Hi,
The Antec TrueControl II 550 is a nice power supply, and being able to adjust the voltages and power supply fan speed is nice.
For those who want SLI, the PSU does bring us another problem. The Antec TrueControl II 550 may not have enough juice. This is ok for the mid-range gaming crowd, but for the hardcore guys who have an SLI machine similar to my test bed's power, I suggest looking for a bigger supply.
