Going after the mainstream. Cooler Master has been known for its fair share of innovation over the years. The huge Cosmos chassis - new and old - remains a formidable case for building a high-spec rig into, but the company is aware that it needs a strong presence in more than one PC segment for continued growth. What better place to invest than in the power-supply market.

The firm has a dizzying array of PSUs because it services the retail and bulk-volume OEM markets concurrently. Breaking down the supplies via their 80 PLUS rating - a rough and ready reckoner of performance - shows there is scope to further extend its new MasterWatt brand by replacing the G- and V-series supplies, and this is exactly what it is doing with today's release of four 80 PLUS Bronze models.
