Thermaltake Toughpower GF3 Snow 1200 Watt ATX 3.0 Power Supply Review

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 specifications for ATX 3.0 were released in February 2022. It includes the new 16-Pin 12vHPWR connector that can deliver up to 600 W to graphics cards. These incorporate data lines for components to negotiate power capabilities with the PSU so they do not draw more power than the PSU is capable of delivering. The specification also has more strict requirements for handling spikes, two times the nominal output for 100 microseconds.
Overall, a very good result, but there was a slight flutter in the 12v rail when switched on, but is far from anything to be concerned about as the time to hit 12v was still very quick and stable enough once reached.
