Corsair RMi Series RM650i Fully-Modular Review

A Closer Look – Exterior

Power Supply Unit

First impressions of the RM650i are very good, the design is certainly appealing, at least as appealing as you could expect from a PSU.

The top section has a nice fan guard and the housing of the PSU has a similar pattern that matches up, giving it a nice uniform look.

The black finish on the PSU is nothing special, but it’s got a light texture to it that looks presentable enough. The sticker on the side is nice and simple too, so it should blend in with most system builds easily enough.

Here you can see the RM650i supports a good load level on each rail, with up to 54A on the +12v rail as well as an overall total of 650W, although we’ll find out the true numbers shortly in our testing.

There’s all kinds of fun stuff going on here! First and most importantly is the Corsair link, which can be accessed via a 12C connector or the mini-USB port. There’s a LED indicator and one feature I really like, a fan test button. The fan test is great since this PSU can run passively, you may feel the need to check the fan still actually works, this should help alleviate your concerns. The PSU features a full modular design. There are four six-pin connectors for peripherals and SATA/Molex connectors, three eight-pin connectors, which can be used for the 4+4 CPU connector, as well as 6+2 PCI-E power cables. One of the things you may have noticed is that the 24-pin actually has 28-pins. There are extra “sense wires” on many of the connectors which the PSU uses these to help monitor and regulate the voltage.

There’s a good amount of ventilation around the back.

Cabling

All of the included cables are of a high quality and good length. What does please me is that the included cables are all black, with black braiding and black connectors and this will help give your system build a more uniform look overall. The SATA and MOLEX connectors are all flat cables which are much easier to work with in terms of cable managements.
