Thermaltake Smart BM3 850W Semi-Modular Power Supply Review

Peter Donnell / 8 months ago

Transient Loads

These results measure the power supply from 0% load to 100% load on various rails to simulate a power spike from your system. Typically, we would like to see as small a spike as possible relative to the requested voltage. With modern GPUs being notorious for power spikes, this is becoming more relevant in modern PSU design.

The transients aren’t the fastest I’ve seen, but they’re smooth and clean and level off at their expected targets with no under or overshoot, so again, very good overall.
