SuperFlower Leadex Platinum 750W & Titanium 1000W Review

Efficiency, PFC and Voltage Regulation – Leadex Titanium 1000W

Voltage Regulation

To test voltage regulation we load the power supply to five different load scenarios that give an equal spread of load across every single rail. So that means 20% on all rails, 40% on all rails and so on. We then calculate the average deviance of each rail from its expected voltage.

Due to the limitations of our load tester, we had to split the 12v rail across multiple “simulated” rails. Power output on this unit is stunning, very tight regulation for the most part, with just the 5VSB being 1.44% high, but still fairly consistent results regardless.

Power Efficiency

Power efficiency is measured by calculating actual supplied wattage divided by the wattage drawn at the wall/plug, multiplied by 100 to give a percentage. We then compare that to the particular 80 Plus certification the company claims to see if it meets that. You can see the 80 Plus certifications below, we always test 230v power supplies.

The 1000W Titanium rating performed spectacularly in this test, exceeding the rating in most load scenarios, with only the 80% load dropping 0.8% below spec.

Power Factor Correction

Power Factor Correction is the ratio of the real power flowing to the load, to the apparent power in the circuit. The aim of PFC is to make the load circuitry that is power factor corrected appear purely resistive (apparent power equal to real power). In this case, the voltage and current are in phase and the reactive power consumption is zero. The closer the number to one the better as this allows the most efficient delivery of electrical power (Source – Wikipedia).

PFC was incredible on this unit, some of the best scores I’ve ever seen!
