Quick Answer
For Minecraft with shaders, choose power supply by matching the part to the job first, then compare price, warranty and the exact spec you will use. A sensible SA shortlist starts around R900 to R2,800, with Corsair RM750e 750W as a named reference and 650W to 850W 80 Plus Gold as the performance target. SA buyers should treat PSU quality as protection for the whole PC, not a visible accessory.
Match The Power Supply To The Work
Start with the result the buyer needs from Minecraft with shaders, not the flashiest line on the box. The useful comparison is whether the power supply removes a clear delay, comfort issue, compatibility limit or performance ceiling. If it does not change the day-to-day result, keep the spend lower and protect budget for the parts that do.
Specs And Numbers To Check
Use 650W to 850W 80 Plus Gold as the working target, then check the supporting details around it. A monitor needs the right cable and GPU output, storage needs a compatible M.2 slot, a PSU needs enough clean wattage, and a case needs physical clearance. The spec only matters when the rest of the setup can use it.
SA Buyer Checks
South African buyers should plan around desk space, room temperature, courier handling, warranty process and the parts already owned. A student in a res room, a parent buying for a teen and a home-office user in Johannesburg or Cape Town can all need different priorities from the same product category. The best choice is the one that fits the room and the workload without forcing a second purchase.
