Thermaltake Toughpower GF3 1350W ATX v3.0 Power Supply Review

The Thermaltake GF3 1350W achieves high performance, and it could be even better, with a tighter load regulation at 12V and 5V and better transient response on the minor rails. 

Despite the high performance, some users will be troubled by the increased noise output, especially at moderate and high loads. This is not the ideal PSU for a silent system. The compact footprint for a 1350W PSU doesn't allow for a larger PCB which would help airflow. There could be a notable difference in noise output with a 180mm chassis instead of 160mm. 

The competing offerings that feature a 12VHPWR connector are limited to the SilverStone HELA 1300R Platinum, which is close enough to the overall performance with the GF3 1350, and the MSI MEG AI1300P PCIe5. 

So far, most brands haven't released high-capacity ATX v3.0 and PCIe 5.0-ready PSUs, but this will soon change. Using native connectors instead of adapters is always preferred in high-power applications.
