Introduction & Packaging


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.

“Corsair RMi Series power supplies are fully modular and optimized for silence and power efficiency. Zero RPM Fan Mode means that the fan doesn’t spin until the power supply is under heavy load, and the fan itself is custom-designed for low noise operation even at high loads. 80 PLUS Gold rated efficiency saves you money on your power bill, and the flat black cables are fully modular so you can enjoy fast, neat builds. The Corsair RMi Series is built with high-quality components, including all Japanese electrolytic capacitors, and is guaranteed to deliver clean, stable, continuous power, even at ambient temperatures as high as 50°C. Users can also install Corsairs Link software to monitor power usage and fan speed. With 650W, 750W, 850W and 1000W models available there is a Corsair RMi power supply suitable for potentially any PC configuration.” – Corsair

Packaging and Contents

The packaging is nicely designed, with a clear image of the PSU on the front of the box, as well as detailing the 7-year warranty and 80 Plus Gold certification.



In the box, you’ll find a power cable, some cable ties and mounting screws, the warranty guide and user manual. There was also a USB drive included, but at this time we think this may only be for press, not for consumers, as it contained information about the testing in-house of the power supply.
