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.
Voltage regulation on this power supply is pretty darn stellar and was within +-1.65% on all rails.
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.
Efficiency meets and is slightly better than the 80 Plus Bronze certification this unit has.
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 wasn’t the strongest we’ve seen but was by no means bad, this is still an above average power supply.
C’mon Ryan, you never mentioned the multi coloured cables in your list of cons. You must be slipping. ;-)
Thanks…I think I had a few Ciders when I wrote this one!
Lol.
