> It's not just about the wattage, it's about the stability- how stable is the supplied voltage and amperage; a criteria at which any iBall PSU completely fails.

> 400 W PSU will be enough but that iBall crap is not going to do it. You should get an Antec VP450P available at ~2700.

> The W is the symbol for Watt, the unit of power.
