We think it is simply ridiculous that in this day and age there are still well-known brands labeling power supplies with fake wattages. In the case of the Cooler Master Extreme 2 475 W, we can clearly see that this was done deliberately, as the product box and label list '475' without the letter 'W' or the word 'Watts' after it, probably to protect themselves in the case of an eventual lawsuit, by claiming that '475' is the 'model' of the power supply, not its wattage. However, the manufacturer's website clearly lists this unit as being a 475 W model. We are no consumer law experts, but we believe that knowingly overstating a product feature in order to improve sales is fraud, which is a crime in the United States as well as in most other countries.
Even if this unit were labeled with its real wattage (430 W), it would still be a terrible option. 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. To add insult to injury, there are better power supplies costing less, such as the Corsair CX430 V2.
In summary, we must recommend that you stay away from this power supply.
