"A reliable, potent power supply is required to prevent instability and system crashes. THG took a close look at 13 power supplies rated higher than 400 Watts. The test showed that lines supplying the system with +3.3, +5 and +12 Volt lines generated, on average, 20 Watts less overall power than was promised by the product name or product branding." -
