FTR2650V12

Fractal Design’s Tesla R2 650W power supply displayed good voltage regulation performance during our tests, with the voltage fluctuation being at 2.1%, lower than half of the 5% design limit. Ripple suppression and filtering however left us with mixed feelings. The filtering of the 12V line was very good, with the maximum voltage ripple at full load being 58mV, half of the 120mV design limit; however, the maximum ripple on the 3.3V and 5V voltage lines goes up to 40mV and 46mV respectively, which is very close to the 50mV maximum recommended value.
