Introduction

I would like to thank Thermaltake for supplying me with the unit for review.

Packaging

Box contents:

• Power supply unit
• English Manual
• Power Cord
• Three Screw packages
• 120mm Fan
• 5.25" Drive Bay Watts Viewer
• Cables

Modularity is becoming more and more popular in power supplies. The placement of the individual connectors is intelligent. The hardest one to reach, when the PSU is installed in the case, is the ATX power connector, which you will probably never remove. The easiest to plug in and out are the drive connectors.



When switched on, the inside fan is lighting up blue.



The motherboard power connector is compatible with both ATX 20 pin and 24 pin. If you have an ATX 20 connector on your board, just do not plug in the additional plug.



Two cables to power PCI-Express video cards are included with the PSU. Since both ends of the cable have the same plug, each plug is labelled, where it goes.



The black paint is matte and does not take any fingerprints.



Thermaltake's 120mm add-on fan is way too noisy to be used in a normal PC environment - but it moves a lot of air.

Watts Viewer

A really nice feature is the included watts viewer. It measures total system power consumption on the DC side of the power supply. If you don't like it - you won't have to use it, the PSU will work fine without the Watts Viewer connected.



The two knobs on the left and right are used to control the fan speeds of the PSU and the additional 120mm fan. What I noticed, is that you can only increase the fan speed of the PSU fan, not decrease it (compared to controller not connected).



This is the heart of the Watts Viewer. A small PCB with a microcontroller on it. The microcontroller is responsible for converting the measured watts into a suitable output for the LED readout.



The accuracy of the Watts Viewer is good, certainly not lab grade, but good enough to get a realistic feeling of the system's power consumption.
This maximum readout of 480W was achieved by adding a 120W and 100W high power resistor to the PSU output lines. When the DC side was pulling 480W, we measured 630W load on the AC side, not really efficient (76% efficiency).
