Thermaltake Toughpower GF A3 1050W 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.

Transients are good too, and very clean on the 3v in particular, with a little bit of undershoot on the 5vsb, but overall levelling off after just 30ms, and the 12v reaching a stable target in around 12ms.

As a child still in my 30's (but not for long), I spend my day combining my love of music and movies with a life-long passion for gaming, from arcade classics and retro consoles to the latest high-end PC and console games. So it's no wonder I write about tech and test the latest hardware while I enjoy my hobbies!
