Stress Test: Power Supplies Under Full Load

Profits Or Quality?

And how do things work out in actual practice? Power supply buyers and shoppers are generally naïve, trusting manufacturer claims blindly. As our test however reveals, these maximum output specifications are problematic - even in the upper price ranges. The "500 watts" stated, referring to the combined performance of the individual cables, fails by a long shot to reflect actual performance. And for users it is nearly impossible to check these performance specifications. This is why numerous manufacturers do not hesitate to use exaggerated wattage specifications in promoting their products to trump similar claims by competitors.
