With active PFC, there is also no need to set the voltage

Here you can also see the FFXIV Gil big gap between the maximum continuous wattage and the peak wattage.

PFC: it is always a good thing to have active PFC, PFC or Power Factor Correction helps improve the efficiency of a PSU, so that your PSU uses less electricity. With active PFC, there is also no need to set the voltage, it will automatically correct itself

Passive PFC is not very efficient, and it cannot use the full potential of the ac line. Passive PFc requires you to set the voltages as well.

While PSu's with Active PFC are more expensive to build, they are diffidently a must for high performance systems that eat lots of energy, because you diffidently want to save on your electricity bill.

Oh and in europe, you're required to have some sort of PFC in your PSU.

Modular Cabling: Modular cabling is always something that PC enthusiasts want. With modular cabling, most cables other then the 20+4 pin, 4 pin cpu, etc. come separate from the PSU.

With modular cabling, you only need to use the cables which you want. The rest of the cables can stay outside of the case, which will help improve your airflow.
