Thermaltake TR2 RX 750Watt Power Supply Review

The TT TR2 RX 750W is a single rail unit that is able to hold 672Watts on the 12volt rail alone. With this PSU you do not have to figure out what rail feeds what PCI-Express connectors or make sure you're not overloading the unit. This is a great feature that seems to be coming back among the 750Watt designs.

The specification label is much like the nutrition information on the side of a cereal box and will tell you most everything you need to know.  Here we can see the various power ratings and warnings including how the power is distributed.  You will also find the proudly displayed 5 year warranty and 80 Plus certification.  Along with the 80% efficiency rating the TR2 TX 750W comes with an Active PFC designed to regulate power usage and help save energy when power demand is low.

Some of the other safety features include:
- Over Voltage Protection
- Over Current Protection
- Over Load Protection
- Over Temperature Protection
- Under Voltage Protection
- Short Circuit Protection

Our testing is methodology not comprehensive; we don't have the required equipment to test power ripples and fluctuation so that will not be included.  However, this will not stop us from showing you the unit and testing how well it can power a beefy overclocked computer system, while keeping noise low and heat output to a minimum.  The 80 Plus certification and 5 year warranty should be enough confidence for most users, regardless of whatever abuse we intend to dish out.

Below is our testing setup, to ensure a good loading pattern we decided to play several hours of Crysis Warhead and monitor the noise and heat output for anything out of the ordinary.
