The power supply is the one component that can take the rest of the build with it when it fails, and it is the one people shop for last with whatever budget survived the GPU. The power supply price range in South Africa opens at R599 and runs to R13,199, with the useful decisions clustered between R900 and R2,500. Here is what the current lineup costs in Rand including VAT, and how to read a wattage figure honestly.

Quick Answer

A PC power supply is available at Evetech from R599 including VAT, with 59 units in stock. The entry rung is 450W to 550W with an 80 PLUS Bronze rating, which suits an office machine or a build with no dedicated graphics card. Most gaming builds want 650W to 850W, and a single modern high-end GPU is comfortable on a quality 850W unit. Efficiency rating and cable modularity, not raw wattage, are what separate units at the same output.

  • GAMDIAS HELIOS M1-450B 450W 80+ Bronze Power Supply: R599
  • EINAREX APEX L1 750W Bronze PSU with Semi-Modular Design: R749
  • Gamemax MAX P550B 550W ATX 3.1 Bronze PSU (Black): R799
  • Gamdias HELIOS M2-550B 550W ATX 3.1 Bronze PSU: R899
  • EINAREX APEX L1 550W Bronze Semi-Modular PSU: R899
  • Gamdias KRATOS E1-600 RGB 600W Power Supply with Addressable RGB: R949

Read that list carefully, because it does not sort the way you expect. The 750W EINAREX at R749 costs less than several 550W units above it, which is a reminder that wattage alone does not set the price in this segment. Semi-modular cabling, the ATX 3.1 standard and the quality of the internal components all pull on the number independently.

ATX 3.1 is worth knowing about. It is the current specification, and it covers the transient power spikes that modern graphics cards produce, along with the 12V-2x6 connector used by recent high-end GPUs. A Bronze-rated ATX 3.1 unit is a better buy than an older Bronze unit at the same wattage and price. The full power supply range lists the standard on each product.

⚡ How much wattage do you actually need

Add up the two components that matter and ignore the rest. A modern graphics card and CPU together account for the overwhelming majority of a gaming PC's draw; drives, fans and RGB are rounding errors. Take the GPU manufacturer's recommended system wattage, which already includes headroom, and treat that as your floor rather than your target.

In practice that puts an entry gaming build with a mid-range card on 550W to 650W, a mainstream 1440p build on 750W, and a build with a current high-end card on 850W or above. Buying well beyond that does not make the machine faster or safer, though it does leave room for a future GPU upgrade, which is a legitimate reason to size up one step. Units above 700W cover most of that middle ground.

The one place to be genuinely cautious is the very bottom of the market. A 450W unit is fine behind an office machine or a build using integrated graphics. It is not the place to save R300 on a system with a dedicated card, because a supply running near its ceiling runs hot, ages faster and gets loud.

🔌 Efficiency, modularity and the cables you will curse

The 80 PLUS rating measures how much of the power drawn from the wall reaches your components. Bronze is the practical baseline and covers everything in the entry list. Gold costs more, wastes less as heat and usually comes with better internals and a longer warranty, which is the real argument for it. The electricity saving alone takes years to repay the difference, so buy Gold for the build quality and the quieter fan, not for the running cost.

Modularity is about the cables. A non-modular unit has every cable permanently attached, so unused ones live in a bundle behind the motherboard tray. Semi-modular units, which several entry models above already are, fix the essential cables and let you leave the rest in the box. That is a real quality-of-life difference in a small case, and it improves airflow.

Check two physical things before ordering: that the unit is standard ATX depth for your case, and that it carries the connectors your graphics card needs. The best-selling power supplies are popular largely because they get those two details right for common builds.

Frequently Asked Questions

How much does a PC power supply cost in South Africa?

Power supplies are available at Evetech from R599 including VAT, with 59 units in stock. The range runs to R13,199 for high-wattage platinum-class units.

What wattage power supply do I need for gaming?

Most gaming builds are comfortable on 650W to 850W. Use your graphics card manufacturer's recommended system wattage as the floor, since it already includes headroom, and size up one step if you plan a future GPU upgrade.

Is 80 PLUS Gold worth the extra money over Bronze?

Buy Gold for the better internal components, quieter fan and longer warranty rather than for the electricity saving, which takes years to repay the difference. Bronze is a perfectly sound baseline for a mainstream build.

What is ATX 3.1 and do I need it?

ATX 3.1 is the current power supply standard. It handles the brief power spikes modern graphics cards produce and includes the 12V-2x6 connector used by recent high-end GPUs. At the same price and wattage, choose it over an older unit.

What does semi-modular mean?

The essential cables are permanently attached and the rest detach, so you only install what your build uses. It makes cable management easier and improves airflow, particularly in a small case.
