GideonTech.com posted a review on the Glacial Power 550W PSU

Glacialpower was kind enough to send over their 550W power supply, the GP-PS550BP. With an intelligent and silent design, it should provide great performance with some peace and quiet. I'll crack open the PSU to take a look inside as well to see what it's made of. With 550 Watts of power, it can power just about any mid-range PC you can piece together and possibly more.
