Evaluation II
12V ripple, too, is judged from 100W to 1,200W in this instance. The average ripple, from five data points, is, once again, mighty impressive, and the super-low numbers are helped by the Type-4 cables we spoke about on the first page.
Stepping up the power in 100W increments reveals the AX1600i's 140mm fan kicks into action at around 700W load, with an ambient temperature of 23°C, thus acting like a passively-cooled model up until that figure. In reality, this means that almost any gaming rig won't pull enough juice to turn the fan on - a dual GeForce GTX Titan X and Core i7-6950X OC can just about manage that figure under maximum load.
We'd imagine only the mining crowd can get the fan to turn on, and when it does, the noise profile is predictable. We only managed 1,200W load, as you know, and the supply was deemed to be quiet, verging on near-inaudible, at that time.
Rounding out an excellent set of results, the AX1600i doesn't become warm, either.
