Quick Answer

Buy now if the power supply reaches a reputable 650W unit with the right PCIe cables and fixes the school coding club limit today; upgrade later only when the cheaper option leaves a supported next step. Plan around R1,200 to R3,500 and compare Corsair RM750e, Cooler Master MWE Gold 750, and Antec NeoECO 650W-class PSUs. Check current Evetech stock before checkout, because exact live pricing can move.

Buy Now Versus Upgrade Later

Start with the limit you are trying to remove: slow work, noise, cramped desk space, weak coverage, poor comfort, or a part blocking the next upgrade. For school coding club, the right power supply removes that limit without creating a new one.

Named comparison points keep the choice grounded: Corsair RM750e, Cooler Master MWE Gold 750, and Antec NeoECO 650W-class PSUs. Use them as a class reference, not a promise of live price. The planning band is R1,200 to R3,500.

Specs That Actually Matter

Protect the floor first: a reputable 650W unit with the right PCIe cables. After that, check connector type, clearance, noise, firmware support, mounting hardware, cable length, and software control. The part should still make sense with a Ryzen 5, Core i5, RTX 4060, or similar mid-range system.

Do not pay for a feature the setup cannot use. A high refresh screen needs enough GPU frames; fast DDR5 needs a board and CPU that can train it; a bigger PSU still needs the correct PCIe cable. For family rooms and school PCs, quiet operation and cable quality make support easier than peak wattage.

Local Fit Before Checkout

For SA buyers, the hidden costs are often physical: adapters, extra fans, monitor arms, longer Ethernet cables, USB hubs, thermal paste, or mounting brackets. If the shortlist needs two add-ons to work properly, move up one tier instead of forcing the bargain.

FAQ

What minimum spec should I accept for school coding club?

Accept a reputable 650W unit with the right PCIe cables as the floor for a sensible power supply. Below that, the saving is usually smaller than the cost of replacing the part sooner.

How much should I budget in South Africa?

TIP

Buying Tip

Check GPU cable needs and PSU length; wattage alone does not prove compatibility.
