We think it is simply ridiculous that in this day and age there are still well-known brands labeling power supplies with fake wattages.
Even if this unit were labeled with its real wattage (430 W), it would still be a bad choice. Voltages drop below the minimum allowed, and noise and ripple levels can increase above the maximum allowed, causing your computer to behave erratically. Also, this unit presents low efficiency.
There are better power supplies at the same wattage costing less.
In summary, we must recommend that you stay away from this power supply.
