The Tuniq brand name was created by Sunbeamtech a few years back in order to represent a new, more refined line of computer components. They started off with an excellent CPU cooler (the Tuniq Tower 120), added a few cases, and now have a growing line of power supplies. We checked out their 950W Miniplant power supply several months ago, and now we have their highest rated model, the 1200W Ensemble.
The promotional image above reveals that the Ensemble is an oversized unit with a no nonsense appearance which is hopefully mirrored by its performance. Before taking a closer look at the sample provided for review, let's take a look at some published data on the Ensemble 1200W power supply, as taken from the product page on the Tuniq website.

While many manufacturers have gone back to a single 12V rail design, the Ensemble makes use of four 12V rails. Each one is rather beefy, with two rated at 20A and two rated at 25A. Comparing this unit to the smaller (in physical size and power rating) Tuniq Miniplant, the key differences are that all of the 12V rails on the Miniplant were 20A, and the 3.3V rail was rated a bit lower at 24A.
