750W Platinum SFX PSU Yes, you read that correctly. Somehow, Corsair managed to cram 750 watts into an SFX PSU. Not only that, but the unit is also platinum rated. I got the chance to stumble across numerous SFX units, but the highest I had seen up to that point was 700W with a gold rating. The fact that Corsair pulled off that wattage and efficiency blew my mind. It even manages to have a silent fan mode below 50c.
