The manufacturer Sansun isn't well known yet, because they are a new company. If they continue delivering such solid products, I'm sure that this will change in no time.
For a price for which you often get only a plain and unsleeved power supply, Sansun is giving you a modularity feature which is usually found only on much more expensive PSUs. All cables are sleeved as well which helps keep your case look clean.
Not only the looks are good, the voltage stability is so as well. The 3.3V and 5V lines are very stable, the 12V line takes a few small dips during our load test, but you have to remember the price. Noise levels are also well below average. When the system is mainly idle the temperature controlled fan will run very slowly, making this one of the quietest PSU tested so far.
