Super Flower Leadex PSUs are more silent then their EVGA G2/ P2 rebrands.
SF has better fan profile and better FDB fan.
But every EVGA G2 / P2 PSU will be dead silent while watching movies.
I have Cooler Master V1200 Platinum, its a big overkill for my PC which pulls max 400W from the wall (370W from the PSU).
This unit has hybrid semi passive fan mode at which fan is OFF even when I'm heavy gaming.
Even when I turn off Hybrid profile PSU fan never goes above 700 rpm...
