The Ugandan Power Environment
In Kampala and surrounding areas, power stability can be inconsistent. Cheap power supplies operate at their limit and have no "protection" against sudden voltage spikes. By choosing a PSU with headroom (e.g., an 850W unit for a 500W system), you ensure the components inside the PSU are not stressed, extending the life of your entire PC.
Transient Spikes
Modern GPUs like the RTX 30 and 40 series have "transient spikes"—millisecond bursts where they draw double their rated power. A calculator that only shows the base TDP will often underestimate your needs, leading to random shut-downs during heavy gaming sessions.
