Quick Answer

Warranty length usually matters more than connector support: a 10-year warranty signals a PSU built to last, and that protects every component it powers. A 650W 80+ Gold unit with a 10-year warranty (around R1,600 to R2,300 at Evetech) beats a cheaper unit with a 3-year warranty for most SA builds. Treat the warranty as a proxy for internal quality.

Why warranty length is the real signal

PSU warranties scale with internal quality. Budget units ship with 3-year cover; mid-range 80+ Gold units carry 7 to 10 years because the maker trusts the capacitors and the platform. For your build, a 10-year warranty is the single most reliable indicator that the unit will not degrade, sag under load, or take a GPU with it when it fails.

Connector support without overbuying

Check that the unit has the connectors your build actually needs: the right number of PCIe 8-pin (or a native 12V-2x6 for newer GPUs) and enough SATA. Do not pay extra for a 1000W unit just for more cables on a 550W build. A 650W to 750W unit usually has all the connectors a single-GPU SA setup needs for your build.

Picks and setup notes for SA buyers

Prices shift with the Rand-Dollar rate, so treat any band below as a planning figure and check the live Evetech price at checkout. Reliable Evetech-stocked units for your build include the Corsair RM750e, MSI MAG A650BN and Cooler Master MWE Gold 650 V2. Register the warranty at purchase so a claim later is painless.

FAQ

What wattage power supply do I need?

A single-GPU SA gaming PC usually peaks at 400W to 500W, so a 650W to 750W 80+ Gold unit gives safe headroom. Only multi-GPU or extreme overclocked builds need 1000W+, which is wasted money for most buyers.

Does PSU efficiency rating save real money?

The difference between 80+ Bronze and Gold is only a few watts under typical load, saving a handful of Rand a year on a home PC. Efficiency is a useful tie-breaker, but warranty length and build quality matter far more.

Is a modular power supply worth it?

Modular cables make cable management cleaner and improve airflow in glass-panel cases, but they do not change performance. If you are not building for show, a semi-modular Gold unit saves money and powers the system identically.

TIP

Buyer's tip

Before checkout, add up your CPU and GPU TDP, add about 150W for the rest, then pick the nearest 650W to 750W 80+ Gold unit with a 7 to 10 year warranty.
