 connector designed for modern graphics cards. It handles power spikes better, so it’s a smart choice for new GPU builds.
