They already are well known for motherboards, but Gigabyte also manufactures video cards, CPU coolers, and cases. The company's latest foray is power supplies. Anandtech takes a look at the Odin 800W unit. The Odin series from Gigabyte is actually built by Channel Well (CWT) which is headquartered in Taoyuan, a suburb of Taipei, Taiwan. They are in the same building as Enermax at the moment, but they are in the process of moving to a bigger facility. CWT has done some OEM production for other big brands in the past as well as power supplies under own brand for system-builders. Last year they started a price-war to get more retail OEM customers and succeeded quite well with it. One interesting feature Gigabyte has implemented is software to directly monitor the power supply. Although there were some problems with it, it certainly seems rather interesting.
Hopefully they work on the voltage regulation, as $230 can get you other units with tighter regulation there. I definitely dig the P-Tuner software idea, especially if they can work out the bugs. It'd be software monitoring that would be accurate.
