Corsair RMi Series RM1000i Power Supply Review

Introduction & Packaging

The latest range of Corsair PSUs are here at last! The new RMi series is something of an upgrade, offering higher quality components, higher performance and more features compared to the last generation; pretty much everything you would expect from the latest range of anything tech related. Corsair has a rock solid reputation in the system building market, delivering popular and competitive products from CPU coolers, chassis, power supplies and more, so we’re hoping to see them put up a good fight on our test bench today.

The RMi series has a lot in common with the current RM series PSU units, as it still offers all the high-end features you would expect; 80 Plus Gold Certification, fully modular cables, Zero RPM fan modes (up to 40% load), silent component selection (reduced coil whine) and LLC resonant mode topology w/ DC to DC (improves efficiency and voltage regulation). However, the RMi series is setting the bar even higher, with a 7 year warranty, all Japanese capacitors, full output at 50c, a fluid dynamic bearing fan, digital output for additional Corsair Link monitoring capabilities, as well as additional Corsair Link control capabilities, which includes custom fan profiles and the ability to toggle the +12v rail from multiple to 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 RM1000i offers up, you guessed it, 1000 watts of power. There’s a nice and clear image of the PSU on the front of the box, as well as a quick run-down of the major features on the rest of the packaging, such as the 80 Plus Gold certification and semi-passive cooling design.

In the box for the RM1000i, you’ll find the manual, warranty guide, power cable, screws and a few cable ties to help you keep everything neat and tidy.
