On the performance front, the Ultra X3 1.6kW unit does great. All of the rails are strong and solid, staying well within the specifications. The voltage regulation circuit does it’s job extremely well, keeping the voltage lines stable and especially the 12V line which has an extremely wide range up to 117A output. Despite its monstrous output this unit does not fail, therefore staying stable all of the time.
Efficiency wise, the X3 1.6kW unit leaves something to be desired. It even comes slightly short of the manufacturer’s specifications for 80% efficiency at typical load. The average efficiency of the unit is about 77%, which is not bad for a modern power supply, but not a stellar result either especially considering that most high class units get close to 85% nowadays. While the unit stays cool at >50% load because of its sheer size and two cooling fans, it becomes warm and eventually hot near its top power output. Not dangerously hot, but as the fans speed up the unit becomes noisy. It is audible even at very low outputs, but becomes noisy at 800-900W load, which even the most powerful systems will find hard to achieve.
