Conclusion:

After using the Cooltek 600 Watt for several weeks under a very stressful environment I must say that I’m very pleased with its performance, all the rails proved to be extremely stable, showing virtually no fluctuation worth mentioning at all.

The Papst 120mm fan was never audible over the rest of the test system used in this review, which also was very pleasing. It is important for most people to keep system noise to a minimum and this unit would be a good choice for those with more sensitive ears.

The only drawback I can think of is really not a fault of the product itself; and that is the availability. I could not find a place in the UK nor the US that certainly stocks this product. Luckily I’m in Sweden where the Cooltek is widely available. Hopefully availability will improve since this is a really kick-ass product, and it should be on everyone’s shortlist.
