AMDBoard has posted a review on the Sansun Arctic 550W PSU

With the arrival of Athlon 64 X2 dual core and power-hungry graphic
chips like ATI Radeon X1000 or NVIDIA GeForce 7800, power supply makers have seen the need for more powerful PSUs loaded with more and more features like sleeved cables, modular design, ATX 2.0 compliance, 120mm LED fan, active PFC, 6-pin PCI-express connection, dual 12V rails and much more. The Sansun Artic 550W PSU is one of these and it also offers an impressive level of performance for a price that should not exceed 95$.
