Corsair RMi Series RM1000i Power Supply Review

A Closer Look – Exterior

Power Supply Unit

First impressions of the RM1000i are very good, a really nice design overall and a set of tough fan guard rails on the top, with a pattern on the top panel that matches up with the fan guard rails.

There’s a 135mm fluid dynamic bearing fan in the top, which should provide great cooling performance.

The PSU comes with a fairly understated design, the monochrome design of the label means it should fit into virtually any build easily enough.

On the base, you can see the +12v rail will support up to 83.3A and, of course, that the PSU will handle up to 1000W maximum combined wattage.

One of the coolest features of the RM1000i is the Corsair Link, which can be connected via the proprietary cable or MiniUSB. This will allow you to monitor and adjust fan, voltage and rail configurations from your desktop. There’s also a fan test button, handy for seeing if it actually works if your PSU has been sat in passive mode for a long time. Obviously, there’s a wide range of connections on offer, with 6 x 6-pin, and 6 x 8-pin connectors, as well as the split 24-pin motherboard connector; this is more than enough for most high-end builds and multi-GPU configurations. On the PSU connectors, you’ll notice that the 24-pin is actually a 28-pin connector. These extra wires are “sense wires” which allow the PSU to better monitor and regulate voltage.

A good amount of ventilation around the back, as well as an easily accessible and large power switch.

Cabling

A great selection of cables overall, with multiple PCI-E connectors and plenty of SATA/Molex for those who have a lot of storage. Also, a very welcome addition is the all black cables, connectors and braiding, which should help you achieve a great looking build. The MOLEX and SATA cables are flat as well which make cable management much easier.
