Corsair is one of the biggest names in the industry, covering a wide range of products from chassis, peripherals, cooling, audio and more importantly today, power supplies. Their latest range of PSUs promises to deliver some impressive performance figures and we?ve got two of their new RMi series products on our test bench and ready to rock. First up, we have the 650 watt unit, which to some may not sound like a lot of power, but from my experience, few systems pull more than 500 watts even at full load, so there's no doubt in my mind that this unit is the one aimed at mid to high-end gaming systems and day-to-day users.

The RMi series is a big improvement on the current RM series of PSUs. They still offer the high-end features of the previous generation, such as 80 Plus Gold Certification, modular cables and more. With the added bonus of a 7-year warranty, full Japanese capacitors, a fluid dynamic bearing fans, digital output (Corsair Link), custom fan profiles and something for the enthusiast crowd, the ability to switch the +12v rail between multiple and single rail modes.
