Kolink Continuum 1200W Platinum Power Supply Review

Efficiency, PFC and Voltage Regulation
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.
The use of high-quality Nippon caps is paying off big time here, with pretty solid results and stable voltages. The 12V rail is running a little hot, but it’s still within a comfortable safe zone and there was no droop that could cause a brown out on your 12v hardware.
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.
80 Plus Platinum efficiency is a high mark to achieve and the latest from Kolink is right on the money here, sitting nicely on the requirements for 80 Plus certification.
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).
The PFC is very good here, we usually see a bigger drop around 40%, but this unit holds up very well with mostly consistant results right up to 100% load.
