Efficiency and Power Loss
Just last week we reviewed the PC Power & Cooling Silencer 750 QUAD which had a terrific efficiency of up to 86%. This week we see similar results. Even at lower inputs the efficiency reaches 83%, topped by a maximum 85% at 230VAC input. High efficiency is not the only important factor; efficiency at higher loads and over a range of loads is equally (if not more) important. A power supply that reaches 80% efficiency at a 10% load but then drops off at moderate to high loads wouldn't be desirable. Most PSUs are usually loaded at anywhere from 30 to 80% of their rated output, and maintaining a high efficiency at all loads would be the best possible result.
The Odin GT delivers another impressive result, with efficiency that is simply always good. Just after 20% load it is already over 80% efficient and it stays in the 80-85% efficiency range up until 100% load. If your PC has the need for this kind of power supply, you will get better than 80% efficiency and any load above approximately 150W. Considering the 800W rating, we expect this unit to go into systems that idle at 200W or more, so the end result is very good.
Due to the very high efficiency, the power loss is also very low and we see good results.

Read the test methodology article.neogodless - Tuesday, July 24, 2007 - link
Did you find any issues with the modular design? Obviously the efficiency was good. Could anything else have been affected by the additional connection point?Christoph Katzer - Tuesday, July 24, 2007 - link
I am in the midle of testing that with other models. I will write something which will bring light in this in matter...
