Surprisingly, the electrical performance of the Integra R2 750W power supply was better than that of the Tesla R2. Voltage regulation results were about the same, with all of the voltage lines displaying a variation of about 2.4% between minimum and maximum load. The filtering however is significantly better, with the 12V line displaying a maximum ripple of 54mV at maximum load and the 3.3V/5V lines develop a maximum voltage ripple of about 26mV each. These are very good performance figures, less than half the maximum recommended values.
